Game data and privacy

The game works offline without ads, purchases or an account. It includes no advertising or analytics SDK and does not send game progress to an operator server.

Best score, tutorial, language and wave preparation checkpoints are saved on your device. Deleting the app deletes local saves. OS backups and diagnostics follow your Apple settings.

Support emails and messages are used to answer requests and resolve issues, then deleted when no longer needed except where retention is required by law. Contact the email below to request access, correction or deletion of inquiry data.

Policy changes will be posted here with an updated effective date. Effective: 11 September 2026.
