Open the app and go to Profile → Delete account. Deletion is immediate and permanent — your stats, streak, subscription binding, and account record are erased. This cannot be undone.
If you reinstall the app or switch devices, sign in with the same account and tap Profile → Restore purchase. Your subscription will re-sync automatically.
Subscriptions are managed by Apple or Google, not by us. On iOS, go to Settings → Apple ID → Subscriptions. On Android, open the Google Play Store → Profile → Payments & subscriptions. Cancel at least 24 hours before the renewal date to avoid being charged.
If you previously signed in (email, Apple, or Google), your stats and streak are backed up — just sign in again on the new device. If you played without an account, progress is local to that device and cannot be recovered once the app is removed.
The daily puzzle downloads once and can be played offline. The Atlas of Time, archive, sign-in sync, and ads all require a connection. A subscription removes the ads — but not the connection requirement for archive access.
