Best Chess Analysis App
Terms of use
Plain-language terms for using this site. Updated November 12, 2026.
By using this site you agree to these terms. The site is published by the team behind ChessHelper (chesshelper.ai), which is our own product.
Information only
Everything here is general information about chess analysis tools and chess improvement. It is not professional advice. Features and prices of the products we describe change; we state the date we checked them, and the vendor's own website is the final word.
No warranty
We work to keep the site accurate, but we provide it "as is", without any warranty of accuracy, completeness or fitness for a particular purpose. To the extent the law allows, we are not liable for losses arising from your use of the site or of products it describes.
Fair play
You agree to use what you learn here fairly. Chess.com, Lichess, FIDE and US Chess forbid outside help during games, and Chess.com's fair-play policy covers unrated games against people too. Use analysis tools on finished games, for study, and for practice against bots or in analysis mode. Using an engine in a game against another person is cheating and is not allowed.
Content and trademarks
The text and page design are ours. Photos and chess piece images belong to their authors and are used under the licenses listed on our credits page. Product names such as Lichess, Chess.com, ChessBase, Fritz, DecodeChess and En Croissant belong to their owners and are used only to identify those products; their mention does not imply endorsement of this site.
Links
We link to other websites for reference. We are not responsible for their content or practices.
Changes and contact
We may update these terms; the date above shows the latest version. Questions go to contact@bestchessanalysisapp.com.
