Terms of Service

• You accept these Terms by ticking the box when you create an account (or, for existing accounts, when the app asks you to). Our Privacy Policy and Cookie Policy explain how we handle your data; they are information for you, not a contract you have to accept. If you do not agree with these Terms, please do not use the Service.
• We record on your account which version of these Terms you accepted, when, and in which language.

ChessNotes is provided free of charge by Francesco Albano, a private individual in Italy, not acting for business purposes. Contact: albanofrancesco22@libero.it.

You must be at least 14 years old (the age of digital consent in Italy) to create an account. If you are under 18, you confirm that a parent or legal guardian has agreed to your use of the Service.

ChessNotes is a web tool to build and memorise chess opening repertoires. Its main features are:

• You are responsible for the accuracy of the information you provide and for keeping your login credentials confidential.
• You must not share your account credentials or allow others to use your account.
• Tell us promptly at albanofrancesco22@libero.it if you believe your account has been compromised.
• We may suspend or close accounts that seriously or repeatedly breach these Terms or the law, as described in section 14.

You agree not to:

• Some features use services provided by third parties: chess.com (Published-Data API), Lichess (game export, studies, cloud evaluation, opening explorer) and Stockfish (an open-source engine distributed under the GPLv3 licence). ChessNotes is an independent project and is not affiliated with, endorsed by or sponsored by chess.com or Lichess. Their names are used only to describe the integrations.
• Your use of those platforms remains governed by their own terms and privacy policies. Their availability, limits and data are outside our control: if a platform changes or stops its API, some features may stop working.
• You may connect only chess.com or Lichess usernames that belong to you or that you are authorised to analyse. Imported games contain other players’ public usernames and ratings: use them only for your own chess study.
• You can disconnect a username at any time; its imported games are then deleted (see the Privacy Policy).
• The open-source software, fonts and other material we use, with their licences, are listed on the Licences & credits page.

• You keep full ownership of the repertoires, positions, notes and other content you create in ChessNotes (your “User Content”).
• You grant us a non-exclusive, royalty-free licence to host, store, copy and display your User Content solely to provide the Service to you. This licence ends when you delete your content or your account.
• You are responsible for your User Content and confirm that you have the right to store it (including when you import studies, PGN files or courses).
• We do not claim ownership of your content and will never use it to train machine-learning models or for advertising.

• The Service’s design, text, logo and our own source code belong to Francesco Albano or its licensors, except for open-source components that remain subject to their own licences (for example Stockfish, GPLv3).
• We grant you a limited, non-exclusive, non-transferable licence to use the Service for personal, non-commercial purposes under these Terms. It is revocable only in the cases described in section 14.
• “Stockfish”, “Chess.com” and “Lichess” are names or trademarks of their respective owners.

• Engine evaluations, opening statistics, suggested moves, coverage scores and the analysis of your games are informational. They are produced automatically (also by third-party services) and may be incomplete or wrong, for example because of limited engine depth or missing data. They are not coaching advice and do not guarantee any improvement of your results or rating.
• We work to keep the Service available and your data safe, but as a free service run by an individual we cannot guarantee that it will be uninterrupted or free of errors. Keep a PGN export of repertoires that are important to you.
• If something does not work as described, tell us at albanofrancesco22@libero.it and we will try to fix it.

• We are not liable for damage caused by events outside our reasonable control, such as outages or changes of third-party services (including chess.com and Lichess) or of your internet connection.
• Nothing in these Terms excludes or limits our liability for wilful misconduct or gross negligence (Art. 1229 of the Italian Civil Code), for death or personal injury, or any other liability that cannot be excluded or limited by law.

If you use the Service in breach of these Terms or of the law (for example by uploading content that infringes someone else’s copyright), you are responsible for the resulting claims of third parties, within the limits set by applicable law.

• We may update these Terms, for example to describe new or changed features, to follow changes of the law or of third-party services we rely on, to improve security, or to make the text clearer. We announce material changes with an in-app notice (and by email where reasonably possible) at least 14 days before they take effect for existing users, and we may ask you to accept the new version in the app. For new accounts the current version applies from sign-up.
• If you do not agree with a change, you can close your account before it takes effect.
• This is version 3.0.0, published on 2026-10-01 and effective for existing users from 2026-10-15, or from when you accept it in the app, if earlier.

• You can stop using the Service and close your account at any time, at no cost. To close your account and have your data deleted, use Delete account in the app (account menu → Profile & progress → Privacy) or email albanofrancesco22@libero.it from the address linked to it.
• We may suspend or close an account, or remove content, only in case of serious or repeated breach of these Terms or of the law, or where required by law. Except in urgent cases (for example security or abuse) we will warn you first in the app (and by email where reasonably possible) and, where possible, let you export your repertoires.
• If we decide to discontinue the Service, we will try to give at least 30 days’ notice in the app, unless prevented by reasons beyond our control, so you can export your data.
• On closure your data is deleted as described in the Privacy Policy. Sections 8, 10, 11, 12 and 15 continue to apply as needed.

• Italian law applies. If you are a consumer, you keep the protection of the mandatory rules of your country of residence.
• If you have a problem, please write to us first at albanofrancesco22@libero.it: most problems can be solved quickly.

• For any question about these Terms: albanofrancesco22@libero.it.
• Accessibility: we try to make ChessNotes usable with keyboard and screen readers. If something is hard to use because of a disability, write to albanofrancesco22@libero.it and we will try to help or fix it.
