Why Privacy Matters in Chess Analysis

When analyzing your chess games, you may be revealing your playing style, strategic preferences, and areas where you're working to improve. We believe this information should remain private. That's why we've designed our tool to process everything locally in your browser, ensuring your games and analysis never leave your device.

Local Processing Benefits

Complete Privacy: Your games are never transmitted to our servers or any third party
Faster Analysis: No network latency - analysis happens at the speed of your device
Offline Capability: Once loaded, the tool can work without an internet connection
No Data Retention: We can't lose or leak data we never collect

How We Protect Your Data

Beyond local processing, we implement multiple layers of security and privacy protection:

Technical Measures

HTTPS Encryption: All connections to our website use industry-standard TLS encryption
WebAssembly Sandboxing: The Stockfish engine runs in a secure, isolated environment
No Server-Side Storage: We don't maintain databases of user games or analysis results
Minimal Data Collection: We only collect anonymous analytics to improve the service

Third-Party Integrations

When you fetch games from Chess.com or Lichess, we make direct API calls from your browser to their servers. We act as a pass-through and don't store or log these requests. Your authentication with these platforms remains between you and them.
