This policy covers the Chessball mobile app (com.mcgames.chessball), made by MC Stud.io.
If you sign in, we store your account ID, display name and — with Google sign-in — your email address. If you play online, the server records the result of each match against your account ID. If you turn notifications on, we store a device token so we can tell you when it is your turn. Your settings stay on this device.
To run online matches, to show your statistics and the weekly leaderboard, and to send the “your turn” notification you asked for. Nothing else.
Your display name is visible to opponents and spectators, and on the weekly leaderboard. Accounts, match records and notifications are handled by Google Firebase on our behalf. We do not sell your data, and there is no advertising or third-party analytics in this app.
You can play offline without an account. You can turn notifications off at any time in Settings, which also removes this device’s token. To delete your account and the match records attached to it, contact us at the address below — see the account deletion page for the details.
Team and piece names you enter, and your display name, are visible to other players on the weekly leaderboards. You can report an offensive name from any leaderboard row (long-press); reports are reviewed manually, and offensive names may be masked or reset. Names the game generates for teams and pieces are fictional wordplay — any resemblance to real persons is coincidental.
Chessball is not directed at children under 13, and we do not knowingly collect their data.
