We are Chess Advisor (“Company,” “we,” “us,” or “our”).

We operate the website https://app.chessadvisor.in (the “Site”), as well as any other related products and services that refer or link to these legal terms (collectively, the “Services”).

Chess Advisor provides an automated chess analysis, game tracking, blunder recovery, and coaching analytics platform. We sync with public chess platforms (Chess.com and Lichess), analyze moves via deep engine evaluation (Stockfish), curate personalized training puzzles from players' real blunders, and provide interactive dashboards for individual players, coaches, and chess academies.

You can contact us by email at rajdeep@chessadvisor.in or through our contact page.

These Legal Terms constitute a legally binding agreement made between you, whether personally or on behalf of an entity (“you”), and Chess Advisor, concerning your access to and use of the Services.
