Terms of use

These terms set the conditions for using tinyai.run (the "Service"), operated by iroi, LLC ("we"). Only this English text is authoritative.

Article 1 (Scope)

1. These terms apply to everyone who uses the Service ("users"), including people who register AI engines, play games against AIs, watch games, write in the forum, buy signs, or use the Service through an AI agent.
2. Rules, guidelines and other provisions that we publish on the Service (together, the "specific rules") form part of these terms. Where these terms and the specific rules differ, the specific rules prevail.
3. The Service has no accounts. By using the Service you are deemed to agree to these terms. Minors must use it with the consent of a legal guardian.

Article 2 (Use through AI agents)

1. When you have an AI agent register engines or do anything else on the Service, the person or organization that instructed it is the user and is responsible for following these terms.
2. Games against AIs are for people playing in a browser. Do not start or play them with automated programs.

Article 3 (Registering engines)

1. You may register only WASM and data files for which you hold the rights to register them and to allow the use in the next paragraph.
2. You allow us to store the WASM and data files you register, to instrument them (insert code that counts instructions), and to run them in checks, gate games, official games and games against people. We do not give registered WASM or data files to any third party.
3. The license is private (the default) or one listed in the specific rules. You may license only what you hold the rights to. The license cannot be changed later.
4. A contact entered with a license other than private is shown only to sponsor companies whose sign is live, for research enquiries. By entering it you agree to this. Do not enter a contact that is not yours.
5. The token is shown once at registration and is not reissued. Keeping it is your responsibility.
6. Limits on the number and interval of registrations, the Proof of Work, the gate and other conditions follow the specific rules.

Article 4 (Published records, watching and use of records)

1. Engine names, author names, the self-declared author, licenses, sizes and SHA-256 hashes, game records (moves, time and instructions per move, search depth and score), results, ranks, ratings and power estimates are published, and stay after an engine is deleted.
2. Anyone can watch official games and games against AIs (games against people while they are played and for a short time after they end).
3. Publishing a game against an AI cannot be undone.
4. The published records are compiled and published by us. You may view them, link to them, share them with the Service's share features, and use them for personal, educational or non-commercial research purposes, including developing and testing your own engines, with a credit to "tinyai.run" and, where practical, a link.
5. You may use the records of games played by engines you registered for any purpose, with the same credit.
6. You may show, commentate on, review or quote individual games, rankings and ratings in articles, videos, streams and posts, including monetized ones, as long as you state the source as "tinyai.run" where viewers can see it (on screen or in the description or post, with a link where practical). This does not cover collecting them by automated means.
7. Unless the previous three paragraphs allow it, you need our prior written permission to: collect records by crawling, scraping or other automated means, or mirror them, whether or not within the API's limits (except reading the status and games of engines you registered, and search engines indexing pages as robots.txt allows); redistribute records, rankings or ratings as a data set or through another service; or use them commercially, including selling them, putting them in paid products or services, and using them to train or evaluate models or engines for a commercial product. Ask at hello@tinyai.run.

Article 5 (Games against AIs)

1. Starting a game on the server requires passing a human check.
2. Games against AIs do not count toward the ranking. An engine's wins against people are not a measure of strength, as a person cannot be told from a program.
3. Limits such as games at the same time and games per day follow the specific rules.

Article 6 (Buying signs)

1. Signs are for businesses (sole proprietors and side businesses included). The countries and regions we sell to are listed on the sponsor page.
2. Prices are shown in US dollars on the sponsor page, for one payment covering 30 days with no auto-renewal. Prices include consumption tax (10% for customers whose head office or home address is in Japan); customers outside Japan pay no Japanese consumption tax. If the location cannot be determined, we treat the price as including 10%. Currency conversion fees depend on your card issuer.
3. Payment is by credit card, Apple Pay or Google Pay on our payment processor's page, when you order.
4. A sign goes up as soon as you add its name and link after paying (or on the first day of the period, if you bought a later period). The dates are fixed when you buy and the last day does not move, so adding your details later means a shorter run.
5. You can cancel for a full refund within 7 days of purchase, as long as the sign has not started. After 7 days or once it has started, there is no refund, however few days it has run. If no name and link are added by the last day of the period you bought, the sign does not go up and there is no refund. A payment that overlaps another order is refunded in full.
6. A sign's name, link, logo and message must not include anything illegal, adult content, gambling, politics or religion, defamation, or other people's names or trademarks.
7. The buyer holds the rights needed for the sign's content and allows us to show it on the Service (including resizing and converting it, showing it on boards and pages, and its appearance in game videos). Videos saved by viewers keep the signs shown at that moment.
8. We audit signs after they go up. If we decide we cannot show a sign, we take it down and refund it in full, however long ago it was bought.
9. Signs have no effect on ranks, ratings or rulings.
10. A sponsor company that reads an engine's contact uses it only to contact the author about research: no sales, resale or redistribution. If this is broken, we revoke access to contacts.

Article 7 (Prohibited conduct)

Users must not:

1. break the law or public order and morals;
2. evade or deceive instruction counting, docking fees, time limits, checks, the referee or record verification (including building an engine for that purpose). If you find a flaw, tell us at hello@tinyai.run;
3. deliberately get around request limits, daily limits, the Proof of Work or the human check, for example with many networks or automation;
4. attack, overload, access without authorization, or exploit vulnerabilities in the Service's servers or network;
5. impersonate another person or us, or use another author's key;
6. use names containing inappropriate, political, religious or operator-lookalike words;
7. register or show engines, data or sign content without the rights to them, or infringe other people's rights;
8. use published records beyond what Article 4 allows;
9. post trolling, advertising, solicitation, links to outside sites, other people's personal data, or secrets (keys, tokens) in the forum;
10. do anything comparable to the above.

Article 8 (Measures we may take)

1. If we decide that a user has broken or may break these terms, we may, without prior notice, remove an engine from official games, delete a name, flag an author, take down a sign, revoke access to contacts, hide or delete forum posts, close forum threads, or restrict use of the Service. Refunds for a sign taken down follow Article 6.
2. Engines that do not pass the gate, and engines with repeated abnormal endings, are removed from official games automatically under the specific rules.

Article 9 (Changes and suspension)

1. We may stop all or part of the Service in an emergency, when the daily cost limit is reached, for maintenance or failures, or when an external service provider we rely on fails.
2. During the first period after launch (calibration), we may replace a reference engine or the link between them, and all ratings may move together.
3. We may change the Service and the specific rules, or end the Service.

Article 10 (Intellectual property)

1. Rights in the Service's software, screens and documents belong to us or their rightful owners.
2. Rights in registered engines stay with the user. We receive only the permission in Article 3.
3. We may use published records (game records, ranks, power estimates and so on) within the Service and to introduce the Service (such as share cards and videos).
4. Rights in forum posts stay with the poster, who is responsible for them. By posting, the poster allows us to store, display and copy the post within the Service, without payment. Posts are public; do not post personal data or secrets. We may hide or delete posts, and posts are deleted automatically under the specific rules (for example, threads without a reply).

Article 11 (Disclaimers)

1. Ratings and ranks are estimates on the Service's own scale. We have not measured how they correspond to human ratings and do not guarantee any correspondence. Power figures are converted from instruction counts, not measured on real hardware.
2. The Service is provided as is. We do not guarantee that the Service will be uninterrupted, free of errors, or fit for a particular purpose.
3. For damage to a user arising from using or being unable to use the Service, our liability is limited to direct and ordinary damage. This does not apply in cases of our intent or gross negligence.
4. For damage relating to the purchase of a sign, our liability is limited to the price of that sign. This does not apply in cases of our intent or gross negligence.

Article 12 (Changes to these terms)

We may change these terms under the provisions of the Japanese Civil Code on changes to standard terms. We will post the changes and the date they take effect on the Service before they take effect.

Article 13 (Contact)

Send questions about the Service to hello@tinyai.run.

Article 14 (Governing law and jurisdiction)

These terms are governed by and interpreted under the laws of Japan. The Tokyo District Court has exclusive jurisdiction in the first instance over disputes about the Service.

Article 15 (Severability)

If any part of these terms is held invalid or unenforceable by law or by a court, only that part is invalid, and only to that extent; the rest of these terms remains in effect.
