Terms of Service

These Terms of Service ("Terms") are an agreement between you and [operator's legal name — to be completed] ("PolyGoft", "we", "us"). They apply to the PolyGoft website, the PolyGoft app for iPhone and iPad, and everything offered through them (together, the "Service"). By creating an account or using the Service you agree to these Terms. If you do not agree, please do not use the Service.

Our Privacy Policy explains what information we collect and how we use it. It is part of how the Service works, and we ask you to read it alongside these Terms.

1. What PolyGoft is

PolyGoft helps people learn Persian (Farsi). It offers a written curriculum, lessons and practice exercises, a conversational tutor, spoken-language practice, spaced review, illustrated stories, and lessons created for you on request by artificial-intelligence ("AI") models. Much of what you see is produced or graded by AI. Section 5 explains what that means for you.

We are continually improving the Service. Features may be added, changed or removed, and parts of the Service may be offered as previews or tests that behave differently from the rest.

2. Who may use the Service

• You must be at least 13 years old. If you are under the age at which you can legally agree to these Terms where you live (18 in many places), you may use the Service only with the permission of a parent or guardian who agrees to these Terms on your behalf.
• You may not use the Service if we have previously closed your account for breaking these Terms, or if applicable law — including export-control and sanctions law — prohibits us from providing the Service to you.

3. Your account

• Keep it yours. An account is for one person. Give us accurate information when you sign up, choose a strong password, keep it confidential, and tell us promptly if you think someone else has used your account. You are responsible for what happens under your account.
• E-mail. We use your e-mail address to operate your account — for example to reset your password — and, unless you turn it off in Settings, to send you a periodic summary of what is due for review.
• Staff accounts. Accounts with access to our staff tools are issued by invitation only and are subject to additional internal rules.

4. Deleting your account

You can delete your account at any time from Settings, on the website and in the app. Deletion is immediate and cannot be undone. When you delete your account we remove your name, e-mail address, password and profile details and any stored recordings of your voice, sign you out everywhere, and close the account permanently. Your learning activity and the lessons you generated are kept without your name or e-mail address, as described in the Privacy Policy, which also explains how to ask us to erase text you typed.

5. AI-generated content — please read this

• It can be wrong. Lessons, translations, transliterations, corrections, grades, explanations, audio, images, and cultural or travel notes may be generated by AI. AI output can be inaccurate, incomplete, outdated or inappropriate, and two people asking the same thing may get different answers. We work to make it good; we do not promise it is correct.
• It is for learning. The Service is an educational tool. Nothing in it is professional advice — legal, medical, financial, immigration, safety or otherwise. Information about real places, customs, prices, opening hours or travel is provided to make language practice realistic. Do not rely on it to plan or take a journey; check official and current sources.
• Grades are feedback, not certification. Levels, scores and progress measures describe your activity in PolyGoft. They are not a recognised language qualification.
• How it works. To produce this content, what you type and say in the Service is sent to AI providers that process it on our behalf. The Privacy Policy names them and explains what is sent. Please do not put sensitive personal information — yours or anyone else's — into lessons, chats or answers.
• Tell us. If something is wrong or offensive, use "Report a problem" on the exercise, or contact us. Reports are reviewed by people.

6. What you create

"Your content" means what you submit to the Service: what you type and say, the choices and requests you make when a lesson is generated for you, the username you choose, and reports you send us.

• You keep what is yours. As between you and us, you retain any rights you have in your content.
• What you allow us to do. You grant us a worldwide, non-exclusive, royalty-free, transferable and sub-licensable licence to host, store, reproduce, adapt, translate, analyse, display and distribute your content for the purposes of operating, securing, studying and improving the Service. This includes sending it to the service providers named in the Privacy Policy and using it, with your name and e-mail address removed, to evaluate and improve how the Service teaches. This licence continues for content that remains in the Service after your account is deleted, as described in section 4.
• Lessons generated for you. When you ask PolyGoft to generate a lesson, a mission or a journey, the result is produced by our systems and AI providers from your request and from our curriculum. To the extent any rights exist in that material, they belong to us, and it is part of the Service. You may use it within the Service for your own learning under the licence in section 9.
• The shared lesson pool. Every lesson generated in PolyGoft is added automatically to a pool from which it may be recommended to other learners, who receive their own copy. A lesson is shown without your name unless you choose to be credited, in which case it shows your username. If you edit a lesson, the edited version is shared only after our staff have reviewed it. We may decline, withdraw or remove any lesson from the pool. Lessons stay in the pool, without your name, if you delete your account.
• Usernames and standings. We give you a username when you sign up, and you may choose another in Settings. It is visible to other learners on a lesson you are credited on and on the publishers' board, together with a standing derived from how useful other learners found your lessons. Do not use a name that impersonates someone, that is offensive, or that contains personal information you do not want to be public; we check the names people choose and may refuse or change one.
• Feedback. If you send us ideas or suggestions, we may use them without restriction or payment.
• Your promises about your content. You confirm that you have the right to submit your content and that it does not break the law or these Terms.

7. Acceptable use

You agree not to, and not to help anyone else to:

• use the Service to create, request or share content that is unlawful, hateful, harassing, sexually explicit, exploitative of children, or that promotes violence or self-harm;
• submit other people's personal information, or content you have no right to share;
• attempt to bypass, probe or overload the Service's safeguards or limits, including usage allowances, rate limits, content filters and access controls;
• extract the instructions given to our AI models, use the Service to build or train a competing model or product, or resell access to it;
• copy, scrape or bulk-download lessons, audio, images or other material, or use automated means to operate accounts, except as we expressly allow;
• reverse engineer, decompile or interfere with the Service, or introduce malicious code;
• impersonate another person or misrepresent your affiliation; or
• use the Service in breach of any law that applies to you, including export-control and sanctions law.

We may review content and activity for compliance with these Terms, and we may remove content or restrict access where we reasonably believe they have been broken. We are not obliged to monitor the Service.

8. Energy and usage limits

Generating content with AI costs us money each time. PolyGoft therefore shows an estimate in "Energy" on actions that use AI, and may apply allowances and limits to how much you can generate, how much audio you can request and how often you can be graded in a period. Energy is a measure of use inside the Service. It is not money, has no cash value, cannot be bought, sold, transferred or redeemed, and may be changed, reset or withdrawn at any time. Points, tiers and standings shown in the Service are of the same nature.

The Service is currently offered free of charge. If we introduce paid features we will present their price and terms before you are charged, and those terms will apply in addition to these.

9. Our content and our rights

The Service — including the curriculum, lessons, exercises, explanations, recorded and synthesised audio, illustrations, comics, software, design, names and logos — belongs to us or to those who license it to us, and is protected by intellectual-property laws. The stories retold in our comics draw on the Shahnameh, a work in the public domain; our adaptations, text and artwork are our own.

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use the Service for your own, non-commercial language learning, in line with these Terms. All rights not expressly granted are reserved.

10. Third-party services and links

The Service relies on third-party providers, which are named in the Privacy Policy, and may link to third-party websites and apps such as maps. We do not control third-party sites and are not responsible for their content or practices. Your use of them is governed by their own terms.

11. If you downloaded the app from Apple's App Store

These Terms are between you and us, not Apple. Apple is not responsible for the app or its content. Your licence to use the app is limited to Apple-branded devices you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. Apple has no obligation to provide maintenance or support for the app. If the app fails to conform to any applicable warranty, you may notify Apple, which may refund any purchase price you paid for the app; to the maximum extent permitted by law, Apple has no other warranty obligation regarding the app. Apple is not responsible for addressing claims relating to the app or your possession or use of it, including product-liability claims, claims that the app fails to conform to a legal or regulatory requirement, consumer-protection or privacy claims, or claims that the app infringes a third party's intellectual-property rights. You confirm that you are not located in a country subject to a United States Government embargo or designated by it as a "terrorist supporting" country, and that you are not on any United States Government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

12. Suspension and ending

• You may stop using the Service at any time and may delete your account as described in section 4.
• We may suspend or close your account, or limit features, if we reasonably believe you have broken these Terms, if we are required to by law, or if your use creates risk or harm for other learners, for us or for our providers. Where it is reasonable to do so we will tell you why.
• We may discontinue the Service or any part of it. If we discontinue the Service entirely we will try to give reasonable notice.
• Sections 5 to 9 and 13 to 16 continue to apply after your account or these Terms end.

13. Disclaimers

The Service is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, whether express, implied or statutory, including implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the Service will be uninterrupted, secure or free of errors, that content generated by AI will be accurate or suitable, or that any particular learning result will be achieved.

14. Limitation of liability

To the fullest extent permitted by law, we and our officers, employees, contractors and providers will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data or goodwill, arising out of or related to the Service or these Terms, however caused and under any theory of liability. Our total liability for all claims arising out of or related to the Service or these Terms will not exceed the greater of the amount you paid us for the Service in the twelve months before the claim arose and one hundred US dollars (US$100).

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under the law that applies to you — for example liability for death or personal injury caused by negligence, for fraud, or under mandatory consumer-protection law. If you are a consumer, you keep the rights that the law of the country where you live gives you and that cannot be waived by agreement.

15. Your responsibility to us

To the extent permitted by law, you agree to indemnify us against claims, losses and reasonable costs brought by a third party and arising from your content, from your breach of these Terms, or from your breach of any law or of someone else's rights. This does not apply to consumers where the law of their country does not permit it.

16. Governing law and disputes

These Terms are governed by the laws of [governing law — to be completed by counsel], without regard to its conflict-of-laws rules. The courts of [venue — to be completed by counsel] have exclusive jurisdiction over any dispute arising out of or related to these Terms or the Service, except that if you are a consumer you may also bring proceedings in the courts of the country where you live, and nothing in these Terms takes away the protection of that country's mandatory law. Before starting formal proceedings, please contact us and give us thirty days to try to resolve the matter with you.

17. Changes to these Terms

We may update these Terms as the Service and the law change. The version and effective date appear at the top of this page. If a change is material we will give you notice that is reasonable in the circumstances — for example by e-mail or in the Service — before it takes effect. If you continue to use the Service after the effective date, you accept the updated Terms. If you do not agree, you may delete your account.

18. General

• These Terms, together with the Privacy Policy and any additional terms we present for a specific feature, are the entire agreement between you and us about the Service.
• If a provision is found unenforceable, the rest of the Terms remain in effect, and the provision will be enforced to the extent the law allows.
• If we do not enforce a provision, that is not a waiver of our right to do so later.
• You may not transfer your rights or obligations under these Terms without our consent. We may transfer ours to an affiliate or in connection with a merger, acquisition or sale of assets, subject to the Privacy Policy.
• These Terms do not give rights to anyone other than you and us, except as stated in section 11.
• These Terms are written in English. If we provide a translation, the English version prevails to the extent the law allows.
