Welcome to Chess (the “Site”). The Site is an online chess site operated by chessmanor.com (“we”, “us”). By browsing the Site or playing chess on it, you confirm that you have read, understood and agree to these Terms. If you do not agree with any part of them, please do not use the Site.

How we handle data about you is described in our Privacy Policy, which forms part of these Terms.

01The service

The Site offers free browser chess: you play against the computer in your browser, with nothing to install and no sign-up.
The Site also offers guides on the rules of chess, how the pieces move, move notation, openings, tactics, checkmates and endgames.
The Site currently has no paid content and does not sell any virtual items.

02For entertainment only — no real money

Wins, losses and records in the game are just game records. They have no real-world value and cannot be exchanged for cash, goods or services.
You may not use the Site for gambling or for any activity where real money or goods are won or lost, and you may not use results from the Site as the basis for such activity.
You are responsible for following the laws where you live.

03Your game data lives on your device

The Site has no accounts. Game settings, lobby choices and similar data are stored only in the browser you are using.
If you clear your browsing data, use a private window, or switch devices or browsers, that data will be gone. We keep no copy and cannot restore it for you.

04Guides and the computer opponent

Rules explanations follow the rules used by the game on this Site. For example, threefold repetition and the 50-move rule end the game in a draw here automatically, while in over-the-board tournaments a player usually has to claim the draw. Tournaments and clubs may have different rules; where they differ, follow the rules of that occasion.
The computer opponent's moves and difficulty reflect only the judgement of the programs the Site uses. They are for practice and reference only and are not guaranteed to be the best moves. What the computer says in the game chat is generated automatically and does not represent our views.

05Intellectual property

Unless stated otherwise, the code, design, illustrations, text and board diagrams on the Site are our copyright.
Third-party material is used under its own licence: the piece images are the cburnett set by Colin M.L. Burnett (BSD 3-Clause licence), and the computer opponents use Maia (AGPL-3.0) and Stockfish (GPL-3.0), whose licence texts and source locations are provided on the Site under /maia/ and /stockfish/. That material is governed by its licence terms and is not subject to the next point.
You are welcome to share links to pages on the Site. You may not copy, republish or reproduce the Site's content, or use it commercially, without our written permission.

06Acceptable use

Do not interfere with or disrupt the Site in any way, including attacking our servers, spreading malware or trying to bypass security measures.
Do not use automated tools to scrape the Site in bulk or put excessive load on our servers. Normal indexing by search engines is fine.
Do not use the Site for anything unlawful.

07Links to other sites

The Site may contain links to third-party websites. We do not control third-party sites' content or data practices; please read their own terms and policies.

08Changes to the service

We may add, change or remove game content and features at any time.
We may suspend the service for maintenance, faults or reasons beyond our control, and we may shut it down permanently.

09Disclaimer and limitation of liability

The Site is provided free of charge and “as is”. We do not guarantee that it will be uninterrupted or error-free, or that its content is entirely accurate.
To the fullest extent permitted by law, we are not liable for any direct or indirect loss arising from your use of, or inability to use, the Site. Where the law nevertheless makes us liable, our total liability is limited to USD 10.

10Changes to these Terms

We may update these Terms at any time. The updated version will be posted on this page with a new “last updated” date. If you keep using the Site after a change, you accept the updated Terms.

11Governing law and jurisdiction

These Terms are governed by the laws of Taiwan, and the parties agree that the Taiwan Tainan District Court has jurisdiction in the first instance. If you are a consumer, any mandatory rights you have under the laws of the place where you live are not affected.
