Terms of Service

Last updated: 2026-10-13

1. Acceptance of Terms

By accessing or using MathPrepAI (the “Service”), you agree to be bound by these Terms of Service. If you disagree, you may not use the Service.

2. Account Registration

You must provide accurate information and keep your account credentials secure. You are responsible for all activity that occurs under your account.

3. Student Data & the Basis for Holding It

3.1 Which set of rules applies to you

Section 3 comes in two versions, depending on who our customer is. (a) Individual educator route — you signed up and pay in your own name, whether you are a teacher, lecturer, private tutor, or parent; sections 3.2 and 3.3 apply to you. (b) Institutional route — a school, agency, or other legal entity is our direct customer and has signed a Data Processing Agreement with us; section 3.4 applies. If you are not covered by an institutional agreement under (b), you are always on route (a) — even if you teach at a school, are employed by one, or use MathPrepAI with that school's students. Your school knowing about or supporting your use of MathPrepAI does not make the school our customer.

3.2 Route (a) — your role and ours

When you create a class and enter student information, you are the data controller for that student data, and MathPrepAI acts only as your data processor — we store and process it on your instructions, solely to provide the classroom features, and never for our own purposes. We do not use it to train models, to market, to profile, or to sell. Because you are the controller, you are responsible for having a lawful basis to collect and use that data, and for giving parents or students whatever notice the law requires. We are built to hold as little student data as possible: a school-level class stores only a display name and class membership — no email, photo, date of birth, address, phone number, or student ID for a child.

3.3 Route (a) — consent for students who are minors

Before a student who is a minor (see 3.5) can sign in, you must have one of the following bases, record in the product which one you are relying on, and keep your own evidence of it.

(1) Consent from each individual parent or guardian — the primary basis, and the only one available if you are not acting within a school. You must obtain consent from each student's parent or legal guardian in advance, using our consent flow — where the parent confirms through a link sent to their own email address, and consent is recorded only when that link is clicked — or by another method you can evidence and retain. A parent may withdraw consent at any time; once withdrawn, that student can no longer sign in. This basis applies to private tutors, parents teaching their own children, teachers running classes outside a school, and all independent educators.

(2) Authorisation from a school — available only if you are acting within a school. If you are a teacher acting within a school, and that school has authorised you to use digital tools with its students, you may instead rely on the school's own lawful basis. In that case you must name the school and confirm that: (i) the school knows about and permits the use of MathPrepAI with its students; (ii) the school has its own lawful basis for processing student data and has given parents the notice the law requires; and (iii) use is limited to educational purposes only. We may ask you to evidence that authorisation, and may suspend your students' access if you cannot produce it within a reasonable time.

Basis (2) is the weaker one and its scope differs by country. We recommend basis (1) wherever it is workable, and if the school wishes to take responsibility itself, the institutional route in 3.4 is the clearest way to do so. You may change or withdraw a basis-(2) attestation at any time from your dashboard. Once withdrawn, students who do not have an individual guardian consent on record can no longer sign in; students who do have one continue as normal.

3.4 Route (b) — schools and institutions as our customer

A school, agency, or other legal entity can be our direct customer. In that case the school is the data controller for all student data in classes covered by that agreement, and MathPrepAI is the data processor, acting on the school's documented instructions. The school chooses and is responsible for its own lawful basis — which may be a legal obligation, a public task, performance of a contract, legitimate interests, or consent, as the case may be. MathPrepAI does not choose a lawful basis on a school's behalf and does not warrant that any particular basis is available to it. The school gives students and parents the notices the law requires, and manages parental consent where the law requires it. Teachers the school authorises to use the Service act on the school's behalf. The terms between us and the school are set out in our Data Processing Agreement; where that agreement conflicts with these Terms, the Data Processing Agreement prevails on data-protection matters. Institutional plans are not yet available for self-service purchase — please contact legal@mathprepai.com for an agreement and a quote.

3.5 Who counts as a minor — the ages we apply

In these Terms, “minor” means a person who has not reached the age of legal majority, or has not reached the age at which they may consent to the processing of their own personal data, under the law that applies to that student. Where more than one standard applies, we apply the strictest.

Thailand — a person reaches legal majority at 20 years of age, or upon a lawful marriage (Civil and Commercial Code, sections 19 and 20). Every Thai student from kindergarten through Mathayom 6 is therefore a minor. Under section 20 of the Personal Data Protection Act B.E. 2562, consent concerning a minor's personal data requires the consent of the person exercising parental power; where the minor is 10 years old or younger, consent must be obtained from that person alone. The number 13 is a United States standard, not a Thai one — a student being older than 13 does not switch off 3.3.

United States — children under 13 are covered by the Children's Online Privacy Protection Act (COPPA), which requires verifiable parental consent before their personal information is collected. European Economic Area and United Kingdom — the age at which a child can consent for themselves to an information-society service is between 13 and 16, depending on the country (GDPR Article 8); below that age, the holder of parental responsibility must consent. Elsewhere — the age standard of the student's own country applies; if you are unsure, treat the student as a minor.

How this works in the product: classes you create as School (K-12) or Secondary treat every student as a minor regardless of actual age, and will not let a student sign in until a basis under 3.3 exists. Higher-education classes are designed for adult students: a joiner verifies their own email with a one-time passcode and affirms they are 18 or older, and anyone who does not affirm this is treated as a minor and requires a basis under 3.3. That affirmation, however, is not by itself a lawful basis — in countries where majority is reached above 18, such as Thailand, the lawful basis for the educational relationship still comes from the institution or the educator under 3.2 or 3.4.

3.6 Classes that sign in with email or a Google account

If your class enables email or Google sign-in (secondary or university classes), whoever is responsible under 3.2 or 3.4 remains solely responsible for having a lawful basis to collect and process those students' email addresses, for obtaining any consent required for minors, and for verifying student identities. Email verification is not consent: secondary students are still minors and still require a basis under 3.3, exactly as school-level classes do. When a student chooses to sign in with a Google account, their sign-in data is also processed by Google under Google's own terms. MathPrepAI provides the tools; the decision to enable email sign-in and the associated consent obligations rest with you or your institution.

3.7 Parent and student rights

A parent or guardian may at any time ask you or us to review, correct, or delete their child's data, or to stop further collection, by contacting you directly or emailing privacy@mathprepai.com. When consent is withdrawn or a student is removed from a roster, the student's access ends immediately and their data is deleted or de-identified per our retention policy. Because you (or your institution) are the controller for the class, a student's or parent's request is routed to you, and we assist as the law requires. See our Privacy Policy for how children's data is handled.

4. Usage Limits & Quota

Free accounts may generate up to 30 worksheets per month; the counter resets on the first day of each calendar month. Paid subscribers may generate an unlimited number of worksheets each month. Storage quota (number of worksheets saved in your cloud library) varies by plan: Light 500, Teacher 2,000, Creator Lite 500, Parent 2,000, Creator unlimited. New accounts receive a 14-day Founder Pass granting full Creator-level access at no cost; access reverts to the Free tier at expiry.

You may cancel any time; access continues until the end of the current billing period. Within the first 7 days of an initial subscription, you may request a full refund. See the Refund Policy for Feature Pass and Lifetime refund terms.

6. Acceptable Use

You agree not to: misuse the Service, attempt to reverse-engineer it, share account credentials, or use generated content for unlawful purposes.

Bring-your-own AI keys. Some features (AI-assisted question authoring and grading) require you to supply your own third-party AI provider API key. You are solely responsible for that key, for all usage charges the provider bills to it, and for complying with that provider’s terms. MathPrepAI merely relays your requests using your key; we do not cover, refund, or control provider costs, and we are not liable for the AI provider’s output or availability.

7. Intellectual Property

You own the worksheets you generate. The mathematical problems themselves are facts and not subject to copyright. The MathPrepAI platform, generators, algorithms, source code, worksheet templates, clip-art icons, name, and branding remain our exclusive property. Your right to use our assets inside the worksheets you create is governed by the Commercial License (Section 8) and the Our Icons & Fonts terms (Section 9).

8. Commercial License (Creator Lite tier and above)

Subject to an active Creator Lite-tier (or higher) subscription, we grant you a worldwide, non-exclusive, royalty-free license to reproduce, print, distribute, publicly display, and sellthe worksheets you generate (each an "End Product"), including on marketplaces such as Amazon KDP, Teachers Pay Teachers, and Etsy, and through your own store or website. There is no per-unit sales limit.

Plan limits. The Free, Light, Teacher, Parent, and Student plans are for personal, home, and classroom use only; selling or commercially distributing worksheets is not permitted on those plans. Only the Creator Lite tier and above include commercial resale rights.

Survival. End Products you lawfully created and sold while on an eligible plan may continue to be used by their buyers after your subscription ends; your right to create and sell new End Products ends when your eligible plan lapses or these Terms are breached.

Provenance.Worksheets generated by the Service may carry an embedded, non-personal reference identifier so a file's origin can be verified in a dispute. You agree not to remove or alter this identifier.

9. Our Icons & Fonts

The clip-art icons we provide are original artwork created by MathPrepAI. The fonts we provide are open-source fonts licensed under the SIL Open Font License 1.1 or Apache License 2.0, which permit commercial use and embedding in PDF files. We sublicense these assets to you solely as they are incorporated into your End Products.

You may not: (a) extract, resell, redistribute, or sublicense our icons, fonts, or templates as standalone files or as a clip-art, asset, or template bundle; (b) sell an End Product whose primary value is our raw assets rather than the worksheet content; (c) distribute any font file on its own; (d) resell, sublicense, or reverse-engineer the MathPrepAI platform, generators, or algorithms; or (e) use the MathPrepAI name, logo, or marks without our written permission.
