Privacy

The active game, local statistics, and preferences stay on the device for offline play. Creating an account is optional.

Data we process

• Account: email address, user identifier, and nickname.
• Activity: progress, results, streaks, rewards, cosmetics, and private rooms.
• Purchases: transaction identifier, purchased pack, delivered Stars, and refund state. Apple or Google processes payment; Nanmen never receives card numbers.

Use and providers

We use this data only to authenticate, sync, deliver purchases, prevent duplicates, and provide requested features. Supabase hosts accounts and progress; Resend delivers recovery emails; Apple and Google process purchases. We do not sell data, show ads, or track users across apps or websites.

Retention and deletion

Local data remains until the app or its data is removed. Account, progress, and purchase records remain while the account exists; transaction records may be retained for the minimum period required for fraud prevention, refunds, and legal obligations. Permanent deletion starts from Your account inside the app and deletes the account, profile, and cloud progress. See Delete account.
