Answers to the questions we get most often. If something is missing, write to us.
Restore a purchase
- Open VIP in the app and use Restore purchase; the server then re-checks your account with the store.
- The 30-day pass cannot be re-listed by the store, so it is restored from your account history instead.
Manage or cancel your subscription
- Subscriptions are managed by Google Play: use Manage subscription in VIP, or the Play Store's subscriptions page.
- Cancelling stops the next renewal; the period you already paid for still works.
Delete your account
- In the app: Settings, then Delete account. On the web: use the delete account page on this site.
- Deleting your account does not cancel your Google Play subscription.
Why do cards repeat?
- We send unseen cards first and only add already-seen cards when you have seen almost everything in a course.
- Once every card of a course has been played, that course starts a new cycle.
Why can't I start a new round offline?
- The deck is fetched once when a round starts and then works offline; a new round needs a connection to check access and pick unseen cards.
Still stuck?
- Write to zhexin233@gmail.com and tell us your app version and what you were doing.
