Privacy Policy for FenScanner & Analyzer

Last updated: October 25, 2026

This Privacy Policy applies solely to the browser extension FenScanner & Analyzer on chesssearch.com ("the Extension"), provided by chesssearch.com.

1. No Data Collection

The Extension is designed to operate 100% locally on your device. We do not collect, store, transmit, or process any personal data, usage metrics, web activity, browsing history, or sensitive user information.

2. Image & Content Processing

When you scan a chessboard diagram or take a screenshot using the Extension, all image analysis, FEN conversion, and Stockfish evaluations occur entirely inside your browser runtime. No images, screenshots, or extracted chess positions are uploaded to external servers or third-party services.

3. Permissions Usage

The Extension requests minimal browser permissions strictly needed for its single core function:

  • activeTab: Temporarily grants access to the active tab only when you click the extension icon to capture board diagrams.
  • scripting: Allows execution of the local board scanning script on the active page.

4. Third-Party Sharing & Sales

Since we do not collect any user data, we do not sell, license, transfer, or share any information with third parties, advertisers, or data brokers under any circumstances.
