Privacy Policy

Last updated: July 2026

Our Commitment

At Chess Online, we take your privacy seriously. This policy explains what data we collect — which is essentially nothing.

No Data Collection

Chess Online is a purely client-side application. The game runs entirely in your browser. We do not:

• Collect personal information
• Use cookies for tracking
• Run analytics or tracking scripts
• Sell or share any data with third parties
• Require user accounts or registration

Local Storage

Chess Online uses your browser's localStorage to save your preferences locally on your device. This includes:

• Theme preference (light or dark mode)
• Difficulty level selection
• Cookie consent acknowledgment

This data never leaves your device. It is not transmitted to any server. You can clear this data at any time by clearing your browser's local storage.

No Server-Side Processing

All chess game logic — move generation, AI computation, validation — executes entirely within your browser. No moves or game data are sent to any server.

Third-Party Services

This website loads the Google Fonts stylesheet for the Crimson Text font used in headings. Google may collect usage data according to their privacy policy when fonts are loaded. No other third-party services are used.
