Data deletion

Mazhobe Mahjong (developer Stepan Zotov) keeps on its server only the data tied to an anonymous player identifier. There is no account, so it is this data that gets deleted.

How to request deletion

1. Open the game: the player identifier is shown at the bottom of the main screen (the “ID: …” line); tapping it copies the identifier and the deletion code to the clipboard.
2. E-mail stepanz.dev@gmail.com with the subject “Data deletion” and paste what was copied. Other players can see the identifier in the leaderboard, the code only you: we do not delete without it, so nobody can delete someone else's data. Game versions without the code (before 1.0.5) copy only the identifier — then we will ask you to confirm the data is yours.
3. The data is deleted within 30 days; you get a reply to the same e-mail.

What is deleted

• the player identifier and everything tied to it: progress, moves of an unfinished game, hint balance, statistics and scores;
• nickname and avatar, leaderboard rows, likes;
• the link to your Google Play Games account (the Google account itself and Play Games achievements stay with Google, under your control);
• acorns and in-game shop purchases paid with acorns.

What is kept

• technical server logs with request IP addresses (lines about two-player games and received logs also carry the identifier) — purged automatically within 30 days;
• the copy of the game on your device: the local save goes away with the app.
