Privacy Policy

1. Information We Collect

This application stores your learning progress locally in your browser using localStorage. We do not collect, transmit, or store any personal information on external servers.

2. Local Storage

We use browser localStorage to save your learning progress, including:

• Completed sentences and templates
• Last visited content

This data remains on your device and is not accessible to us or any third parties.

3. Device Sync via QR Code

Our sync feature works entirely without servers. When you generate a QR code to sync progress between devices:

• Your progress data is encoded directly into the QR code image itself.
• No data is sent to the cloud or any intermediate server.
• The data transfer happens directly between your devices (via camera scanning).

4. Text-to-Speech

The app uses your browser's built-in speech synthesis API for pronunciation features. No audio data is transmitted externally.

5. Cookies and Analytics

We use Google Analytics to understand how visitors engage with our application. Google Analytics uses cookies to collect information on your usage behavior. This data is anonymized and used solely to improve the user experience.

6. Third-Party Services

We use Google Analytics as a third-party service for usage tracking. We do not share your personal learning progress with any third parties for advertising purposes.

Some images in this application are generated using AI image services. No user data is shared with these services; images are pre-generated based on sentence content.

7. Data Deletion

You can clear your learning progress at any time through the app's reset function or by clearing your browser's localStorage.

8. Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
