Privacy Policy

1. Personal Information We Collect

The App does not require account registration and does not directly collect personal information such as your name, email address, or phone number. We do not operate any servers, and all data entered by the user is stored only on the device.

2. Data Stored on Your Device

The following data is stored locally on your device (SharedPreferences) for the App to function properly:

• App installation date
• Saved passages and Chinese character card lists
• Notification settings (time, enabled/disabled)
• Font size preferences
• Consecutive visit records (streak)
• Onboarding completion status

This data is never transmitted to external servers and is deleted when you uninstall the App.

3. Analytics (Firebase Analytics)

The App uses Google Firebase Analytics to improve our services. Firebase Analytics may collect the following non-identifiable data:

• Screen view events (which screens are visited)
• Key in-app action events (sharing, bookmarking, character learning, etc.)
• Technical information such as device model, OS version, and app version
• Approximate location information (country/city level)

This data is collected in a non-personally identifiable form and is processed in accordance with Google's Privacy Policy. You can limit analytics data sharing through your device settings.

4. Sharing with Third Parties

Other than the non-identifiable analytics data collected through Firebase Analytics, the App does not share any personal information with third parties.

If you enable notifications, local notifications will be sent at your scheduled time. These are processed entirely on your device and do not use any external servers. Notifications can be disabled at any time in your settings.
