Privacy Policy
ChessTension.com is built as a fast, privacy-first chess board control and square tension analysis tool. All board calculations run locally in your browser.
1. Client-Side Chess Position Processing
When you move pieces, draw tactical arrows, load an opening preset, or paste a custom Forsyth-Edwards Notation (FEN) string on ChessTension.com, all square control and battery calculations are computed directly in your web browser. We do not transmit or store your analyzed FEN positions on external database servers.
2. Personal Data & Direct Correspondence
ChessTension.com does not require user registration, accounts, or login credentials. If you choose to contact us via email at contact@chesstension.com, we use your email address and message content solely to respond to your inquiry or review your opening preset suggestion.
3. Cookies & Browser Storage
We do not use third-party advertising trackers or cross-site profiling cookies. Standard transient browser state is used strictly to render the interactive chessboard, visual layer filters, and URL query parameters (?preset= and ?fen=).
