Terms of use

Last updated: November 13, 2026. These terms cover your use of ChessCheatScan. Contact: support@chesscheatscan.com.

What the service is

ChessCheatScan compares the moves in a chess game with a chess engine and reports statistics and a suspicion score. A score is a statistical anomaly, not proof of cheating. Honest players can score high, and players who had help can score low.

Using it fairly

Do not use a scan to publicly accuse, harass or defame anyone. If you think someone cheated, report the game to the site where it was played. Do not try to get around the scan limits, overload the service, or resell it.

Accounts and subscriptions

Guests and free accounts receive two free scans per rolling seven-day period, subject to network limits. An account is not required for guest scans. Pro is a recurring subscription billed through Stripe until you cancel. You can cancel at any time from your account; Pro stays active until the end of the period you paid for. Pro has a daily fair-use cap.

No warranty

The service is provided as is. We do not promise that results are accurate or that the service will always be available. To the extent the law allows, we are not liable for losses that follow from relying on a scan.

Changes

We may change these terms or the service. If a change matters, we will say so on this page.

ChessCheatScan is not affiliated with Chess.com or Lichess.
