Terms and conditions of use
If there is any discrepancy between language versions, the Spanish text prevails.
1. Holder and acceptance
These Terms govern the use of Nexa chess (https://nexachess.com), a service provided by REBOL TECHNOLOGIES S.L. (Unipersonal), NIF B23982747, registered office C/ Colón 20, Esc. C, 4º C, 03570 La Vila Joiosa (Alicante), España. By using the service or registering, you accept these Terms, the Privacy Policy and the Cookie Policy.
2. Description of the service
Nexa chess is a free web and Android chess-game analysis application that imports, at the user’s request, their public Lichess and Chess.com games and analyses them with the Stockfish engine.
3. Third-party services and no affiliation
The service imports, at your request, your public games through the public Lichess and Chess.com APIs. Operation depends on the availability and terms of those platforms, which may limit or withdraw access at any time. We therefore do not guarantee that import is always available. When you use those platforms you remain subject to their own terms. Nexa chess is not affiliated with or endorsed by Chess.com or Lichess.
4. Fair play
It is forbidden to use Nexa chess to receive help during ongoing games. The service only analyses finished games.
5. Age
You must be 14 or older or have the consent of your parents or guardians.
6. Acceptable use
The following is not permitted:
- (a) using the service unlawfully or contrary to third-party rights or the terms of the source platforms;
- (b) linking other people’s usernames to analyse or profile them without their knowledge;
- (c) accessing other users’ data, breaching security or overloading the infrastructure;
- (d) extracting, reselling or redistributing the service’s data or results at scale or by automation;
- (e) reverse engineering, except as permitted by law.
7. Intellectual property
The application, design, algorithms, metrics and analysis texts belong to the holder. We grant you a personal, non-exclusive, non-transferable licence to use the analysis of your games, and you may share it for non-commercial purposes citing Nexa chess. Chess moves are not subject to copyright. Stockfish is distributed under the GPLv3 licence.
8. Advertising
The free version is funded with Google AdSense ads, shown according to your cookie preferences.
Suspension
We may suspend or cancel access for anyone who breaches these Terms. Where possible we will give prior notice and the reason, and you may reply at contact@nexachess.com.
Liability
The service is provided with due care, but without a guarantee of uninterrupted availability or absolute accuracy of results. We are not liable for indirect damages or interruptions caused by third parties. Nothing above excludes or limits liability for wilful misconduct or gross negligence, or the rights that consumer law (TRLGDCU) grants to consumers.
Changes
If we make substantial changes, we will give you advance notice. If you disagree, you may stop using the service and, where applicable, cancel.
Governing law and jurisdiction
Spanish law applies. If you are a consumer, the courts of your place of residence have jurisdiction. Contact: contact@nexachess.com.
