Last updated: August 11, 2026
Chess.com Move Helper ("the Extension") respects user privacy and is dedicated to maintaining high standards of data protection. This Privacy Policy details our data practices regarding the extension.
1. DATA COLLECTION & USAGE
Chess.com Move Helper DOES NOT collect, store, transmit, or share any personal data, account credentials, IP addresses, or browsing history. All position evaluations and Stockfish engine calculations are executed entirely locally inside your browser session.
2. LOCAL STORAGE
The extension uses browser storage (chrome.storage.sync) strictly to persist local user settings, including:
- Selected engine depth level
- Feature toggle states (e.g. Auto-analyze, Auto-move)
- Minimum/Maximum response delay preferences
This data remains stored locally within your Chrome profile and is never sent to external servers or third parties.
3. PERMISSIONS RATIONALE
To deliver core functionality, Chess.com Move Helper requests the following browser permissions:
- Storage: Saves user preference options locally so settings persist across browser restarts.
- Host Permission (https://www.chess.com/*): Allows the extension's content scripts to read board FEN position states on Chess.com pages and render move overlays directly on the page UI.
4. THIRD-PARTY SERVICES & ANALYTICS
The extension contains no remote code execution, third-party analytics scripts, tracking pixels, or advertising frameworks.
5. CONTACT & SUPPORT
If you have any questions or inquiries regarding this Privacy Policy, please contact the developer via the official extension support channel.
