GREYSWARM is a free browser game. We keep data collection to the minimum needed to run it.
A randomly generated anonymous player ID (in your browser's storage), the display name you type, your chosen skin and settings, and gameplay statistics tied to that anonymous ID (best score, kills, games played, unlocks). None of this identifies you personally. No email, no account, no password.
We don't sell data, run trackers, use analytics cookies, or collect personal information. Display names appear on public leaderboards; pick any name you like.
Our game server briefly processes IP addresses to run the connection and prevent abuse (rate limiting); they are not stored with your game data. If the game crashes, an anonymous error report (error message and browser version) may be sent to help us fix it.
When played on partner platforms (e.g. CrazyGames), that platform's own privacy policy applies to its ads and accounts; game progress may sync via the platform's save system.
Clearing your browser storage resets your local identity. To request removal of a leaderboard entry, contact powell.gregory@icloud.com.
