Question 1

How do I get started with LumenLingo?

Accepted Answer

Download LumenLingo free from the App Store, pick your languages, and start learning. The Free tier gives you 3 language pairs, all 3 practice modes, and 30 minutes of daily practice. No sign-up or credit card needed.

Question 2

What languages are available?

Accepted Answer

LumenLingo supports 9 languages: English, Spanish, French, German, Japanese, Chinese (Mandarin), Arabic, Polish, and Ukrainian. That makes 25+ two-way pairs. Free users get 3 pairs; Pro unlocks 7; Elite/Royal unlocks all 25+.

Question 3

How do membership tiers work?

Accepted Answer

There are four tiers: Free, Pro (£9.99/mo), Elite (£19.99/mo), and Royal (£99.99/mo). Each tier adds more language pairs, background sounds, visual backgrounds, and features. Start free and upgrade whenever you are ready.

Question 4

How do I upgrade my subscription?

Accepted Answer

Open LumenLingo, go to the Membership screen, and tap the tier you want. Your purchase is handled through the Apple App Store. Upgrades take effect immediately.

Question 5

Can I use LumenLingo offline?

Accepted Answer

Yes. Offline mode is available on Pro and above. Your flashcard decks and practice content download to your device so you can study anywhere. Progress syncs when you reconnect.

Question 6

What are background sounds and breathing exercises?

Accepted Answer

Background sounds are audio scenes — like a Paris cafe, ocean waves, or deep space — that help you focus while studying. Breathing exercises show a calming animated circle that grows and shrinks as you breathe, helping you relax between sessions.

Question 7

How does the timed review system work?

Accepted Answer

LumenLingo schedules reviews based on how well you know each word. Words you find easy appear less often. Words you struggle with come back sooner. Over time, this helps you remember more with less effort.

Question 8

How do I cancel my subscription?

Accepted Answer

Cancel anytime with no penalties. On your iPhone: Settings > Apple ID > Subscriptions > LumenLingo > Cancel. You keep access until the end of your billing period. Your progress is always saved.

Question 9

Is my data synced across devices?

Accepted Answer

LumenLingo uses iCloud to sync your progress, streaks, and settings across Apple devices signed in to the same Apple ID. Your data stays on Apple’s servers — we do not store your learning data on our own servers.

Question 10

How do I delete my data?

Accepted Answer

In the app, go to Settings > Reset Progress to clear all data. Since everything is stored on your device and iCloud, no server-side deletion is needed. Email us at {{EMAIL:support}} if you need help.

Question 11

What practice modes are available?

Accepted Answer

Three modes: Flashcards for vocabulary, Grammar Quizzes for sentence skills, and Word Builder for spelling words letter by letter. Each has Beginner, Intermediate, and Advanced levels.

Question 12

Do I lose my progress if I downgrade?

Accepted Answer

No. Your progress, streaks, points, and study data are always saved. If you downgrade, some paid features are locked, but your learning history stays. Upgrade again anytime to pick up where you left off.

Question 13

How do I export my data?

Accepted Answer

Your data lives on your device and iCloud. You can see your progress in the app. For a copy of any personal data we hold, submit a request through our Data Request page or email {{EMAIL:support}}. We reply within 30 days.

Question 14

What data does LumenLingo collect?

Accepted Answer

Very little. The app stores learning data on your device and syncs via iCloud — we cannot see it. The website uses anonymous analytics (Vercel), error reports (Sentry), and stores newsletter sign-ups if you opt in. We do not track you, sell data, or use ad cookies.
