Supported Languages
Languages available in the app
You can change the app language in Settings. You can also follow the system language.
Data Storage & Security
On-device + optional cloud
The app keeps data locally with SwiftData and UserDefaults. When you sign in, learning progress can sync via Firebase across your devices.
Guest mode
Guest mode avoids collecting personal identifiers like email, but progress isn’t synced to the cloud. Some features (ads, backup, sign-in) need a network connection.
Transparency
Usage analytics, ads on the free tier, and third-party services (e.g. Firebase, AdMob) are described in detail in our Privacy Policy.
