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.
