These terms govern the use of the Roko app and its website rokochess.com (together, "Roko"). They are short and plain on purpose. By installing or using Roko you accept these terms and the Privacy Notice. If you do not agree, do not use it.
1. Who provides Roko
Roko is provided by Jose Adrian Rubiera Núñez ("we", "us"), located at Ave Camino de los Parques 3880, Zapopan, Jalisco, 45133, Mexico, contact joseadrianmanutd@gmail.com.
2. What Roko is
An app for learning chess, designed for children aged 3 to 12 and meant to be used on an adult's device. It includes lessons, challenges, games against computer opponents, minigames and a companion to customize.
It is educational and entertainment material, not a promise of results. We do not state or imply that your child will reach any particular level, score or school performance within any time frame. The "strength" figures shown in the app are an in-app estimate, not an official rating from any federation.
3. Who accepts these terms
Roko is installed, set up and managed by an adult — a parent, guardian or teacher — who accepts these terms on their own behalf and on behalf of the children in their care, and who is responsible for the children using it in line with them.
If you are a minor, a responsible adult must do this for you. Children use Roko under the supervision of that adult.
Teachers and schools: you may use Roko with your students in class. By doing so, you confirm that the school or the parents have authorized you to use educational apps with them, and we ask that you do not create an account with student data: the whole app works without one.
4. License
We grant you a personal, limited, non-exclusive, non-transferable and revocable license to download Roko from an authorized store (App Store or Google Play) and use it on devices you own or control, for personal, family or non-profit educational purposes.
This license does not transfer ownership of anything to you. Everything not expressly granted here is reserved.
5. Your account
- The account is optional: the whole app works without it.
- If you create one, it is yours (the adult's), not the child's. You are responsible for keeping your sign-in methods (your Apple, Google or email account) secure.
- Tell us if you believe someone accessed your account without permission.
- You can delete it whenever you want from Parents' Area → Delete data, or by asking at rokochess.com/en/delete-account. Deletion cannot be undone.
- Accounts unused for 24 months are deleted, as explained in the Privacy Notice.
6. Acceptable use
Use Roko for what it is for: learning and playing chess.
You may not:
- Copy, modify, decompile, disassemble or reverse engineer the app, except to the extent the law expressly allows.
- Redistribute, resell, rent or sublicense the app or its content.
- Extract content (lessons, texts, illustrations, voices, animations, sounds, exercise collections) manually or automatically to use it outside Roko, or to train artificial intelligence models.
- Try to bypass the parental gate, technical limits or security measures, or access other accounts' data.
- Interfere with our servers or send them automated or tampered traffic.
- Use Roko to break the law or infringe the rights of others.
7. User-generated content
There is none. Roko does not let anyone write, upload or share anything: there is no chat, no comments, no free-text names, no profile photo and no social features. Profile nicknames are chosen from a fixed list.
If you send us suggestions or feedback through support, we may use them to improve Roko without owing you anything for it, and without using your personal data for anything other than replying to you.
8. Intellectual property
Roko, its name, logo, characters (Roko the raccoon, the companions and the opponents), texts, illustrations, animations, voices, sounds, lessons and code belong to us or our licensors and are protected by intellectual property laws.
Some components belong to third parties and are used under their own licenses, including chess puzzles derived from the Lichess database (public domain, CC0), the Patricia chess engine (MIT license) and the Nunito typeface (SIL Open Font License 1.1). The full list is at rokochess.com/en/licenses and in the app, under Parents' Area → About.
9. Price, purchases and subscriptions
Today Roko is free to download and has no in-app purchases.
If we offer paid content in the future, it will be bought through your device's store (App Store or Google Play), always behind the parental gate, and you will see the price before buying. Billing, renewals, cancellation and refunds are governed by each store's terms; refunds are requested from Apple or Google. Because digital content is delivered immediately, the right to cancel the purchase may not apply once the download has started, to the extent the law allows.
10. Third-party links and services
The app has no links a child can open alone. Links to the store or to this website sit behind the parental gate. We are not responsible for the content or practices of third-party sites or services (for example, app stores or Apple's and Google's sign-in services), which have their own terms.
11. Healthy use
Roko is designed for short sessions and does not use mechanics to stretch screen time. Even so, we recommend staying with younger children, mixing app time with other activities and following your pediatrician's screen-time advice.
If a child has ever had seizures or light sensitivity, consult a health professional before using any game or app with animations. The app respects the device's reduce motion setting.
12. Availability and changes to the service
We do our best for Roko to work well, but we do not guarantee that it will be error-free or available without interruption. The part that needs no connection — which is almost all of it — will keep working even if our servers are unavailable.
We may update, change or remove features or content to improve the app, or for technical or legal reasons. If we ever stop offering cloud sync, we will give you reasonable notice; progress saved on your device remains yours.
13. Warranties and liability
Roko is provided "as is" and "as available". To the extent the law allows, we give no warranties beyond those the law makes mandatory.
To the extent the law allows, we are not liable for indirect damages, lost profits, loss of data you kept only on your device, or damage caused by using Roko in breach of these terms. Our total liability to you for any claim related to Roko is limited to the amount you paid for it in the last twelve months (today, zero) or, if greater, the minimum amount the law does not allow us to exclude.
Nothing here limits the rights you have under consumer protection laws, including Mexico's Federal Consumer Protection Law and those of your country of residence, or our liability for willful misconduct or gross negligence.
14. Suspension and termination
You can stop using Roko whenever you want: just uninstall it, after deleting your data from Parents' Area → Delete data if you wish.
We may suspend or close access to the account features if they are used in breach of these terms or the law, or if necessary to protect other users or our systems, giving notice when possible and reasonable.
On termination, the license in section 4 ends. Sections that by their nature should survive (intellectual property, liability, governing law) remain in force.
15. Additional terms for Apple's App Store
If you downloaded Roko from Apple's App Store:
- These terms are between you and us, not Apple. We, not Apple, are responsible for Roko and its content.
- The license in section 4 lets you use Roko on Apple-branded products you own or control, as permitted by the Usage Rules in Apple's Media Services Terms and Conditions.
- Apple has no obligation whatsoever to provide maintenance or support for Roko. We provide support at joseadrianmanutd@gmail.com.
- If Roko fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price, if any. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to Roko.
- We, not Apple, will address any claims by you or a third party relating to Roko or its use, including product liability claims, claims that it fails to meet legal or regulatory requirements, and consumer protection or privacy claims.
- If a third party claims that Roko infringes their intellectual property rights, we, not Apple, will be responsible for the investigation, defense, settlement and discharge of that claim.
- You represent that you are not located in a country subject to a U.S. Government embargo and are not on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms, and upon your acceptance Apple will have the right to enforce them against you as a third-party beneficiary.
16. Changes to these terms
We may change these terms to reflect changes in the app or the law. If we do, the date and version at the top will change and we will publish the new version at rokochess.com/en/terms. The in-app text ships inside the app, so it does not change without an update. If the change is significant, we will tell you in the app. If you keep using Roko after the change, you accept the new version; if you do not agree, you can stop using it and delete your data.
17. Governing law and disputes
These terms are governed by the laws of the United Mexican States. For any dispute, the parties submit to the competent courts of the provider's domicile, without prejudice to your right, as a consumer, to go to Mexico's Federal Consumer Protection Agency (PROFECO) or to the courts and consumer protection rules of your country of residence, which continue to apply whatever we say here.
Before any claim, please write to us: almost everything can be solved with an email.
18. Other provisions
- If any part of these terms is invalid, the rest remains in force.
- Not enforcing something at a given time does not mean we waive it.
- You may not assign these terms to anyone else; we may assign them to whoever continues to provide Roko, keeping your rights intact.
- These terms and the Privacy Notice are the entire agreement between you and us regarding Roko.
- They exist in Spanish and English. If they differ, the Spanish version prevails.
