All built on one principle: your data stays yours.
Every app under the Misket umbrella runs on device. None of them has an account system, a server or analytics. The amount of data they collect is zero.
Some apps use Apple's own services: StoreKit for purchases, Game Center for leaderboards, WeatherKit for weather data and Screen Time for app blocking. Data handled by those services falls under Apple's privacy policy and is never passed to us.
