Terms of use

These terms are a binding agreement between you and Appcelerator Studio, operating from the Republic of Serbia and trading as Learn GTO. In them, we, us and Learn GTO mean that operator, you means the person using the service, and the Service means the Learn GTO website at learn-gto.com and everything offered through it.

You accept these terms by using the Service. If you do not accept them, do not use it — that is the entire mechanism, and it is the only one available on a site with no accounts to click through.

These terms incorporate our privacy policy, which explains what happens to personal data and is part of this agreement.

Words used in a particular sense throughout:

• Content — everything we publish through the Service: lessons, guidebooks, exercises, range charts, computed figures, prose, imagery, design and code.
• Reference pages — the parts of the Service open to everyone without a Plan: the equity and pot-odds calculators, the starting hand pages, the matchup library, the outs tables, the hand rankings, the glossary and the range charts.
• Plan — a paid subscription giving access to the course and the trainer.
• Early Access — the current arrangement, under which access is granted without payment. See § 10.
• Consumer — an individual using the Service wholly or mainly outside their trade, business, craft or profession.

By using the Service you confirm that:

1. you are at least 18 years old, and old enough under the law where you live to view material about poker;
2. you have the legal capacity to enter into a binding contract, and are doing so on your own behalf or with authority to bind an organisation;
3. you are not barred from using the Service under the law of any country that applies to you, including sanctions and export control law; and
4. you will not use the Service where doing so would be unlawful where you are. Establishing that is your responsibility, not ours — see § 12.

We may refuse or withdraw access to anyone who does not meet these requirements, at any time.

Learn GTO is an educational product: a Texas hold’em course, a preflop trainer that grades your decisions, and a set of calculators and reference pages. It teaches a game. That is all it does.

Learn GTO is also not financial, investment, tax, legal or professional advice of any kind, and no relationship of that sort is created by your using it.

Subject to these terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable and revocable licence to access and use the Service and the Content for your own learning.

That is a licence, not a sale. Nothing in it transfers ownership of anything, and every right not expressly granted is reserved. If we introduce accounts, your access will be personal to you and you will be responsible for keeping your credentials secure and for everything done through them.

You agree not to:

1. copy, reproduce, republish, distribute, sell, licence or otherwise exploit the Content, in whole or in substantial part, except as these terms expressly permit;
2. use the Content to build, train or improve a competing product, or as training data for a machine learning model, except as § 7 permits;
3. scrape, harvest or bulk-download the Service by automated means, except as § 7 permits;
4. circumvent, disable or attempt to defeat any paywall, entitlement check, access control or usage restriction, or share access with anyone else;
5. reverse engineer, decompile or disassemble any part of the Service, except to the precise extent that applicable law grants you a right to do so which cannot be excluded by contract, such as the interoperability rights under Article 6 of Directive 2009/24/EC;
6. interfere with the Service or its infrastructure, including by denial-of-service attacks, injecting malicious code, or probing or testing its security without our written permission — good-faith vulnerability reports to team@learn-gto.com are welcome and are not a breach of this clause;
7. remove, obscure or alter any copyright, trade mark or other proprietary notice; or
8. use the Service for anything unlawful, or in any way that could damage, disable or overburden it, or expose us to liability.

§ 6 would, read alone, forbid the crawling that keeps this site findable. It is not read alone. Our robots.txt file is the machine-readable statement of what we permit, it is deliberately permissive, and it prevails over the general prohibitions above to the extent of any conflict.

It grants search engine and answer engine crawlers — including AI crawlers, named individually and on purpose — access to the public reference pages, so that they may be indexed, quoted and cited. Our reference content is free, factual and meant to be quoted. What we do not permit is the wholesale reproduction of the Content as a substitute for the Service, or bulk extraction beyond what robots.txt allows.

For clarity, and for the purposes of Article 4(3) of Directive (EU) 2019/790: our permissions for text and data mining are exactly those expressed in our robots.txt at the time of access, and all rights beyond them are expressly reserved.

The Service and the Content are owned by Appcelerator Studio or our licensors, and are protected by copyright, database rights, trade mark law and the law of unfair competition. “Learn GTO”, our wordmark and our visual identity are our trade marks; you may not use them without our written permission, except to refer to us accurately.

What we do not claim is worth stating precisely, because a clause that overreaches here invites the whole document to be read sceptically. The rules of poker are not ours. Neither is the mathematics: the probability that one hand beats another is a fact about a deck of cards, it existed before us, and no one can own it. What we own is the expression — the course, the prose, the exercises, the design, the code, the selection and arrangement of what is presented and the way it is explained.

You are welcome to quote short extracts and individual figures with attribution and a link. You may not reproduce a lesson, a unit or a substantial part of the reference library.

The Service has no facility for publishing anything you write, so there is no user content to license to us. If that changes, this clause changes with it before the feature ships.

If you send us feedback, suggestions or ideas about the Service, you grant us a perpetual, irrevocable, worldwide, royalty-free licence to use them without restriction and without owing you anything. We are not trying to take your ideas; we are avoiding the situation where a suggestion we had already planned becomes a claim. If that is not acceptable to you, please do not send us suggestions.

The Service links to sites we do not control, and some of those links may earn us a commission if you sign up or buy. We do not endorse, and are not responsible for, anything on a site we link to; your dealings with them are between you and them. A commercial relationship never changes the arithmetic on this site — equity figures are computed from the cards, not from who is paying — and it never changes what we teach.

We aim to keep the Service available and working, but we do not promise it will be uninterrupted, timely, error-free or available at any particular level. It may be unavailable for maintenance, for reasons at our hosting provider, or for reasons outside anyone’s control.

We may change, add to, or remove features. Where a change would materially reduce what a paid Plan gives you, we will give reasonable notice and, if you do not accept it, you may cancel and receive a refund of the unused part of your current period. We may discontinue the Service entirely, in which case we will give as much notice as is reasonable and refund unused paid periods.

If you are a Consumer, this clause does not affect your statutory rights. Where the law of your country gives you rights in respect of services that are not of satisfactory quality, not fit for purpose or not as described, you keep those rights in full, and nothing here excludes or limits them.

What this clause does not do. Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, or for any other liability that cannot lawfully be excluded or limited. If you are a Consumer, nothing here excludes or limits liability that the law of your country of residence does not permit to be excluded or limited, and to the extent any part of this clause is unenforceable against you, it does not apply to you.

You accept that the limits above are a reasonable allocation of risk between us, and that they are part of what makes the Service available on the terms it is available on.

If you use the Service in breach of these terms or unlawfully, you will indemnify us against claims, losses, liabilities and reasonable legal costs arising from that use. We will tell you promptly about any claim, will not settle it without your agreement, and will let you control the defence if you confirm you will cover it. This clause does not apply to a Consumer except to the extent the law of your country permits.

You may stop using the Service at any time. To remove everything held on your device, clear site data for this domain in your browser — that is immediate and total, and needs nothing from us.

We may suspend or terminate your access if you materially breach these terms, if we are required to by law, or if continuing would expose us or other users to risk. Where it is reasonable to do so we will warn you first and give you a chance to put it right. If we terminate a paid Plan for any reason other than your breach, we refund the unused part of what you paid.

Clauses that by their nature should survive termination do survive it, including § 8, § 9, § 15, § 16, § 17, § 20 and § 23.

We are not liable for any failure or delay in performing our obligations caused by something beyond our reasonable control, including natural events, war, civil unrest, epidemic, government action, strikes, failures of the internet, of a hosting or payment provider, or of telecommunications or power networks. If such an event continues for more than 30 days, either of us may terminate a paid Plan and we will refund the unused part.

These terms, and any dispute arising out of or in connection with them or the Service, are governed by the laws of the Republic of Serbia, without regard to its conflict of laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. Subject to the paragraph below, the courts of the competent courts of Belgrade, Republic of Serbia have exclusive jurisdiction.

Consumers in the European Union, the European Economic Area and the United Kingdom may also be entitled to refer a dispute to an alternative dispute resolution or ombudsman body in their own country. We are not obliged to use any particular ADR body and are not currently signed up to one, but we will engage constructively with any competent body you take a complaint to.

Before starting formal proceedings, please email team@learn-gto.com setting out what has gone wrong and what you want done about it. We undertake to respond substantively, and to try in good faith to resolve it, within 30 days. Most disputes end there, faster and at less cost than any alternative.

This is a request, not a condition. It does not stop you going to a court or a regulator whenever you choose, does not extend any limitation period, and does not prevent either of us from seeking urgent injunctive relief.

Claims are brought individually. Neither of us will bring a claim against the other as a representative or member of a class or collective action, except where the law of your country gives you a right to participate in collective redress, which this clause does not affect.

We may change these terms. The version number and the date at the top of this page change in the same release as the change itself; the version you are reading is 2.1.

For a change that materially affects your rights or obligations, we will give reasonable notice before it takes effect — by email where we have your address, and by a prominent notice on the site otherwise. Continuing to use the Service after a change takes effect means you accept it; if you do not, stop using the Service, and if you hold a paid Plan you may cancel and receive a refund of the unused part of your current period. Changes never apply retrospectively to a dispute that has already arisen.

• Entire agreement. These terms and the privacy policy are the whole agreement between us about the Service, and replace anything said or written before. Nothing here excludes liability for fraudulent misrepresentation.
• Severability. If any provision is held unenforceable, it is severed or read down to the minimum extent necessary and the rest continues in force.
• No waiver. Not enforcing a right on one occasion does not waive it.
• Assignment. You may not assign or transfer your rights under these terms. We may assign ours to a successor in connection with a merger, acquisition or sale of assets, provided your rights are not reduced.
• No partnership. Nothing here creates a partnership, agency, employment or joint venture between us.
• Third parties. Nobody other than you and us has any right to enforce these terms.
• Notices. We give notice to you by email where we have an address, and otherwise by publishing it on the Service. You give notice to us at team@learn-gto.com.
• Language. These terms are written in English. Any translation is provided for convenience, and the English version governs in the event of a conflict — except where the law of your country requires otherwise.
• Headings. Clause numbers and headings are for navigation and do not affect interpretation.

Every question, notice, complaint or legal communication goes to team@learn-gto.com, and reaches us wherever we are established.
