Privacy Policy

Last updated 1 November 2026

Messy Mahjong is a game. We don't show ads, we don't sell data, and we don't track you across other apps or websites.

On your phone

Your name, avatar, settings, progress and favourite hands are stored on your phone. Deleting the app deletes them.

When you play online

To run online tables and chat, the app sends our game server your display name, your avatar, a player code (made on your phone; it isn't your device's or Apple's identifier), the moves you make and any chat messages you send. The server keeps this only in memory while it's needed: a table is cleared after it goes quiet, and "online now" fades after 90 seconds. Chat is not saved, and none of this is shared with anyone except the other players at your table.

Accounts and friends (optional)

Friends need an account. If you sign in with Apple, Google or Facebook, our server stores an account with that service's sign-in identifier for you (not your email or password; for Apple, also the token we need to cancel that sign-in when you delete your account), your display name and avatar, your friend code, your friends and your pending friend requests, and your leaderboard points and time played. Your friends see your name, avatar and whether you're online; the leaderboards show your name, avatar, points and time played to other players. If you turn on notifications, we also keep your phone's notification token so we can tell you about table invites and friend requests; it is removed when you sign out or delete your account. Tap Delete account in the app to erase all of it straight away; we also revoke the app's Sign in with Apple access. Facebook's own use of data is covered by Facebook's privacy policy.

Purchases

Tile sets, mats and racks are bought through Apple. We never see your payment details. On Android, Google Play purchase receipts are sent to our server to confirm the purchase with Google and to handle refunds.

Children

We don't knowingly collect personal information from children under 13 beyond the display name and chat described above.
