HanziLens Privacy Disclosure

HanziLens analyzes Chinese text selected by the user on webpages.

Data collected or transmitted

When you select text on a webpage and choose to analyze it, HanziLens sends the selected text to the HanziLens API at https://api.hanzilens.com/parse. If you hover or click dictionary features, the selected Chinese word or phrase is sent to https://api.hanzilens.com/definitionLookup.

HanziLens does not continuously read webpages. It only sends webpage content after you explicitly invoke analysis through the context menu or keyboard shortcut, or when you request a dictionary lookup inside the HanziLens popup.

Third-party processing

The HanziLens backend may send selected text to its configured AI provider for linguistic analysis and translation. The current backend uses OpenRouter for text analysis. Dictionary lookup is handled by the HanziLens backend using its dictionary database.

Storage

The extension stores your theme preference locally in your browser. The extension does not store selected webpage text locally.

Retention

Selected text and dictionary lookup tokens are processed by the HanziLens backend to return analysis results. Server logs may include request metadata such as time, route, and IP address for security, abuse prevention, and debugging. HanziLens does not use selected webpage text for advertising or sell user data.

Permissions rationale

HanziLens requests access to website content because it needs to read the text you select on webpages when you ask the extension to analyze it. It requests access to https://api.hanzilens.com/* so the extension can communicate with the HanziLens backend.
