Anonymous play statistics

To learn whether the game is fun and whether people come back to it, the game sends anonymous events to Umami, a privacy-focused analytics service. It sends things like "a level was started" or "a level was won" along with the level number, plus your screen size and language. Each device gets a random code that's made on the device, so we can count returning players. That code isn't linked to your name, email or any account.

Umami uses no cookies and doesn't track you across other websites. We don't sell or share this data, and we only use it to improve the game.
