Best Chess Move CalculatorPrivacy policy
Short version: we do not collect personal data. The calculator runs entirely in your browser.
This site is run by the team behind ChessHelper (chesshelper.ai). This policy covers bestchessmovecalculator.com only. Last updated November 12, 2026.
The calculator
When you calculate a move, the position is analyzed by a copy of Stockfish running inside your browser tab. Positions you enter or play are never sent to us or to any server, and they are not stored after you close the page.
No accounts, cookies, ads or analytics
There are no user accounts. The site sets no cookies, runs no advertising and loads no analytics or tracking scripts. It makes no requests to third-party servers: fonts, scripts and the engine are all served from this domain.
Hosting
The site is a static website hosted on Cloudflare Pages. Like any web host, Cloudflare may process technical request data, such as IP addresses, browser type and the pages requested, to deliver the site and protect it from abuse. That processing is covered by Cloudflare's own privacy policy.
If you email us, we receive your email address and whatever you choose to write. We use it only to reply and to fix what you reported, and we do not add you to any mailing list.
Links to other sites
Pages link to other websites, including chesshelper.ai, Lichess and Chess.com. Those sites have their own privacy policies.
