Preview usage terms
About this preview
ChessSum combines imported public chess history and provides analysis, learning and community features. This is a preview; features, import coverage and access allowances can change.
Accounts and source platforms
Only claim ownership of accounts that are yours. Following a public username does not verify ownership or make that player a ChessSum member. Follow the source platform's rules when using its accounts.
Responsible use
Do not harass other members, publish private information without permission, impersonate people or submit misleading community listings. Administrators can review reports and restrict abusive use.
Accuracy and limitations
Imported history may be incomplete. Ratings remain specific to their source and time control. Analysis and AI explanations may be wrong; verify suggestions on the board. Community approval does not guarantee an organizer's services.
Before public launch
Final service terms, operator contact and any paid-plan conditions will be published before public registration and payments open. These preview terms do not announce a paid subscription.
