To run the leaderboards and improve the game, we store: your chosen player name, an anonymous device identifier, your country (from your browser's language, for the leaderboard flag), and anonymous play statistics such as waves reached, session length and error reports.

No real name, email address, or precise location is collected in normal play, and nothing is sold or shared with third parties. Feedback you submit is stored so we can act on it.

On the web version, signing in (Google / Discord / Apple) is optional; it stores only the account identifier and email needed to sync your progress across devices. Platform builds (e.g. CrazyGames) offer no sign-in and collect no account data.
