Account and data deletion
App: Chessllenge (Android & iOS) · Developer contact: muhammedariforhan@gmail.com
You can permanently delete your Chessllenge account and all data attached to it. There are two routes; both have the same result.
Route 1 — In the app (recommended, immediate)
- Open the app and go to the Profile tab in the bottom navigation.
- Scroll to the Danger zone card at the bottom of the page.
- Tap Delete account.
- Type
DELETEin the confirmation box and confirm.
Deletion is immediate and cannot be undone. Your recovery code stops working; the account cannot be reached again.
Route 2 — If you can't reach the app (email)
If you lost your phone or cannot open the app, send us your recovery code (or your player ID) at:
muhammedariforhan@gmail.com — with “Account Deletion” as the subject.
Because we hold nothing else that identifies you (we store no name, email or phone number), a request can only be verified with the recovery code or player ID. Requests are completed within 30 days at the latest and we confirm the outcome in writing.
Data that is deleted
When the account is deleted, all of the following is permanently removed:
- Your identity: player ID, username, recovery code hash
- Your ratings in every format (Bullet, Blitz, Rapid) and your rank
- Daily quest and achievement progress
- Coin balance and cosmetic ownership
- Puzzle rating and solve history
- Follow and friend relationships
- Tournament entries and season records
Games in progress are treated as abandoned.
Data that is retained, and why
The result records of games you played remain in your opponents' game history — but your identity is removed and you appear as “Deleted player”. You cannot be contacted or identified through those records.
The reason: your opponents' game history and Glicko-2 rating calculations are based on those games. Erasing the records entirely would corrupt other players' ratings and histories.
Retention period
In-app deletion has no waiting period; the data is removed from the server immediately. Requests sent by email are completed within 30 days. Copies held in backups roll out of the backup cycle within 30 days at the latest.
