On your device: your progress, settings and purchases are stored in this app or browser only.

On our server: when you play Cascade or the rankings, we store your display name, country flag, scores, the level you reached and a random player ID. We don't collect your real name, email address or location.

Ads: the web version only simulates ads (no ad network, no tracking). The Android app uses Google AdMob for real ads and asks for your choice where the law requires it. On iPhone it also asks before using the advertising ID (you can say no and still play everything).

Fonts and game files come from our own server, not from Google or other font services.

Delete your data: clear this site's data or uninstall the app. To remove your ranking entries, contact the developer.

Names: display names in the rankings are filtered. Tap the flag next to a name to report it; reported players are hidden for you.
