Terms of use

1. About these terms

These terms are an agreement between you and GreyChess (“GreyChess”, “we”, “us”) about your use of the GreyChess website, apps, browser extensions and related services (the “Service”). By creating an account or using the Service, you agree to these terms, to our privacy policy and to our cancellations and refunds policy. If you do not agree, do not use the Service.

2. Who can use GreyChess

You must be 18 or over to make an account. Someone under 18 may use the Service only with the consent of a parent or legal guardian, who accepts these terms for them and is responsible for their use, or through an academy or coach that has that consent. By using the Service you confirm that this applies to you.

3. Your account

• Give accurate information and keep it up to date. An account is for one person and may not be shared, sold or transferred.
• Keep your sign-in details, and the email or other accounts you sign in with, secure. You are responsible for everything done with your account. Tell us at once if you think someone else has used it.
• We may refuse a username, change one that breaks these terms, or ask you to confirm who you are.

4. Plans and payments

• Some of the Service is free, within limits. Paid plans, and what they include, are described on the pricing page at the time you buy. You pay the price shown at checkout.
• Your library holds up to 10 books at once on the Free plan and up to 200 on Pro, each book up to 100 MB. You may upload any number of books over time: removing a book from your library frees its place. Like the rest of each plan, these numbers may change.
• A plan paid once covers the period you chose and then ends. It does not renew by itself.
• If you choose automatic payments, your plan renews at the end of each period, and you authorise us and our payment partner to charge the payment method you approved, until you cancel. You can cancel at any time from the pricing page, in your UPI app or with your bank. Cancelling stops future charges; you keep the time already paid for.
• Payments are processed by our payment partners under their own terms. If a payment fails, we may try again, and may limit or end your paid plan until it succeeds.
• An offline payment counts only once we have confirmed it.
• We may change prices and what each plan includes. A new price applies from your next payment, and we will tell you before an automatic payment at a new price is taken.
• Promotions, discount codes, invite rewards and free time have no cash value. We may change, limit or withdraw them at any time, and cancel any benefit obtained by misuse.
• An academy’s plan follows the arrangement it makes with us. Fees an academy charges its own students are a matter between the academy and them; GreyChess is not a party to them.
• Refunds are covered by our cancellations and refunds policy.

5. Changes to the Service

The Service changes over time. We may add, change, limit, suspend or remove any part of it, including features, content and limits, at any time and without notice. A paid plan gives access to the Service as it is while the plan lasts, not to any particular feature. If we close the Service entirely, we refund the paid time you have not used.

6. Acceptable use

You agree not to:

• break any law, or use the Service for anything unlawful, fraudulent or harmful;
• upload, share or display anything that belongs to someone else without the right to; that is obscene, defamatory, harassing, hateful, misleading or harmful to children; that impersonates anyone; that contains malicious code; or that threatens the unity, integrity, security or sovereignty of India or public order;
• use the Service for help during a game you are playing, rated or casual, online or over the board;
• copy, modify, sell, rent or redistribute the Service or its content, or decompile, reverse-engineer or extract any part of it, except where the law or a part’s own licence allows it;
• access the Service by any automated means, such as bots or scrapers, or use it, its content or its output to build, train or improve any other product or service;
• interfere with the Service, put an unreasonable load on it, or get around its limits or its security;
• make more than one account, or share an account, to get around a plan, a limit or a suspension;
• harass or harm other users, or collect their information.

7. Your content

Content you add to the Service, such as files, games, notes and messages, stays yours. You are responsible for it, and you confirm that you have the right to use it.

You give us a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, adapt, display and transmit your content, and to let our service providers do so, as needed to provide, protect and improve the Service, including through features that share information with other users as the Service or your settings describe. This licence lasts while your content is on the Service, and afterwards for as long as copies remain in backups or in what has already been shared.

We do not have to check content, but we may remove or block any content, or act on any account, that we believe breaks these terms or the law. If you send us ideas or feedback, we may use them freely, with no duty to you.

8. Our property

The Service, including its software, design, lessons, studies, pictures, sounds, names and logos, belongs to GreyChess or its licensors. We give you a limited, personal, non-exclusive, non-transferable and revocable licence to use the Service as these terms allow; an academy may also use it to teach its students. All other rights are reserved. Parts made by others are used under their own licences, listed on Copyright and licences, which apply to those parts.

9. Other services

The Service may link to or work with services run by others, such as sign-in providers, chess websites, payment partners and AI providers. We do not control them and are not responsible for them, and their own terms and policies apply when you use them.

10. Analysis and learning content

Engine analysis, board readings, explanations, lessons and anything produced by automated tools are for learning only. They may be wrong or incomplete. Check them before you rely on them. We do not promise any result, such as a better rating.

11. Suspension and closing an account

You may stop using the Service and delete your account at any time from your account page. Deleting it stops its automatic payments.

We may suspend, limit or close your account, or your access to any part of the Service, at any time, if we believe you have broken these terms or the law, to protect the Service, other users or us, or where the law requires it. Paid time is not refunded when an account is closed for breaking these terms. If we close your account without such a reason, we refund the paid time you have not used. Parts of these terms that by their nature should continue after an account ends, such as sections 7 to 15, continue.

12. No warranty

The Service is provided “as is” and “as available”. To the fullest extent the law allows, we make no promises of any kind, express or implied, including that the Service will be accurate, uninterrupted, secure, free of errors, or fit for a particular purpose, or that content will not be lost. Keep your own copies of anything that matters to you.

13. Limit of liability

To the fullest extent the law allows, GreyChess, its owners, staff and partners are not liable for any indirect, incidental, special or consequential loss, or for any loss of data, profits, revenue, goodwill or opportunity, arising from the Service or these terms. Our total liability for all claims about the Service or these terms is limited to the greater of the amount you paid us in the 12 months before the claim arose and ₹1,000.

Nothing in these terms limits a liability, or takes away a right you have as a consumer, that the law does not allow to be limited.

14. Indemnity

You agree to compensate GreyChess, its owners and staff for any claim, loss or cost, including reasonable legal fees, that comes from your content, your breaking these terms, or your breaking the law or someone else’s rights.

15. Disputes

If you have a complaint, contact us first: who to write to is on Contact and complaints. Most problems can be settled that way, and we ask you to give us 30 days to try before going further.

These terms are governed by the laws of India. Subject to your rights under consumer protection law, any dispute is heard only by the courts of the city GreyChess is run from.

16. Changes to these terms

We may change these terms, the features of the Service and our prices as needed (see sections 4 and 5), and we may update our privacy policy in the same way. The new version is posted on its page with a new date. Where reasonable, we will tell you about a material change in the Service and/or by email before it takes effect, and may ask you to accept it. By continuing to use the Service after that notice, or after the change takes effect, you accept the changed terms. If you do not accept them, stop using the Service and delete your account.

17. General

• These terms, with the policies they name, are the whole agreement between you and us about the Service.
• We may transfer these terms to another business, for example if GreyChess is sold or reorganised. You may not transfer them.
• If any part of these terms cannot be enforced, the rest still applies. Not enforcing a part at once does not waive it.
• We are not responsible for delays or failures caused by events beyond our reasonable control.
• We may send notices to the email address on your account, or show them in the Service.

18. Contact
