We use the minimum technical storage required for the app to work.
What we store
- Sign-in session. An auth token in secure storage so you don't sign in every time.
- UI preferences. Language, theme (light/dark) and background-music choice — in browser localStorage.
- Guest token. While you are not registered, a local guest-session ID is stored so your cards aren't lost.
- Referral tag. If you arrive via a friend's link, we temporarily store the referral code.
Advertising and tracking
We do not use advertising cookies and do not share data with ad networks.
How to disable
You can clear storage in your browser settings. You'll need to sign in again and UI preferences will reset to defaults.
