These Terms of Service (Terms) govern your access to and use of our services, including our various websites, email notifications, applications, blogs, and other services which link to these terms. These terms also govern any information, text, links, graphics, photos or other material uploaded, or appearing on the Services offered, referred hereafter as (Content). By using the services you agree to be bound by these Terms.
Lichess.org hereafter (Lichess) can be considered a digital version of an analogue chess club. Users of the site are encouraged to use our services and content to develop their understanding of chess and to further the pursuit of chess.
Lichess is open source and run by volunteers. Occasional downtime may occur which may affect Lichess' services on offer. Lichess takes no liability for negative effects of downtime.
Lichess is designed to be open to all who are willing to agree to form a binding contract with Lichess and are able to receive services under the laws of the applicable jurisdiction. Users must be at least 13 years old to use the Services. If you accept these Terms on behalf of a company, organization government, or other legal entity, you represent and warrant that you are authorized to do so. Lichess withholds the right to request proof of identity from those claiming to hold representation from the above entities in addition to players claiming certain titles or public or notable identities.
Users, both registered and unregistered, agree to behave with good conduct whilst benefitting from Lichess' services. Certain behavior will result in action being taken against the account including banning or closing the account.
User conduct is contextual, and different penalties may apply at the administrators' discretion. What determines good conduct may change at Lichess' discretion.
Exceptionally, users can play as a team. This must be done on a specially made team account, which explicitly states the team nature of the account (for example, in the bio page). This is primarily intended for entertainment or educational purposes, and administrators retain final say as to whether an account is a legitimate team account or not. Some examples of team accounts could be: entertainment use in streamed bullet tournaments where effective consultation is impossible; custom tournaments created by the team account; in private challenges and lobby games where the opponent explicitly consents.
The administrators' discretion is final.
