Privacy Policy

Last updated: February 1, 2026

Yuci ("we") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and protect your information.

Data Collection

Yuci operates on a "local-first" principle: Translation results are cached locally using Chrome Storage API. We do not collect, store, or transmit your personal data to any server.

Permissions

  • storage Cache translation results locally
  • activeTab Read current page content for translation
  • offscreen Background translation processing
  • host_permissions Access webpage content to provide translation service

Third-Party Services

If you configure external translation APIs (such as OpenAI, DeepL), your translation requests are sent to those services. Please review their respective privacy policies. When using Chrome AI or Ollama, all processing is done locally.

Data Retention

Translation cache is automatically cleared after 7 days. You can manually clear all data at any time in the extension settings.

User Rights

You can at any time: View cached translation count, export word book data, clear all local data, uninstall the extension to delete all data.
