Quick answers, before you write.
How do I cancel my subscription?
Subscriptions are managed by Apple, Google, or Microsoft, depending on where you bought it. On iOS: Settings → Apple ID → Subscriptions. On Android: Play Store → Profile → Payments & subscriptions. Cancellation takes effect at the end of your billing period.
Can I get a refund?
Refunds are handled by the store you bought from. We can’t process refunds directly, but we’re happy to help you submit a request — just write to us.
I bought premium on iOS. Does it work on Android?
Premium is tied to the platform you bought it on. If you switch platforms, we can usually help with a courtesy unlock — write to us with your receipt and we’ll sort it.
I lost my study progress. Can you restore it?
Because the app stores your progress only on your device (no account, by design), we don’t hold a backup. On iOS, restoring an iCloud backup of the device usually brings your progress back; on Android, the same applies for Google Drive backups.
I found a translation error or wrong answer.
Please tell us — these reports genuinely improve the app. Include the question text and the language, and we’ll fix it in the next content update.
Will you support more apps / languages?
Yes, that’s the plan. New languages and new apps are coming. If you’d like to be the first to know, just say so when you write in.
