Terms of Service
1. The service
ChessKhan is an online chess platform: games against people and computer opponents, puzzles, and chess courses with a spoken coach. By creating an account or using the site you agree to these terms. If you do not agree, please do not use the service.
2. Accounts
- You must be at least 13 years old. If you are under 18, a parent or guardian must agree to these terms for you.
- One account per person. Keep your password private; you are responsible for what happens under your account.
- Give a real email address so we can reach you about your account and payments.
3. Fair play
Rated games must be played by you, without help from chess engines, other people or outside tools. We analyse games for signs of engine use; accounts found cheating lose their rating and may be closed. Be respectful to other players: abuse, harassment and hate speech are not allowed.
4. Premium subscription and free trial
- Parts of the service (full courses, unlimited puzzles) require a Premium subscription, billed monthly or yearly.
- New accounts may get a free trial. A payment method is required to start it, and the subscription is charged automatically when the trial ends unless you cancel before then. We show the trial length and the price before you start.
- Subscriptions renew automatically until cancelled. You can cancel at any time from your Account page; you keep access until the end of the period you paid for.
- Payments are processed by Stripe, PayPal or QPay. We never see or store your full card number.
- Prices are shown in US dollars or Mongolian tögrög and may include taxes where the law requires.
5. Refunds
Because the content is available immediately, subscription payments are generally not refunded, except where the law gives you a right to a refund or where something on our side went wrong (for example, you paid but did not get access). Write to [email protected] within 14 days and we will look at it.
6. Content and intellectual property
The courses, coach commentary, voice recordings, designs and software of ChessKhan belong to us or our licensors. You may use them for your own learning. You may not copy, resell, scrape or redistribute them. Games you play are yours to share; by playing on the site you let us show them publicly and use them to improve the coach and the fair-play system.
7. Changes and termination
We may change or stop features, and may update these terms; we will tell you about important changes by email or on the site. You may delete your account at any time. We may suspend or close accounts that break these terms.
8. Liability
The service is provided "as is". To the extent the law allows, we are not liable for indirect losses, and our total liability is limited to what you paid us in the last 12 months. Nothing here limits rights that the law does not let us limit.
