Your data and deletion
No online account
Block Puzzle does not create an online account. The profile name and avatar are local game preferences, not a sign-in.
Delete local progress
On Android, open Settings → Apps → Block Puzzle → Storage → Clear data (the names vary by phone). This removes saved games, scores, streaks, rewards, your local profile and settings. Uninstalling also removes app-local data. These actions cannot be undone unless you kept a backup.
Delete backup files
Use your Files app to delete block-puzzle-backup.json and any copies you made. If you saved a file in Drive or another cloud provider, delete it there and empty its trash if you want it removed there too. Clearing app data does not delete exported files.
Stop reminders
Turn off Daily reminder in the app’s Settings, or disable notifications for Block Puzzle in Android settings.
Delete support correspondence
Email classhai.ofc@gmail.com from the address you used to contact us and describe your request. Do not send passwords, identity documents or the contents of your phone. We cannot remotely erase a local save because we do not have access to it.
