Who we are
Cipher Siege (“we”, “us”) is a free browser game available at https://cipher-siege.vercel.app. This policy explains what information we collect and how it’s used.
Information we collect
- Account data: if you create an account, your email address and chosen username. Guest players receive an anonymous account identifier.
- Game data: your progress, gold, levels, match results, friends and clan membership.
- Device storage: we store sign-in session tokens and settings (such as sound volume) in your browser’s local storage.
- Technical data: standard server logs (such as IP address and browser type) kept by our hosting providers for security and reliability.
How we use it
To run the game, save your progress, show leaderboards and social features, prevent cheating and abuse, and keep the service secure. We do not sell your personal information.
Service providers
We use Supabase for accounts and game data and Vercel for hosting. They process data on our behalf under their own security and privacy commitments.
