This app works without an account. Your learning progress (favorites, strengths, settings) is stored locally on your device.

1) Data we store
• Local progress and settings (on-device storage).
• Optional backup files you export/import (you control where they are stored and shared).

2) Ads and purchases
• The app may show ads via Google AdMob. Depending on your choice, ads can be personalized or non-personalized.
• AdMob may collect device identifiers, IP address and usage data to serve and measure ads.
• Purchases/subscriptions are processed by Apple/Google. We do not receive your payment card details.

3) Data deletion
• Use “Reset progress” in Settings to remove local learning data.
• Uninstalling the app removes local data. Backups you exported remain in locations you chose.
