Introduction

Welcome to LumenLingo. These Terms of Service (“Terms”) govern your use of the LumenLingo mobile application (“the App”) operated by Lumenshore Limited (Company No. 09607326), a company registered in England and Wales (“Lumenshore”, “we”, “us”, or “our”).

By downloading, installing, or using LumenLingo, you agree to be bound by these Terms. If you don't agree with any part of these Terms, please don't use the App.

Acceptance of Terms

By accessing or using LumenLingo, you confirm that:

• You are at least 13 years old (or the minimum age required in your jurisdiction).
• If you are under 18, you have obtained consent from a parent or legal guardian.
• You have the legal capacity to enter into a binding agreement.
• You will comply with these Terms and all applicable laws.

Your Account

LumenLingo uses registered accounts. Authentication is provided through Clerk, including Google Sign-In when you choose it, and Rails maintains the corresponding LumenLingo account record. You are responsible for:

• Maintaining the security of your Google or other Clerk authentication credentials, active sessions, and device access.
• All activity that occurs through your use of the App.
• Keeping your device's operating system updated for the best experience and security.

Subscriptions & Billing

LumenLingo offers the permanent Free plan and the optional Royal monthly subscription. New customers also receive a separate 14-day period of complimentary Royal-level access.

• Billing — all subscriptions are processed and managed by Apple through the App Store. We do not handle payments directly.
• Free tier — provides access to core learning features with limited language pairs and practice modes.
• Complimentary access — every new customer receives 14 days of full Royal-level access after account creation. This is not a subscription, requires no payment method or purchase confirmation, creates no charge, and does not auto-convert or auto-renew.
• Royal subscription and renewal — Royal begins only after you tap Subscribe in the App and confirm the purchase with Apple. Once purchased, it renews monthly unless cancelled at least 24 hours before the end of the current billing period.
• Cancellation — you can cancel your subscription at any time through your Apple ID Settings → Subscriptions. Cancellation takes effect at the end of your current billing period.
• Refunds — refund requests are handled by Apple in accordance with their refund policies. Contact Apple Support for refund enquiries.
• Price changes — we may adjust subscription prices. You will be notified in advance, and changes apply only to your next renewal period.

VAT & Tax Treatment

Lumenshore Limited is registered for UK Value Added Tax (VAT No. GB 270411929). This section explains how VAT applies to our services.

In-App Purchases (iOS)

All in-app purchases made through Apple’s App Store are processed by Apple as the merchant of record. Under the UK Finance Act 2021, Apple is deemed the supplier for VAT purposes and collects and remits VAT to HMRC on all iOS in-app purchases made by UK consumers.

Prices displayed in the App Store include any applicable VAT. The final price charged is determined by Apple based on your App Store region and local tax rules.

Website Pricing

All prices displayed on our website for UK and EU consumers include VAT at the applicable rate. For UK consumers, the standard VAT rate of 20% applies to digital services.

Prices charged via Apple’s App Store may vary by location. The price shown on our website is indicative; the final price is always as displayed in the App Store at the time of purchase.

Tax Records

We retain all VAT and financial records for a minimum of 6 years in accordance with HMRC requirements. Our VAT returns are filed digitally via Making Tax Digital (MTD) compatible software as required by UK law.

EU VAT on Digital Services

As a UK-based provider of digital services to EU consumers, we comply with EU VAT rules for cross-border digital supplies.

Apple as EU Marketplace Operator

Under EU marketplace rules and DAC7, Apple is deemed the supplier for VAT purposes for all in-app purchases made through the App Store by EU consumers. Apple collects and remits VAT at each EU member state’s rate (e.g. Germany 19%, France 20%, Spain 21%, Poland 23%, Italy 22%).

Lumenshore’s obligation is limited to proper revenue recognition of the net amount received from Apple after deduction of commission and VAT.

One Stop Shop (OSS)

For any digital services sold directly to EU consumers outside the App Store, we use the UK Non-Union One Stop Shop (OSS) scheme administered by HMRC. This allows us to account for EU VAT through a single quarterly return rather than registering in each member state individually.

EU VAT is applied at each member state’s rate and remitted through HMRC to the relevant tax authorities. Records of all EU supplies are retained for a minimum of 10 years.

B2B Digital Services

Where digital services are supplied to EU businesses, the reverse charge mechanism applies. The EU business customer self-accounts for VAT in their own country. We verify EU VAT registration numbers via the VIES system before zero-rating any invoice.

Customer Location Evidence

We comply with the EU two-piece-of-evidence rule, which requires at least two non-contradictory pieces of evidence of customer location (such as IP address and billing address). For App Store purchases, Apple provides this evidence automatically.

International Tax Obligations

As a global service provider, Lumenshore monitors tax obligations across all jurisdictions where our app is available. In most markets, Apple handles tax collection as the marketplace operator.

Japan (Consumption Tax)

Japan’s Consumption Tax (JCT) of 10% applies to digital services. Apple, as a registered foreign business in Japan, handles JCT collection and remittance for all iOS in-app purchases. Direct sales to Japanese consumers exceeding ¥10 million annually would require separate JCT registration.

United States (Sales Tax)

There is no federal digital services tax in the US. State-level sales tax varies and not all states tax digital services. Apple handles sales tax collection for in-app purchases across all US states in accordance with each state’s economic nexus rules.

Australia (GST)

Australia’s Goods and Services Tax (GST) of 10% applies to digital products supplied to Australian consumers. Apple handles GST collection for App Store purchases. Direct sales exceeding AUD 75,000 annually would require separate GST registration.

India (GST)

India’s GST of 18% applies to online information and database access services. Apple handles GST for in-app purchases. Non-resident providers may need separate GST registration for direct sales to Indian consumers.

OECD Global Minimum Tax

The OECD Pillar Two global minimum tax of 15% currently applies to multinational enterprises with consolidated revenue exceeding €750 million. This threshold does not currently apply to Lumenshore, but we monitor developments for potential future changes.

UK Corporation Tax

Lumenshore pays UK Corporation Tax on worldwide profits at the applicable rate (currently 25% for profits over £250,000, or the small profits rate of 19%). We assess eligibility for R&D Tax Credits for qualifying software development expenditure and Creative Industry Tax Relief where applicable.

Transfer Pricing

As a single-entity company, Lumenshore does not currently have intercompany transactions requiring transfer pricing documentation. Should the corporate structure change, we will comply with OECD Transfer Pricing Guidelines and UK legislation.

Pricing Display Compliance

Lumenshore is committed to transparent, accurate pricing across all platforms. This section details our compliance with pricing display regulations in every jurisdiction where our app is available.

UK Price Marking Order 2004

All prices displayed to UK consumers on our website include VAT at the applicable rate. Prices shown represent the total amount payable with no hidden charges. Where a range of pricing tiers is offered, pricing starts from the lowest available tier (Free, £0.00).

EU Consumer Rights Directive

Prices are displayed in a clear and comprehensible manner. The total price including all applicable taxes is shown before any purchase commitment. Subscription billing frequency (monthly) is clearly indicated alongside the price. No additional delivery or postal charges apply to our digital service.

EU Omnibus Directive

In compliance with the Price Indication Directive 98/6/EC as amended by the Omnibus Directive, any promotional or reduced pricing on our website will display the previous lowest price charged during the 30 days prior to the reduction. Our current pricing tiers are standard ongoing prices and are not presented as time-limited discounts.

iOS App Pricing

In-app purchases use Apple StoreKit to display localised prices that include local taxes automatically. The price shown in the app always matches the price Apple will charge. Regional pricing follows Apple’s App Store Connect tier configuration, ensuring consistency between displayed and charged amounts.

Website Pricing

Our website displays prices in GBP (British Pounds Sterling) inclusive of UK VAT. When purchasing via the iOS app, the final price is determined by Apple’s App Store based on your location and local tax rules. We do not display misleading discount claims or artificial price reductions.

Distance Selling & Consumer Rights

Your subscription to LumenLingo is a distance contract. The following information is provided in compliance with the UK Consumer Contracts Regulations 2013 and the EU Consumer Rights Directive (2011/83/EU):

• Trader identity — Lumenshore Limited (company number 09607326), registered in England & Wales. VAT registration: GB 270411929.
• Service description — LumenLingo is a digital language-learning application offering flashcards, grammar exercises, word-building games, soundscapes, and visual themes across multiple language pairs.
• Price & payment — subscription prices are displayed in the App and on our website, inclusive of applicable taxes. All payments are processed by Apple through the App Store. Lumenshore does not handle payment card details.
• Contract duration — subscriptions are monthly rolling contracts with no minimum commitment. They auto-renew unless cancelled at least 24 hours before the end of the current billing period.
• Cooling-off period — under the Consumer Contracts Regulations 2013, you have a 14-day right to cancel distance contracts without giving any reason. When you initiate a purchase through the App Store, Apple presents the subscription terms including the start date and auto-renewal terms. By confirming the purchase (via Face ID, Touch ID, or passcode), you expressly consent to the immediate supply of digital content and acknowledge that you lose your 14-day cancellation right once the digital content is made available to you.
• Consent confirmation — we will send a confirmation of your consent to immediate performance via the App Store receipt delivered to your Apple ID email address, which constitutes a durable medium under CCR 2013 reg. 16.
• Cancellation — you may cancel future renewals at any time via Settings → Apple ID → Subscriptions. Cancellation takes effect at the end of the current billing period. You retain access to premium features until that date.
• Refunds — all refund requests are handled by Apple. To request a refund, visit reportaproblem.apple.com. Lumenshore does not process refunds directly, as Apple is the merchant of record for all App Store purchases.
• Complaints — if you have a complaint about our service, please contact us at Checking secure contact. We aim to resolve all complaints within 14 days.

Acceptable Use

You agree to use LumenLingo only for lawful purposes and in accordance with these Terms. You must not:

• Reverse engineer, decompile, or disassemble any part of the App.
• Attempt to access, tamper with, or use non-public areas of the App or its systems.
• Copy, modify, distribute, or create derivative works based on the App.
• Use the App in any way that could damage, disable, overburden, or impair its functionality.
• Use automated scripts, bots, or other tools to interact with the App.

Intellectual Property

All content within LumenLingo — including but not limited to flashcard content, translations, audio, soundscapes, visual designs, shader effects, animations, the LumenLingo name, and the Lumenshore brand — is the intellectual property of Lumenshore Limited and is protected by copyright, trademark, and other intellectual property laws.

Your subscription grants you a limited, non-exclusive, non-transferable, revocable licence to use the App for personal, non-commercial language-learning purposes. This licence does not include the right to:

• Reproduce, distribute, or publicly display any App content.
• Use any content for commercial purposes or in competing products.
• Remove or alter any proprietary notices or labels.
• Use any automated means (including bots, scrapers, crawlers, spiders, or data-mining tools) to access, copy, monitor, or extract any content from the Service.
• Create derivative works based on LumenLingo content, or reverse-engineer any aspect of the App.

Copyright Infringement & DMCA

Lumenshore Limited respects the intellectual property rights of others and expects users to do the same. If you believe that any content available through LumenLingo infringes your copyright, you may submit a notice of claimed infringement.

Your notice must include:

• A physical or electronic signature of the copyright owner or a person authorised to act on their behalf.
• Identification of the copyrighted work claimed to have been infringed.
• Identification of the material that is claimed to be infringing, with information reasonably sufficient to permit us to locate it.
• Your contact information, including address, telephone number, and email.
• A statement that you have a good-faith belief that the use of the material is not authorised by the copyright owner, its agent, or the law.
• A statement, under penalty of perjury, that the information in the notice is accurate and that you are authorised to act on behalf of the copyright owner.

Send copyright infringement notices to: legal@lumenlingo.com

Lumenshore will respond to valid takedown notices in accordance with the US Digital Millennium Copyright Act (17 U.S.C. § 512) and equivalent UK and EU legislation. Repeat infringers may have their accounts terminated.

Repeat Infringer Policy: Lumenshore maintains a policy to terminate, in appropriate circumstances, the accounts of users who are repeat infringers of copyright. Three or more valid infringement notices against an account within any twelve-month period will result in permanent account termination.

Counter-notification: If you believe content was removed in error, you may submit a counter-notification to legal@lumenlingo.com including: (i) identification of the removed material, (ii) a statement under penalty of perjury that the removal was a mistake, (iii) your name, address, and consent to jurisdiction, and (iv) your physical or electronic signature. Counter-notifications are processed in accordance with 17 U.S.C. § 512(g).

Content Protection & Anti-Scraping

You may not use any automated means — including bots, scrapers, crawlers, spiders, data-mining tools, or artificial intelligence training pipelines — to access, copy, monitor, or extract any content from the Service. Specifically:

• Systematic or bulk downloading, copying, or redistribution of flashcard content, vocabulary lists, grammar explanations, example sentences, or audio files is strictly prohibited
• Any automated access that exceeds reasonable human browsing patterns constitutes unauthorised use and grounds for immediate account termination
• You may not compile, aggregate, or create derivative datasets from LumenLingo content for any purpose, including machine-learning model training

Lumenshore employs technical protection measures to safeguard its content. You further agree that:

• Lumenshore employs rate limiting, access controls, and content-integrity measures; circumventing, bypassing, or disabling any of these constitutes unauthorised access
• Circumventing technical protection measures may violate the UK Computer Misuse Act 1990, the US Computer Fraud and Abuse Act (18 U.S.C. § 1030), and EU Directive 2009/24/EC on the legal protection of computer programs
• Automated bulk access may result in IP blocking, API key revocation, and account termination without prior notice

Data Export & Competitive Use Restriction

Data exported under GDPR Article 20 (data portability), the UK GDPR, or equivalent data-protection laws is provided for your personal use only. The following restrictions apply:

• You may not use exported data, or any data derived from or informed by your use of the Service, to create, assist in creating, train, or improve a competing product or service
• You may not licence, sell, distribute, or otherwise make exported LumenLingo content available to third parties for commercial purposes
• This restriction does not limit your statutory data portability rights — it restricts only the commercial exploitation of Lumenshore’s proprietary learning content accessed via your account

This clause does not apply to data you independently created or obtained outside the Service, nor does it restrict any rights that cannot lawfully be excluded.

User Content & Data

Your learning data (progress, preferences and practice history) is stored on your device by default. If you enable Cloud Sync, selected data is encrypted on your device and replicated as ciphertext to Lumenshore’s cloud-backup service and your private CloudKit container. Lumenshore does not claim ownership of your personal learning data.

If we introduce features that allow you to submit, post, or share content (such as notes, comments, or shared word lists), you retain ownership of that content but grant Lumenshore Limited a non-exclusive, worldwide, royalty-free licence to use, display, and distribute it within the Service. You may request removal of your content at any time.

For more details on how we handle data, please review our Privacy Policy.

Disclaimers

LumenLingo is provided on an “as is” and “as available” basis. While we strive for accuracy and quality, we make no warranties, expressed or implied, regarding:

• The accuracy or completeness of any language content or translations.
• Uninterrupted or error-free operation of the App.
• The results you may achieve from using the App.
• The availability of specific features at any given time.

LumenLingo is a supplementary learning tool. It is not a substitute for professional language instruction, certified translation services, or academic coursework.

Educational Content Disclaimer

LumenLingo is a language learning aid and supplementary tool. It is not a certified educational institution and does not award recognised qualifications.

We do not guarantee fluency or any specific level of proficiency. Content is provided for general learning purposes and should not be relied upon for professional translation, interpretation, or academic assessment.

You acknowledge that your expectations should be commensurate with a consumer digital content subscription. Lumenshore does not represent that the Service will meet your specific learning objectives, timeline, or professional needs.

Limitation of Liability

To the fullest extent permitted by applicable law, Lumenshore Limited shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill arising from:

• Your use of (or inability to use) the App.
• Any errors, omissions, or inaccuracies in the content.
• Unauthorised access to your device or data (not caused by our negligence).
• Any interruption or cessation of the service.

Lumenshore’s total aggregate liability for all claims arising from these Terms or your use of LumenLingo shall not exceed: (a) for Free tier users — ten pounds sterling (£10); (b) for paid subscribers — the total subscription fees actually paid by you in the twelve (12) months immediately preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits our liability for: death or personal injury caused by our negligence; fraud or fraudulent misrepresentation; or any other liability that cannot be excluded or limited by applicable law, including your statutory rights under the Consumer Rights Act 2015 (UK) or the EU Consumer Rights Directive.

This limitation of liability is consistent with the Limitation of Liability clause in our End-User Licence Agreement (EULA). Where both agreements apply, the more favourable limitation (from the user’s perspective) shall prevail.

Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations under these Terms where such failure or delay results from causes beyond its reasonable control, including but not limited to: natural disasters, government actions, internet or telecommunications failures, pandemic, civil unrest, or third-party service provider outages (each a "Force Majeure Event").

The party affected by a Force Majeure Event shall promptly notify the other party in writing, describing the nature of the event and its expected duration.

The affected party shall use reasonable endeavours to mitigate the effect of the Force Majeure Event and to resume performance of its obligations as soon as reasonably practicable.

During a Force Majeure Event, the affected party’s obligations are suspended for the duration of the event.

If a Force Majeure Event continues for more than 90 consecutive days, either party may terminate the agreement by giving written notice to the other party. In the event of such termination, paid subscribers will receive a pro-rata refund for any pre-paid subscription period remaining after the date of termination.

Indemnification

You agree to indemnify, defend, and hold harmless Lumenshore Limited, its directors, officers, employees, and agents from any claims, damages, losses, and expenses (including reasonable legal fees) arising from:

• Your breach of these Terms;
• Your violation of any applicable law or the rights of any third party;
• Any content you submit to or through the Service.

This indemnity does not apply to the extent that the claim arises from our negligence, our breach of contract, or defective digital content supplied by us.

If you are a consumer in the United Kingdom or the European Union, this indemnity clause does not affect your statutory rights under the Consumer Rights Act 2015 or equivalent consumer protection legislation. Nothing in this clause requires you to indemnify us for losses arising from our own fault.

Lumenshore reserves the right to assume the exclusive defence and control of any matter otherwise subject to indemnification by you, in which event you agree to cooperate with Lumenshore in asserting any available defences.

Lumenshore Limited will indemnify, defend, and hold harmless you from and against any third-party claims, damages, and reasonable legal costs arising directly from: (a) Lumenshore's negligence or wilful misconduct; (b) Lumenshore's breach of its obligations under these Terms; or (c) Lumenshore's infringement of your intellectual property rights. This reciprocal indemnity is subject to the same limitations of liability set out in these Terms.

Liability Caps

If you use the Service on a free tier, Lumenshore's total aggregate liability to you for all claims arising from or related to the Service shall not exceed ten pounds sterling (£10).

If you use the Service on a paid subscription, Lumenshore's total aggregate liability to you shall not exceed the total amount you have actually paid to Lumenshore in the twelve (12) months immediately preceding the event giving rise to the claim.

For purchases made through the Apple App Store, the liability cap is based on the total amount you paid, not the net amount received by Lumenshore after Apple's commission.

Exclusion of Consequential Damages

To the maximum extent permitted by applicable law, Lumenshore shall not be liable for any: loss of data, lost profits, lost revenue, lost savings, loss of goodwill, business interruption, cost of substitute services, incidental damages, consequential damages, special damages, exemplary damages, or punitive damages.

This exclusion applies even if Lumenshore has been advised of the possibility of such damages, and even if a limited remedy set forth herein fails of its essential purpose.

Nothing in this section excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any liability that cannot be excluded or limited under the Consumer Rights Act 2015 or other applicable law.

Warranty Disclaimer

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, completeness, reliability, availability, timeliness, or security.

We do not warrant that the Service will be uninterrupted, error-free, virus-free, or that defects will be corrected.

Nothing in these Terms affects your statutory rights under the Consumer Rights Act 2015 (UK) or equivalent consumer protection legislation in your jurisdiction.

No Liability for User Reliance

Lumenshore is not liable for any decisions made or actions taken by users in reliance on the content provided through the Service.

Users are solely responsible for verifying the accuracy of any translation or linguistic information before relying on it for any purpose.

Third-Party Services

Lumenshore is not liable for the acts or omissions of third-party services, including Apple, Vercel, Sentry, or any payment processor.

Apple is the merchant of record for all iOS in-app purchases. Billing disputes related to App Store purchases should be directed to Apple.

Service Availability

We do not guarantee any specific level of uptime or availability for the Service.

We may perform scheduled or unscheduled maintenance with or without prior notice. The Service may experience interruptions due to third-party providers, network issues, or events beyond our control.

No service level agreement (SLA) applies unless separately agreed in writing.

Consumer Fairness Notice

These Terms have been drafted in plain, intelligible language in accordance with the Consumer Rights Act 2015, section 68. If any term is found to be unclear, it will be interpreted in your favour as the consumer.

Nothing in these Terms excludes or limits our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot lawfully be excluded or limited under the Consumer Rights Act 2015, section 65, or other applicable law.

Your statutory rights as a consumer under the Consumer Rights Act 2015 are not affected by any provision of these Terms. In the event of conflict between these Terms and your statutory rights, your statutory rights shall prevail.

Your Consumer Rights

If you are a consumer in the United Kingdom, you have statutory rights under the Consumer Rights Act 2015 and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. Nothing in these Terms excludes or limits those rights.

Digital Content Standards

Under the Consumer Rights Act 2015, digital content supplied by LumenLingo must be:

• Of satisfactory quality — free from defects, safe, and durable, taking into account any description, the price, and all other relevant circumstances
• Fit for a particular purpose — suitable for any purpose you made known to us before or at the time of purchase
• As described — matching any description we provided to you, including features listed on our website and the App Store

Your Remedies

If our digital content does not meet these standards, you are entitled to the following remedies:

• Repair or replacement — we will fix the fault or provide a replacement at no cost to you, within a reasonable time and without significant inconvenience
• Price reduction — if repair or replacement is not possible, or not carried out within a reasonable time, you may be entitled to a price reduction (up to the full amount)
• Right to a refund — for content that was faulty at the time of supply, you may be entitled to a full or partial refund

14-Day Cooling-Off Period

Under the Consumer Contracts Regulations 2013, you have a 14-day cooling-off period from the date of purchase in which you may cancel an online subscription and receive a full refund, without giving any reason.

Because LumenLingo subscriptions are purchased through Apple’s App Store, the cooling-off period is managed by Apple in accordance with their refund policies. If you wish to exercise this right, please request a refund through Apple.

Refunds via Apple

All LumenLingo in-app purchases and subscriptions are processed by Apple as the payment provider. Refund requests are handled by Apple in accordance with their policies.

To request a refund, visit reportaproblem.apple.com or contact Apple Support. Lumenshore Limited fully supports this process and will cooperate with Apple on any refund enquiry.

Nothing in these Terms affects your statutory rights as a consumer. If there is any conflict between these Terms and your statutory rights, your statutory rights will prevail.

EU Consumer Rights Directive

If you are a consumer in the European Union, you have additional rights under the EU Consumer Rights Directive (2011/83/EU). These rights apply alongside our standard terms and offer you specific protections when purchasing digital services.

Pre-Contractual Information

Before you subscribe, we provide all information required under Article 6 of the EU Consumer Rights Directive, including:

• Trader identity — Lumenshore Limited, registered in England & Wales (company number 09607326), VAT: GB 270411929
• Service description — AI-powered language learning application with flashcards, practice exercises, and adaptive learning
• Total price — all prices are displayed inclusive of applicable VAT/taxes. Subscription prices are fetched dynamically from Apple and shown in your local currency
• Payment method — all payments are processed by Apple through the App Store. No hidden charges or additional fees apply
• Contract duration — monthly rolling subscription with no minimum commitment

Right of Withdrawal

Under the EU Consumer Rights Directive, you have a 14-day right of withdrawal from the date of purchase. However, by starting to use the digital content immediately, you expressly consent to the performance of the contract beginning before the withdrawal period expires and acknowledge that you lose your right of withdrawal once the digital content has been fully provided.

For subscriptions purchased through the App Store, withdrawal and refund requests are handled by Apple. You may request a refund at reportaproblem.apple.com within 14 days of purchase.

Prohibition of Hidden Charges

In compliance with Article 22 of the EU Consumer Rights Directive, LumenLingo does not impose any charges beyond those clearly disclosed before purchase. All subscription prices are shown upfront, inclusive of applicable taxes. There are no hidden fees, delivery charges, or additional costs.

Order Acknowledgement

In compliance with Article 8(2) of the EU Consumer Rights Directive, our subscription purchase buttons clearly indicate the obligation to pay by displaying the subscription price. By tapping the purchase button, you explicitly acknowledge that the order implies an obligation to pay.

Easy Cancellation

You can cancel your subscription at any time with the same ease as subscribing. To cancel, open your device Settings, tap your name, then Subscriptions, select LumenLingo, and tap Cancel Subscription. Cancellation takes effect at the end of the current billing period, and you retain access until then.

These EU consumer rights are in addition to, and do not replace, any other rights you may have under applicable national consumer protection laws.

Aggregated & De-identified Data

Our practices regarding the collection, use, and protection of aggregated and de-identified data are described in detail in our Privacy Policy. Please refer to the Aggregated & De-identified Data section of our Privacy Policy for full details.

Termination

You may stop using LumenLingo at any time by deleting the App. Your subscription, if active, should be cancelled separately through Apple's subscription management.

We reserve the right to suspend or terminate access to the App if we reasonably believe you have violated these Terms. In the event of termination:

• Your licence to use the App is immediately revoked.
• Local learning data remains on your device until you delete it. Account data and optional encrypted Cloud Sync copies are handled separately through the App’s account-deletion flow, Apple’s private CloudKit controls, and the retention exceptions in our Privacy Policy.
• Active subscriptions should be cancelled through Apple.
• Provisions that by their nature should survive termination will remain in effect.

Geographic Restrictions

Access to LumenLingo may be restricted in certain territories due to applicable sanctions laws and App Store distribution policies:

• LumenLingo is distributed exclusively through the Apple App Store. Apple restricts App Store access in comprehensively sanctioned countries, including Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions.
• Lumenshore Limited does not independently distribute the App to any jurisdiction subject to UK, US, or EU sanctions.
• If you access the Service from a jurisdiction where such access is prohibited by applicable law, you do so at your own risk and are solely responsible for compliance with local laws.

We reserve the right to limit or terminate access to the Service in any jurisdiction where we determine, in our sole discretion, that legal compliance requires such action.

Sanctions & Trade Compliance

Lumenshore Limited is a UK-incorporated company (Company No. 09607326) that distributes LumenLingo globally via the Apple App Store. We maintain compliance with applicable sanctions regimes across all jurisdictions in which we operate.

UK Sanctions Compliance

We comply with the Sanctions and Anti-Money Laundering Act 2018 and regulations administered by the Office of Financial Sanctions Implementation (OFSI). As a consumer language-learning application, LumenLingo is classified as non-strategic software and is generally exempt from most trade restrictions. We review OFSI consolidated sanctions lists and do not knowingly provide services to sanctioned individuals or entities.

US OFAC Sanctions

Because LumenLingo is distributed via the Apple App Store, which operates from the United States, US Office of Foreign Assets Control (OFAC) sanctions apply to distribution. Apple already restricts App Store access in comprehensively sanctioned countries including Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions. Lumenshore does not independently distribute to any sanctioned territory.

EU Sanctions Framework

We monitor EU sanctions lists for changes that may affect the provision of digital services, particularly in regions relevant to our Arabic-speaking and Ukrainian user base. Apple’s App Store distribution restrictions align with EU sanctions requirements. We do not provide services to EU-sanctioned individuals or entities.

Ukraine — Service Availability

Ukraine is not subject to UK, EU, or US sanctions. Services to Ukrainian users are lawful and actively supported. LumenLingo provides a Ukrainian locale and three Ukrainian language pairs (UA↔EN, UA↔PL, PL→UA). However, the Crimea, Donetsk, and Luhansk regions have restricted status under multiple sanctions regimes, and Apple restricts App Store access in these regions.

Sanctions Screening

For account-bearing users who make purchases, sanctions screening is handled at the payment infrastructure level by Apple’s App Store. Apple performs Know Your Customer (KYC) checks on Apple ID accounts and restricts access from sanctioned territories. LumenLingo does not process payments directly and relies on Apple’s compliance infrastructure for transaction-level screening.

Encryption & Export Controls

LumenLingo uses industry-standard encryption for local protection, authenticated network transport, and optional Cloud Sync. This section documents that use for transparency and regulatory compliance.

Encryption Audit

The following standard encryption technologies are used within LumenLingo:

• HTTPS/TLS — All network communications use Transport Layer Security for data in transit
• Device-encrypted Cloud Sync — selected learning data is encrypted on the device before ciphertext is backed up to Lumenshore’s Rails-backed service and the user’s private CloudKit container
• SwiftData File Protection — Local data at rest is protected by iOS file-level encryption
• Keychain Services — Sensitive credentials are stored in the iOS Keychain with hardware-backed encryption

US Export Administration Regulations (EAR)

LumenLingo uses standard published encryption through HTTPS/TLS, Apple platform cryptography and file protection, Keychain Services, and device-side encryption for Cloud Sync. These technologies are used for authentication, secure transport, local protection, and encrypted backups; the App does not provide user-configurable cryptographic functionality.

French Encryption Import Controls

LumenLingo uses standard HTTPS/TLS, Apple platform security, Keychain Services, and device-side encryption for Cloud Sync rather than user-configurable cryptographic functionality. Any applicable French encryption import or declaration treatment is assessed on that basis.

App Store Connect Export Compliance

LumenLingo’s export-compliance answers are provided through Apple’s App Store Connect. The App uses HTTPS/TLS, Apple platform security, Keychain Services, and device-side Cloud Sync encryption for selected backups.

Dispute Resolution

We believe most concerns can be resolved quickly and amicably. If a dispute arises between you and Lumenshore in connection with these Terms or your use of the Service, the following procedure applies:

Step 1 — Informal Resolution

Before initiating any formal proceedings, please contact us at legal@lumenlingo.com with a detailed description of your concern. We commit to engaging in good faith discussions to resolve the matter within 30 days of receiving your communication.

Step 2 — Mediation

If informal discussions do not resolve the dispute within the 30-day period, either party may propose mediation through a mutually agreed mediator. Mediation is voluntary and the costs shall be shared equally unless otherwise agreed.

Step 3 — Court Proceedings

If the dispute remains unresolved after good faith informal resolution and, where attempted, mediation, either party may commence court proceedings. The courts of England and Wales shall have exclusive jurisdiction, subject to the consumer protection carve-outs below.

EU Online Dispute Resolution

If you are a consumer in the European Union, you may also use the European Commission's Online Dispute Resolution (ODR) platform to resolve disputes: https://ec.europa.eu/consumers/odr/. Our email for ODR purposes is legal@lumenlingo.com.

Arbitration for United States Users

If you reside in the United States, any dispute that cannot be resolved through the informal resolution process above shall be resolved by binding individual arbitration rather than in court, except that you may assert claims in small claims court if your claims qualify. The arbitration shall be administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules.

You have the right to opt out of this arbitration clause within 30 days of first accepting these Terms by sending written notice to legal@lumenlingo.com. If you opt out, disputes will be resolved in the courts of England and Wales.

Class Action Waiver

To the maximum extent permitted by applicable law, you and Lumenshore agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. If this waiver is found to be unenforceable in your jurisdiction, the remaining provisions of this section continue in full force.

If you are a consumer in the European Union or the United Kingdom, nothing in this section affects your statutory rights, including the right to bring proceedings in the courts of your country of residence.

Nothing in this dispute resolution clause limits or restricts your right to bring a claim before a competent court for the infringement of your data protection rights under GDPR Article 79 or the Data Protection Act 2018, section 167. Data protection claims may always be brought before the courts regardless of any dispute resolution, arbitration, or class action waiver provisions in these Terms.

US Arbitration Agreement

If you are a resident of the United States, you and Lumenshore Limited agree to resolve any disputes through binding individual arbitration rather than in court, except as provided below.

Arbitration shall be administered by the American Arbitration Association (AAA) or JAMS under their Consumer Arbitration Rules. Proceedings may be conducted remotely, by written submissions, or in person at a location agreed by both parties. Each party shall bear its own attorneys' fees unless the arbitrator awards fees to the prevailing party.

The arbitrator's decision shall be final and binding, and may be entered as a judgment in any court of competent jurisdiction. The Federal Arbitration Act (9 U.S.C. §§ 1–16) governs the enforceability of this arbitration clause.

Class Action & Jury Trial Waiver

You and Lumenshore agree that each may bring claims against the other only in your or its individual capacity and not as a plaintiff or class member in any purported class, consolidated, or representative action.

You waive any right to a jury trial for any disputes not subject to arbitration. No claims of multiple users may be consolidated in a single proceeding.

30-Day Opt-Out Right

You may opt out of this arbitration agreement within 30 days of first accepting these Terms by sending written notice to legal@lumenlingo.com. If you opt out, you retain all other rights under these Terms.

Small Claims Court Exception

Either party may bring individual claims in a small claims court of competent jurisdiction, provided the claim qualifies under that court's rules.

Exceptions to Arbitration

Either party may seek injunctive or equitable relief in a court of competent jurisdiction for claims involving intellectual property infringement.

If the class action waiver above is found unenforceable, the entirety of this arbitration agreement shall be void. All other provisions of this arbitration clause are severable.

Enforcement & Remedies

LumenLingo’s content — including flashcard sets across 25 language pairs, grammar explanations, example sentences, and audio — constitutes a "literary work" and a protected "database" under the UK Copyright, Designs and Patents Act 1988 (CDPA) and the Copyright and Rights in Databases Regulations 1997. Lumenshore asserts its moral rights of attribution and the right against derogatory treatment in respect of all original content.

You acknowledge that any breach of the Intellectual Property, Content Protection, or Data Export sections of these Terms may cause irreparable harm to Lumenshore for which monetary damages would be inadequate. Accordingly:

• Lumenshore reserves the right to seek injunctive or other equitable relief in any court of competent jurisdiction, without the necessity of proving actual damages or posting a bond (to the extent permitted by applicable law)
• Lumenshore’s database right protection lasts 15 years from creation and is renewed with each substantial update to the content database
• These remedies are in addition to — and not in lieu of — any other rights or remedies available at law or in equity

Nothing in this section limits any rights or remedies that Lumenshore may have under applicable intellectual property, competition, or data-protection law.

Entire Agreement

These Terms, together with our Privacy Policy, End User Licence Agreement, and Cookie Policy, constitute the entire agreement between you and Lumenshore Limited regarding the Service.

This agreement supersedes all prior agreements, representations, and understandings between you and Lumenshore, whether written or oral.

No oral modification of these Terms shall be effective.

Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, that provision shall be severed from these Terms without affecting the validity and enforceability of the remaining provisions.

The court or arbitrator may reform the unenforceable provision to the minimum extent necessary to make it valid and enforceable.

Assignment

Lumenshore may assign or transfer these Terms, and any rights and licences granted hereunder, to any successor, affiliate, or acquirer of all or substantially all of its business or assets without your consent.

You may not assign or transfer your rights or obligations under these Terms without our prior written consent.

If we assign this agreement or any rights under it to a successor entity (for example, in connection with a merger, acquisition, or sale of assets), we will notify you by email or in-app notification within 30 days of the assignment taking effect. You will have the right to terminate your subscription within 30 days of such notification if you do not wish to continue under the new entity.

Waiver

The failure of Lumenshore to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision.

Any waiver of a breach of these Terms shall not constitute a waiver of any subsequent breach.

No waiver shall be effective unless made in writing and signed by an authorised representative of Lumenshore.

Relationship of the Parties

Nothing in these Terms shall be construed as creating an agency, partnership, joint venture, or employment relationship between you and Lumenshore.

Neither party has the authority to bind the other or to incur any obligation on behalf of the other.

Electronic Communications

By using the Service, you consent to receiving communications from us electronically, including by email, in-app notifications, and notices posted on our website.

You agree that all agreements, notices, disclosures, and other communications we provide to you electronically satisfy any legal requirement that such communications be in writing.

Headings

The section headings in these Terms are for convenience of reference only and shall not affect the interpretation or construction of these Terms.

Survival

Provisions of these Terms that by their nature should survive termination shall survive, including but not limited to: limitation of liability, indemnification, intellectual property ownership, dispute resolution, warranty disclaimers, and any accrued rights and obligations.

No Third-Party Beneficiaries

These Terms do not confer any rights on any person or entity that is not a party to these Terms.

No third party may enforce any provision of these Terms under the Contracts (Rights of Third Parties) Act 1999.

Notwithstanding the foregoing, Apple Inc. and its subsidiaries are intended third-party beneficiaries of these Terms solely to the extent required by Apple's Licensed Application End User Licence Agreement. Apple has the right to enforce these Terms against you as a third-party beneficiary to the minimum extent required by Apple's guidelines.

System Requirements

To use the LumenLingo iOS app, your device must meet the following minimum requirements:

• Operating system: iOS 26.0 or later
• Device: iPhone
• Internet connectivity: an active internet connection is required for initial setup, content downloads, authentication, and subscription management. Certain features (flashcard review of previously downloaded content) may be available offline.
• Storage: approximately 100 MB of free storage space for the app, plus additional space for downloaded content
• Account and Cloud Sync: a LumenLingo account and internet connection are required for cross-device Cloud Sync. When enabled, selected data is encrypted on-device and backed up to Lumenshore’s Rails-backed service and your private CloudKit container; the App can still use previously downloaded content without Cloud Sync.

To access the LumenLingo website, you need a modern web browser with JavaScript enabled (Chrome, Safari, Firefox, or Edge — current version or one version prior).

Consequences of Breach

If you breach any provision of these Terms, Lumenshore may, at its sole discretion:

• Suspend or terminate your access to the Service immediately and without prior notice;
• Withhold any refund for the remaining subscription period;
• Seek injunctive or equitable relief for intellectual property infringement or other violations of these Terms.

The remedies set out in this section are in addition to, and not in substitution for, any other remedies available to Lumenshore at law or in equity.

Right to Modify Service

Lumenshore reserves the right to modify, update, or discontinue any feature or content of the Service at any time without prior notice.

The addition or removal of language pairs, tiers, features, or content does not constitute a breach of these Terms.

We may change pricing for future subscription periods with reasonable notice. Any price changes will not affect your current subscription period.

Right to Suspend Service

We may suspend the Service temporarily for maintenance, security incidents, or operational needs.

Scheduled maintenance will be communicated when reasonably practicable.

We are not liable for any loss or damage arising from a temporary suspension of the Service.

Right to Terminate

Lumenshore may terminate or restrict your access to the Service in the following circumstances:

• Breach of these Terms;
• Fraudulent or abusive activity;
• Extended inactivity (after reasonable notice);
• At Lumenshore's sole discretion with reasonable notice.

You may terminate your use of the Service at any time by deleting your account and cancelling any active subscriptions.

Upon termination, your licence to use the Service is immediately revoked and your data will be deleted in accordance with our retention policy.

For curable breaches, we will notify you of the breach in writing and give you 14 days to remedy it. If the breach is not remedied within 14 days, we may then terminate your access to the Service. This cure period does not apply to breaches involving: illegal activity, fraud, harm to other users, or repeated violations of these Terms.

Right to Modify Terms

We may modify these Terms at any time by posting updated Terms on our website.

Material changes will be communicated via email (to subscribed users) or in-app notification.

Your continued use of the Service after notification constitutes acceptance of the modified Terms.

If you do not agree to the modified Terms, you must stop using the Service and cancel your subscription.

Non-material updates (such as typographical corrections or clarifications) may be made without notice.

If a modification to these Terms materially reduces your rights or increases your obligations, the change will not take effect for existing users until 30 days after notification. During that 30-day period, you may terminate your account and cancel your subscription free of charge if you do not agree to the modified Terms.

Effect of Termination

Accrued rights and obligations of both parties shall survive termination.

No refund will be issued for unused subscription periods upon user-initiated termination, except as required by applicable consumer protection law or Apple's refund policy.

If Lumenshore terminates your access without cause, you will receive a pro-rata refund for the unused portion of your current subscription period.

Your data will be deleted in accordance with the retention schedule described in our Privacy Policy.

Limitation Period for Claims

Subject to the exceptions below, any claim arising out of or relating to these Terms or the Service must be commenced within two (2) years after the date the claim arose or, if later, the date on which you became aware (or ought reasonably to have become aware) of the grounds for the claim.

This limitation period does not apply to claims for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; (c) any claim where a shorter limitation period would be unenforceable under applicable law.

This clause does not affect any statutory limitation periods that apply under the laws of your jurisdiction. In the United Kingdom, the Limitation Act 1980 provides a six-year limitation period for claims founded on breach of contract or tort, and nothing in these Terms shortens that period for consumers.

If you are a consumer in the European Union, the applicable limitation periods under your national law apply in full.

Refund & Cancellation Policy

iOS App Store Purchases

All subscription purchases made through the iOS app are processed and managed exclusively by Apple through the App Store.

Refund requests for App Store purchases must be directed to Apple at reportaproblem.apple.com. Lumenshore does not process payments and cannot issue refunds for any purchases made through the App Store.

Apple's refund policy governs all iOS subscription refunds. Lumenshore has no ability to override or modify Apple's refund decisions.

Cancellation

You may cancel your subscription at any time through your device's Settings > Apple ID > Subscriptions.

Cancellation takes effect at the end of your current billing period. You will retain access to all paid features until that period expires.

After the billing period ends, your account will automatically revert to the Free tier. Cancellation does not entitle you to a pro-rated refund for any remaining time in the current billing period.

Complimentary 14-Day Access

Every new customer receives 14 days of Royal-level access after account creation. No subscription is started and no payment is charged.

This complimentary access ends automatically and never converts or renews into a paid subscription. To start Royal later, you must separately tap Subscribe in the App and confirm the purchase with Apple.

EU/UK Cooling-Off Period

Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 (UK) and the EU Consumer Rights Directive, you have a 14-day right of withdrawal for distance contracts.

For digital content, this right of withdrawal may be waived if you: (a) consent to immediate performance of the service, AND (b) acknowledge that you will lose your right of withdrawal once digital content delivery begins.

If explicit consent is not obtained, your 14-day withdrawal right remains in full effect regardless of any use of the Service during that period.

Governing Law, Jurisdiction & Venue

Governing Law

These Terms and any dispute or claim arising out of or in connection with them or their subject matter or formation (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of England and Wales.

This choice of law applies regardless of your country of residence, domicile, or the country from which you access the Service, and notwithstanding any conflict of law principles that would otherwise apply.

Exclusive Jurisdiction

The courts of England and Wales shall have exclusive jurisdiction to settle any dispute arising out of or in connection with these Terms.

Where Section 18 (US Arbitration) of these Terms applies, the arbitration provisions shall govern instead of this jurisdiction clause.

Nothing in this section prevents either party from seeking interim or injunctive relief in any court of competent jurisdiction.

Venue

Any court proceedings shall be brought in the courts located in Leicester, England, or the High Court of Justice in London, at Lumenshore's election.

By using the Service, you consent to the personal jurisdiction of these courts and waive any objections to venue, including on the grounds of forum non conveniens.

Per-Jurisdiction Enforceability

If you are an EU consumer, nothing in this clause affects your right to bring proceedings in the courts of your domicile, as provided by the Brussels Regulation (recast).

If you are an Australian consumer, this jurisdiction clause does not restrict any rights you may have under the Australian Consumer Law to bring proceedings in Australian courts.

To the extent this clause is unenforceable in your jurisdiction, disputes shall be resolved in the courts that have jurisdiction under applicable law.

Language of Proceedings

All legal proceedings, arbitration, and communications relating to disputes shall be conducted in English.

The English language version of these Terms shall prevail over any translated version in the event of conflict.

Assumption of Risk

Educational Tool Acknowledgement

You acknowledge that LumenLingo is a supplementary language-learning tool, not a replacement for professional language instruction, accredited courses, or certified translation services.

Educational outcomes may vary depending on individual effort, prior knowledge, learning style, and other factors outside our control. You accept that results are not guaranteed and that the Service is provided as a general learning aid.

Limitation of Claims

To the maximum extent permitted by applicable law, you agree that your use of the Service is at your own risk and that Lumenshore's liability is limited as set out in the Limitation of Liability section of these Terms.

Statutory Protections

Nothing in this section excludes or limits your statutory rights under the Consumer Rights Act 2015, the EU Consumer Rights Directive, or any other applicable consumer protection legislation.

This section does not apply to claims for death or personal injury caused by Lumenshore's negligence, or for fraud or fraudulent misrepresentation.

Third-Party Content, Links & Services

Third-Party Links

The Service may contain links to third-party websites, applications, or services that are not owned or controlled by Lumenshore.

Lumenshore has no control over, and assumes no responsibility for, the content, privacy policies, or practices of any third-party websites or services. You acknowledge and agree that Lumenshore shall not be liable for any damage or loss caused by or in connection with use of or reliance on any such third-party content.

Inclusion of a link does not imply endorsement, affiliation, or sponsorship by Lumenshore.

Apple Platform

Apple Inc. is not a party to these Terms and has no obligation to provide maintenance, support, or warranty for the Service.

In the event of any failure of the Service to conform to applicable warranties, you may notify Apple, and Apple will refund the purchase price (if any). Apple has no other warranty obligation with respect to the Service.

Apple is not responsible for addressing any claims relating to the Service or your possession or use of the Service.

Apple is a third-party beneficiary of these Terms and, upon your acceptance, may enforce them against you.

Infrastructure Providers

Lumenshore is not liable for failures, outages, or breaches caused solely by third-party infrastructure providers beyond our reasonable control, including Apple (App Store and private CloudKit), Clerk and Google (authentication), RevenueCat (entitlements), Fly.io/PostgreSQL, Tigris, Upstash, Vercel, and Sentry.

Service availability depends on third-party infrastructure. Lumenshore does not guarantee the availability of third-party services.

User-Generated Content

If the Service permits user-generated content in the future, Lumenshore is not responsible for any content created, posted, or shared by users. Lumenshore does not endorse any user content and disclaims all liability arising from user content.

Third-Party Authentication

Authentication is provided through Clerk and may use Google Sign-In when you choose it. Lumenshore is not responsible for outages or security failures caused solely by those providers beyond our reasonable control; loss of access to the selected provider account may affect your ability to sign in.

Feedback & Submissions

IP Assignment

Any feedback, suggestions, ideas, feature requests, bug reports, or other communications you submit to Lumenshore ('Feedback') shall be deemed non-confidential and non-proprietary.

By submitting Feedback, you hereby irrevocably assign to Lumenshore all right, title, and interest in and to the Feedback, including all intellectual property rights therein.

You waive any and all moral rights in the Feedback to the fullest extent permitted by law.

No Obligation

Lumenshore is under no obligation to: (a) maintain any Feedback in confidence; (b) pay compensation for any Feedback; (c) respond to any Feedback; or (d) use or implement any Feedback.

Lumenshore may use, reproduce, distribute, modify, or create derivative works from Feedback for any purpose without attribution or compensation.

No Confidentiality

Do not submit any information you consider confidential or proprietary as Feedback.

Lumenshore has no confidentiality obligations with respect to any Feedback.

Representation & Warranty

You represent and warrant that you have the right to submit the Feedback and that the Feedback does not infringe any third party's intellectual property or other rights.

You agree to indemnify Lumenshore against any claims arising from your Feedback.

Pre-Suit Notice & Mandatory Negotiation

Notice Requirement

Before commencing any legal proceeding or arbitration against Lumenshore, you must first send a written Notice of Dispute ('Notice') to Lumenshore at legal@lumenlingo.com and by post to the registered office at Windsor House, Troon Way Business Centre, Humberstone Lane, Leicester, England, LE4 9HA.

The Notice must include: your full legal name, the email address associated with the Service, a detailed description of the claim, the specific Terms provision allegedly breached, the specific relief sought, and your signature or electronic equivalent.

Mandatory Negotiation Period

After receiving your Notice, the parties shall engage in good faith negotiations for a period of sixty (60) days before either party may commence legal proceedings or arbitration.

Lumenshore shall acknowledge receipt of your Notice within fourteen (14) days.

During the negotiation period, both parties agree not to commence any legal proceeding. The negotiation period may be extended by mutual written agreement.

Consequence of Non-Compliance

Any legal proceeding or arbitration commenced without complying with this notice and negotiation requirement shall be dismissed without prejudice, with costs awarded to Lumenshore.

Failure to provide proper Notice constitutes a material breach of these Terms by the claimant.

Exceptions

The notice and negotiation requirement does not apply to: (a) intellectual property infringement claims by either party; (b) claims for injunctive or equitable relief to prevent imminent, irreparable harm; or (c) claims in small claims court, if qualifying.

Tolling

The limitation period shall be tolled during the mandatory negotiation period.

Sending a compliant Notice preserves your claim within the limitation period.

Sole & Exclusive Remedy

Service Dissatisfaction

YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY DISSATISFACTION WITH THE SERVICE IS TO STOP USING THE SERVICE AND CANCEL YOUR SUBSCRIPTION.

If you are dissatisfied with any content, features, or policies, your only recourse is to discontinue use.

You may also: (a) request deletion of your account and data per our Privacy Policy, and (b) request a data export per GDPR Article 20.

Service Failures

In the event of any failure, error, or defect in the Service, your sole remedy (to the maximum extent permitted by law) is for Lumenshore to use commercially reasonable efforts to correct the issue within a reasonable timeframe.

If Lumenshore is unable to correct the issue, your sole remedy for paid subscribers is a pro-rata refund of the subscription fee for the affected period, not to exceed the total amount paid in the preceding twelve (12) months.

For Free tier users, your sole remedy is discontinuation of use.

No Specific Performance

You agree that you are not entitled to specific performance or injunctive relief requiring Lumenshore to provide any particular feature, content, language pair, or service level.

Lumenshore's obligations under these Terms are limited to commercially reasonable efforts.

Cumulative Remedies for Lumenshore

Lumenshore's rights and remedies under these Terms are cumulative and not exclusive of any other rights or remedies available at law or in equity.

Lumenshore's election to exercise one remedy does not waive any other remedy.

Consumer Rights Preservation

This clause does not affect your statutory rights under the Consumer Rights Act 2015 (UK), including rights to repair, replacement, or price reduction for faulty digital content.

EU consumers retain all rights under the EU Consumer Rights Directive.

Data Loss, Service Interruption & Force Majeure

Data Loss Disclaimer

LUMENSHORE IS NOT LIABLE FOR ANY LOSS, CORRUPTION, OR DELETION OF USER DATA, INCLUDING BUT NOT LIMITED TO: learning progress, game scores, XP, streaks, mastered content, favourites, language preferences, tier selections, or any other user-generated or user-stored data.

Data loss may occur because of app or operating-system updates, device changes, local database migration errors, cache clearing, account deletion, or failures affecting the device-encrypted Rails or private CloudKit backup paths.

Users are solely responsible for maintaining backups of any data they consider important.

Lumenshore provides data export functionality (GDPR Article 20) as a courtesy; however, failure of the export function does not create liability.

Service Interruption

Lumenshore does not guarantee continuous, uninterrupted, or error-free operation of the Service.

The Service may be unavailable due to: scheduled maintenance, emergency maintenance, third-party outages, DDoS attacks, software bugs, or other operational issues.

Lumenshore is not liable for any loss arising from temporary or permanent unavailability of the Service.

No Service Level Agreement (SLA) is provided unless separately agreed in writing.

Force Majeure

Lumenshore shall not be liable for any failure or delay in performance arising from causes beyond its reasonable control ('Force Majeure Events').

Force Majeure Events include but are not limited to: acts of God, fire, flood, earthquake, epidemic, pandemic, war, terrorism, civil unrest, sanctions, government orders, strikes, labour disputes, Internet service failures, cloud service provider outages, DDoS or cyber attacks, power failures, telecommunications failures, Apple App Store policy changes or outages, changes in law or regulation, and third-party service provider failures.

During a Force Majeure Event, Lumenshore's obligations are suspended for the duration of the event.

If a Force Majeure Event continues for more than ninety (90) consecutive days, either party may terminate the agreement with no liability to the other.

App Updates & Migration

App updates may cause changes to features, UI, content, or data structures.

Lumenshore is not liable for any adverse effects of app updates including: loss of settings, progress reset, feature removal, or incompatibility with your device or OS version.

Continued use after an update constitutes acceptance of the updated Service.

Cloud Synchronisation

Optional Cloud Sync encrypts selected learning data on your device and replicates ciphertext to Lumenshore’s Rails-backed cloud service and your private CloudKit container. Provider terms and availability also apply.

Lumenshore does not guarantee uninterrupted synchronisation or restoration and is not liable for failures, conflicts, delays, or losses beyond its reasonable control, subject always to rights that cannot lawfully be excluded.

If you disable Cloud Sync, new learning changes remain local to the device. Existing server-side encrypted envelopes and private CloudKit copies follow the deletion controls and retention rules in our Privacy Policy.

No Fiduciary Duty

Nothing in these Terms or your use of the Service creates any fiduciary duty, trust, or special relationship between Lumenshore and you.

Lumenshore acts solely as a licensor of digital content and owes no duty of care beyond what is expressly stated in these Terms and required by applicable law.

Service Discontinuation, Business Transfer & Wind-Down

Right to Discontinue

Lumenshore reserves the right to discontinue, permanently shut down, or cease operating the Service (in whole or in part) at any time, for any reason or no reason.

If Lumenshore elects to discontinue the Service, we will provide at least 30 days' notice via email (if available) and/or in-app notification.

During the notice period, paid subscribers may export their data using the built-in export functionality.

After the discontinuation date, all user accounts and associated data will be deleted in accordance with our data retention policy.

Liability Cap on Discontinuation

Lumenshore's sole liability for discontinuation of the Service is a pro-rata refund of the unused portion of any pre-paid subscription fee.

Lumenshore is not liable for any indirect, incidental, consequential, or special damages arising from discontinuation, including but not limited to: loss of learning progress, loss of data, loss of streaks, loss of achievement records, or inability to continue a learning programme.

Free tier users have no right to any compensation upon discontinuation.

Business Transfer & Assignment

Lumenshore may assign, transfer, or novate these Terms and all rights and obligations hereunder to any successor, acquirer, or assignee in connection with a merger, acquisition, reorganisation, sale of assets, or change of control, without your prior consent.

In such event, the assignee shall assume all rights and obligations under these Terms.

You will be notified of the assignment within 30 days, but your continued use of the Service after assignment constitutes acceptance.

The assignment shall not, by itself, reduce your rights under these Terms.

Wind-Down & Insolvency

In the event that Lumenshore enters administration, liquidation, or any insolvency proceeding, these Terms shall terminate automatically.

Any claims by users shall rank as unsecured claims in accordance with applicable insolvency law (Insolvency Act 1986).

Directors and officers of Lumenshore shall have no personal liability for the company's obligations under these Terms (subject to applicable law).

No Guaranteed Minimum Service Period

Lumenshore does not guarantee any minimum period of service availability.

Your subscription entitles you to access the Service if and while it is available; it does not create a guarantee of perpetual or long-term service.

Content Removal Rights

Lumenshore may remove, modify, or discontinue specific features, language pairs, content categories, or learning materials at any time without prior notice.

The removal of any specific content does not entitle you to a refund or constitute a breach of these Terms.

Lumenshore is under no obligation to maintain, update, or expand the content library.

Survival Post-Discontinuation

The following clauses survive discontinuation of the Service: limitation of liability, indemnification, intellectual property ownership, dispute resolution, governing law, aggregate data rights, feedback IP assignment, and the no-warranty disclaimer.

Regulatory & Compliance

Regulatory Changes

We reserve the right to modify the Service or these Terms to comply with changes in applicable laws, regulations, or platform requirements. Where practical, we will provide advance notice of material changes.

If a regulatory change materially affects your use of the Service, you may cancel your subscription before the change takes effect without penalty.

We shall not be liable for any unavailability or feature changes required by law or regulation.

Geographic Restrictions

The Service is intended for users worldwide, but certain features may not be available in all jurisdictions due to legal, licensing, or platform restrictions.

You are responsible for ensuring that your use of the Service complies with the laws of your jurisdiction.

We may restrict access to the Service or certain features in specific regions without prior notice if required by law.

Apple App Store Policies

All in-app purchases and subscriptions are processed exclusively through Apple's App Store. Apple acts as the merchant of record for all transactions and is responsible for payment processing, billing, and tax collection.

By purchasing a subscription, you agree to Apple's terms and conditions in addition to these Terms. In the event of any conflict between these Terms and Apple's policies regarding payment processing, Apple's policies shall prevail.

We do not have access to your payment information. For billing enquiries, refund requests, or payment disputes, please contact Apple Support directly.

Tax & VAT Compliance

Prices displayed on our website are shown in British Pounds (GBP) and include UK Value Added Tax (VAT) at the standard rate of 20%. Lumenshore Limited is registered for VAT in the United Kingdom (VAT Registration Number: GB 270411929). The actual price you are charged may differ based on your country, local tax rates, and the currency used by Apple in your region.

For in-app purchases, Apple is the merchant of record and is responsible for calculating, collecting, and remitting all applicable taxes, including VAT, GST, and sales tax, in accordance with local laws. Apple applies the EU VAT One Stop Shop (OSS) rules for EU customers and handles tax compliance for all other jurisdictions. We do not separately collect or remit taxes on subscription payments.

Data Protection & Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect your personal data in accordance with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.

We process personal data only as necessary to provide the Service, comply with legal obligations, and improve the user experience. You have the right to access, rectify, erase, or port your data as described in our Privacy Policy.

Regulatory Indemnification

You agree to indemnify and hold harmless Lumenshore Limited from any claims, losses, or expenses arising from your breach of applicable laws or regulations while using the Service.

This indemnification obligation survives termination of your account or these Terms.

Account Security & Single-User License

Single-User License

Each subscription is a personal, non-transferable, single-user license.

Your subscription may be used only by you, the individual who purchased or activated the subscription.

You may use the Service on multiple devices owned or controlled by you, but you may not allow any other person to use your account.

Prohibition on Credential Sharing

You may not share your LumenLingo, Google, Clerk, or other authentication credentials, passwords, or session tokens with any other person.

You may not allow simultaneous use of your account on devices used by different individuals.

Account sharing detected by Lumenshore may result in immediate account suspension or termination without refund.

User Responsibility for Account Security

You are solely responsible for maintaining the confidentiality and security of your account credentials.

You are responsible for all activity that occurs under your account, whether or not authorised by you.

You must immediately notify Lumenshore (legal@lumenlingo.com) of any unauthorised access to or use of your account.

Lumenshore is not liable for any loss arising from unauthorised access to your account where such access resulted from your failure to maintain account security.

Family Sharing

Apple Family Sharing, where available and supported, is the only authorised method of sharing access to the Service with other members of your household.

Family Sharing requires each family member to use their own Apple ID.

Any sharing arrangement outside of Apple Family Sharing constitutes credential sharing and is prohibited.

Institutional & Educational Use

LumenLingo subscriptions are for individual, personal use only.

Use of LumenLingo in educational institutions, corporate training programmes, or commercial settings requires a separate institutional license agreement from Lumenshore.

Institutions may not purchase individual subscriptions in bulk as a substitute for an institutional license.

Enforcement Measures

Lumenshore may employ technical measures to detect and prevent account sharing, including device fingerprinting, concurrent session detection, and usage pattern analysis.

Detection of account sharing constitutes breach of these Terms and entitles Lumenshore to suspend or terminate the account.

Waiver of Class, Collective & Representative Proceedings (Non-US)

UK Group Litigation Waiver

To the maximum extent permitted by law, you waive any right to participate in a Group Litigation Order (GLO) under the Civil Procedure Rules (CPR 19.III) against Lumenshore.

This waiver may not be enforced where it is prohibited by applicable UK consumer protection law, including the Consumer Rights Act 2015.

EU Representative Actions Directive Waiver

To the maximum extent permitted by applicable law, you waive the right to participate in representative actions brought by qualified entities under the EU Representative Actions Directive (2020/1828) or its national implementations.

This waiver applies to collective actions for injunctive measures and redress measures, to the extent permissible under the laws of your jurisdiction.

Global Collective Action Waiver

In jurisdictions outside the US, UK, and EU, you agree that any dispute will be resolved individually and not as part of any class, collective, or group proceeding.

This includes but is not limited to Australian class actions (Federal Court Rules Part 9.33), Canadian class proceedings, Brazilian collective actions (LGPD Art. 42), and any similar aggregated or representative proceeding.

Exceptions — Mandatory Collective Proceedings

This waiver does not apply where: (a) applicable law expressly prohibits waiver of collective proceedings rights; (b) a court of competent jurisdiction invalidates the waiver; or (c) a regulatory body initiates proceedings on behalf of consumers.

Where the collective action waiver is found unenforceable in a jurisdiction, the remaining Terms continue in full force.

Regulatory enforcement actions and government-initiated proceedings are not affected by this clause.

Enforceability Notice

The enforceability of class, collective, and representative action waivers varies by jurisdiction. In some jurisdictions (including Germany under AGB law, France regarding CNIL collective actions, and Australia), such waivers may be unenforceable.

All waivers in this section are subject to the qualifier 'to the maximum extent permitted by applicable law' and are severable.

Individual Dispute Resolution

Any claim you may have against Lumenshore must be brought within the applicable limitation period and must follow the pre-suit notice and dispute resolution procedures set out elsewhere in these Terms.

Individual dispute resolution through negotiation, mediation, and where applicable arbitration or court proceedings, is the intended pathway for resolving any claims.

Apple Licensed Application EULA

To the extent required by Apple’s App Store terms, this agreement incorporates by reference Apple’s Licensed Application End User License Agreement, available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/.

In the event of a conflict between these Terms and Apple’s Licensed Application EULA, Apple’s EULA shall prevail to the extent of the conflict, but only in respect of matters within Apple’s EULA’s scope.

Accessibility

We are committed to making LumenLingo accessible to all users. We strive to comply with the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA for our website and follow Apple’s Human Interface Guidelines for accessibility in our iOS app. For details, please see our Accessibility Statement.

If you encounter any accessibility barriers, please contact us at legal@lumenlingo.com. We recognise our obligations under the Equality Act 2010 to make reasonable adjustments and will endeavour to address any reported issues promptly.

Online Safety Act 2023

LumenLingo does not currently permit users to generate, upload, or share content with other users. All flashcard content is provided by Lumenshore and all learning data remains private to each individual user.

Because there is no user-generated content, the duties in Part 3 of the Online Safety Act 2023 relating to user-to-user services (including section 10, illegal content duties) do not currently apply to LumenLingo.

If we introduce features that allow users to create or share content with other users in the future, we will update these Terms to include content moderation commitments, a reporting mechanism, review timelines, and an appeals process in accordance with the Online Safety Act 2023.

Service Classification

LumenLingo is a language learning application that delivers proprietary educational content (flashcards, grammar explanations, phrases, and audio) directly to users. Lumenshore is the publisher of all content within the Service.

LumenLingo does not currently host, store, or transmit user-generated content. There are no comments, forums, user profiles, or social features. As such, LumenLingo does not operate as an intermediary service within the meaning of DSA Art. 3.

If user-generated content features are introduced in the future, Lumenshore will implement the full notice-and-action obligations required by the DSA.

DSA Compliance Statement

Lumenshore Limited is committed to compliance with the Digital Services Act (EU Regulation 2022/2065) as applicable to the Service.

As LumenLingo does not qualify as an intermediary service, hosting service, or online platform under the DSA, the majority of DSA obligations (including the notice-and-action mechanism under Art. 16 and transparency reporting under Art. 15) do not currently apply.

Lumenshore monitors regulatory developments and will update its compliance measures if the scope of DSA applicability changes due to new features or regulatory guidance.

Changes to These Terms

We may update these Terms from time to time. When we make significant changes, we'll update the "Last updated" date and version number at the top of this page and may notify you through the App.
