Privacy Policy | Last Updated: August 2026
Your privacy is of the utmost importance to us. This Privacy Policy explains how the Trees Pinyin Web Annotator browser extension handles information when you use it.
The Trees Pinyin Web Annotator does not collect, store, or transmit any personal data, browsing history, or sensitive user information. All processes are executed locally within your web browser.
When you use the extension to annotate web pages with Trees Pinyin guides, the phonetic translation is performed entirely on your local machine using our embedded, offline database (pinyin-pro.js). No data is sent to external servers or third-party services.
The extension does not integrate any third-party analytics, tracking libraries, or advertising networks. Your web-browsing activities remain completely private to you.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated modification date.
If you have any questions or suggestions about our Privacy Policy, please feel free to contact us via our official website.
