Delete my data

Mahjong Axions, by AxionsLab inc. The game has no sign-up: your online account is anonymous, identified by a randomly drawn player identifier. What gets erased is described in detail in the privacy policy: https://axionslab.io/games/mahjong-axions/privacy.

If the game is installed. Settings → Delete my data, then confirm. The game erases its save and technical log on the device, asks our server to erase everything carrying your identifier — account, nickname, games, league group places — and resets the device's Firebase analytics data. Without a network, the request is sent again at every launch until the server confirms it.

If you uninstalled the game. Write to contact@axionslab.io, subject "Delete my data", with your player identifier and your deletion code — both shown in Settings → About. The code proves the request really comes from you: the identifier is visible in leaderboards, so it is not enough on its own. We erase everything carrying the identifier on our server within 30 days at most, and reply once it is done.

If you did not note them. Without identifier and code, nobody can prove the account is theirs — neither you, nor someone who would like to erase another player's account. The account holds no name, no contact details, no device identifier, and it is erased automatically twelve months after its last game. If you still have the game on another device, or Google backup restored it, the identifier shown is the current account's; an older device had its own.

What remains elsewhere. Analytics data and crash reports already sent to Google are erased according to its retention periods (fourteen months for identifier-level analytics). The Android backup copy, if backup is on, lives in your Google account: you can delete it from there.

Before writing to us

My progress is gone. It is stored on your device and we hold no copy — so we cannot restore it. On Android, if automatic backup to your Google account was on, it comes back by itself when you reinstall the game with that account. Otherwise, uninstalling, changing device, or clearing the game's data loses it permanently.

I want to change my nickname. Profile screen, by tapping your name.

A nickname is offensive or inappropriate. Write to us with the nickname as it appears on the leaderboard. We can erase it: its owner then gets the default name back.

I want to change my advertising choice. Settings → Ad preferences (shown where the law requires consent, notably in Europe).

I don't want notifications any more. Turn them off in your device settings, under the app.

A video failed but I want my reward. You already have it: the game grants the reward even when a video fails. That failure is our problem, not yours.

The game is in the wrong language. Settings → Language.

Is a level impossible? No. Every level is generated with a guaranteed solution and verified automatically before shipping. If no move remains, shuffling produces one.

Reporting a problem

Tell us your device model, its Android version, the level number, and what you did just before. A screenshot helps a lot.
