Terms of Use

1. Acceptance of terms

By accessing or using QueenDash (queendash.com, "the Service"), you agree to be bound by these Terms of Use. If you do not agree, please do not use the Service. These terms apply to all visitors, registered users and any other persons who access the Service.

2. Description of the Service

QueenDash is a chess data aggregation and visualisation platform that provides:

• FIDE official rating rankings (Standard, Rapid, Blitz, Women) with historical data.
• Live tournament standings and game results sourced from Lichess broadcasts and official FIDE communications.
• Historical results from World Chess Championships, Candidates Tournaments, Chess Olympiads and World Rapid & Blitz Championships.
• Game analysis powered by Stockfish 16 (open-source chess engine).
• An interactive world map of FIDE-registered players by country.
• Player profiles for selected elite players.
• Optional personal accounts for saving preferences and linking platform usernames.

The core Service is provided free of charge and does not require registration. Optional premium features may be introduced in the future; they will always be clearly marked and voluntary.

3. User accounts

If you create an account, you are responsible for maintaining the confidentiality of your credentials and for all activity under your account. You agree to:

• Provide accurate information during registration.
• Not create accounts using automated means or under false identities.

• Notify us immediately at [email protected] if you suspect unauthorised access.

We reserve the right to suspend or terminate accounts that violate these terms.

4. Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of applicable regulations.
• Scrape, crawl or systematically download data from QueenDash APIs or web pages at a rate that imposes unreasonable load on our infrastructure. Fair personal use (a few hundred requests per day) is welcome; automated mass extraction is not.

5.2 Third-party data

Rating data is sourced from FIDE (Fédération Internationale des Échecs) official publications. Game scores are sourced from Lichess broadcasts and other public chess databases. These are subject to their respective terms. Stockfish is used under the GNU GPL v3 licence.

5.3 Your content

You retain ownership of any content you submit (e.g. linked usernames). By submitting it, you grant QueenDash a limited licence to use it solely to provide the Service to you.

6. Disclaimer of warranties

To the maximum extent permitted by applicable law, QueenDash and its operators shall not be liable for any indirect, incidental, special, consequential or punitive damages, including loss of data, profits or goodwill, arising from your use of (or inability to use) the Service.

Our total liability to you for any claim arising from these terms or the Service shall not exceed €50 (or the amount you paid us in the 12 months preceding the claim, if greater).

8. Availability and changes

We may modify, suspend or discontinue any part of the Service at any time without notice. We may also update these terms; the updated date at the top will reflect any changes. Continued use after an update constitutes acceptance of the revised terms.
