Terms of service
Last updated: 13 November 2026
These terms apply when you use chesscomfort.com ("Chess Comfort", "we"). Chess Comfort is run by an individual based in Ireland. Contact: hello@chesscomfort.com. By using the site you agree to these terms.
The service
Chess Comfort helps you learn chess: build and practise opening trees, analyse positions with a chess engine and solve puzzles. Most of it is free. Some features are part of a paid subscription, Chess Comfort Premium.
Your account
You can use the site without an account. If you sign in with Google, you are responsible for your Google account. Accounts are for people aged 16 or over. You can delete your account at any time in Settings.
Premium subscriptions and payment
- Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Paddle's buyer terms also apply to your purchase.
- Premium is billed monthly or yearly, in advance, until you cancel. The price and the date of each charge are shown before you pay and on the Premium page.
- Free trial: new subscribers get a 7-day free trial. You need to enter a payment method. If you don't cancel before the trial ends, the first payment is taken when the trial ends. One free trial per person.
- Cancelling: you can cancel in one click on the Premium page at any time. You keep Premium until the end of the period you already paid for, and you will not be charged again.
- Refunds are explained in our refund policy.
- If we change the price, we will tell you before it applies to you, and you can cancel before then.
Acceptable use
Don't attack, overload or try to break the site, don't access other people's data, and don't use automated tools to copy the site's content in bulk. We may suspend accounts that do.
Content and licences
Your opening trees are yours. The site uses open-source software and open data (for example Stockfish, chess.js, cm-chessboard and the Lichess puzzle and opening databases); their licences are credited on the site.
No guarantees
We work hard to keep Chess Comfort available and correct, but the service is provided "as is". Engine evaluations and lessons may contain mistakes. To the extent the law allows, we are not liable for indirect losses. Nothing in these terms limits your rights as a consumer under the law of the country where you live.
Changes and ending
We may update these terms; the date at the top will change, and for important changes to paid plans we will tell subscribers in advance. If we ever close Premium, we will refund the unused part of any prepaid period.
Law
These terms are governed by the laws of Ireland. You can also rely on the mandatory consumer protection rules of the country where you live.
