Account & Data Deletion — CheckMate Chess
Last updated: 6 August 2026
CheckMate Chess is a single-player, offline chess puzzle game. An account is optional and exists only to back up your progress. This page explains how to delete that account, exactly what is removed, and what stays.
What we hold
If you never create an account, nothing about you reaches our servers — the game runs entirely on your device.
If you do create one, we hold:
- Your email address, as the account identifier.
- A cloud backup of your progress: levels solved, stars, streaks, badges, rating, and your heart / token balance.
- Anonymous usage statistics — which mode was opened, how many puzzles were solved — tagged with a random per-install identifier. Board positions, the content of your moves, and anything you write to us are never part of these statistics.
Delete from inside the app (recommended)
- Open CheckMate Chess and go to your account screen.
- Tap Delete my account, below Sign out.
- A confirmation screen lists what will be removed and what will stay.
- Confirm your identity with biometrics (Face ID / fingerprint) or your password.
Deletion happens immediately. There is no waiting period and it cannot be undone.
What is deleted, what is kept
| Data | What happens |
|---|---|
| Your account and email address | Permanently deleted. |
| Cloud backup of your progress | Permanently deleted. |
| Anonymous usage statistics | Unlinked from you. The records stay in aggregate counts, but the reference to your account is erased, so they can no longer be connected to you. |
| Progress on your phone | Kept by default — deleting your account does not delete your game. See below. |
You can create a new account with the same email address at any time. Deleting an account does not block the address.
Progress on your device
Your levels, stars and rating live on the phone itself, and they stay there after the account is gone. If you want that erased too, tick “Also delete progress on this device” on the deletion screen. The same reset is available at any time from Settings → Reset progress.
Uninstalling the app removes the data on your device, but it does not delete your account — use the in-app option, or write to us.
Retention
There is no retention period for a deleted account: the account record and the cloud backup are removed at the moment you ask. De-identified usage statistics are kept indefinitely in aggregate form.
If you cannot reach the app
If you have already uninstalled the app or cannot sign in, write to us from the email address of the account:
