Privacy Policy

Account data: your email address and a password (stored as a secure hash by our authentication provider — we never see the password itself).

Game data:the Clash Royale player tag you claim, and the battle history for that tag as returned by the official Clash Royale API (opponents, decks, results, trophies). Battle logs are public data exposed by the game's API; we archive them so they aren't lost when the game discards them.

Usage data: timestamps of when you last signed in, used to run our inactivity policy. We do not run third-party advertising or tracking scripts.

To operate the service: fetching and archiving your battles, showing you your history and analytics, and computing anonymous, aggregated community statistics (deck and card win rates by trophy range) that cannot be traced back to you.

Battle history is kept for a rolling 6 months; older battles are deleted automatically. If you don't sign in for 30 days we pause tracking; after about 5 months of inactivity we email you a warning, and at 6 months your account and all its data are permanently deleted. Anonymous community aggregates are kept for up to 12 months.

From Settings you can export everything we hold about you as JSON, or delete your account and all associated data immediately and permanently.

Data is stored with Supabase (Postgres database and authentication, hosted in the United States) and the site is served by Vercel. These providers process data on our behalf; we don't sell or share your data with anyone else.
