Privacy Policy

Last Updated: June 19, 2026

Your privacy is critically important to us. This Privacy Policy governs the use of the mobile and desktop applications named 啱音字 (canTone) (the "Application").

1. Zero Personal Data Collection

The Application is built using an offline-first, local-only architecture.

  • We do not collect, transmit, store, or share any personal information, search queries, lyrics text, or user preferences.
  • We do not use cookies, analytical software, or third-party tracking SDKs.

2. Local Database Security

All application data, search cache registries, and custom secure database keys are stored strictly locally on your physical device. No remote servers ever have access to your data.

3. Third-Party Links

Our application may link to external, public pages (such as GitHub release pages). We are not responsible for the privacy practices or contents of those external sites.

4. Children’s Privacy

Because we do not collect any user data whatsoever, the Application is fully compliant with the Children's Online Privacy Protection Act (COPPA).
