Terms of service

Last updated: 8 November 2026

TL;DR: Try everything free for 7 days. Plans renew yearly or monthly until you cancel, and you can cancel any time. If you're not satisfied within 14 days of paying for a plan or an exam pass, we'll refund you in full, even if you've used the site. Content is for your personal study; don't redistribute it. Everything's governed by English law.

1. Who these terms are between

These terms are the agreement between you (the person creating an account, buying a licence, or browsing the site) and IB Math Revision, run as a sole trader by Pete Bromfield in the United Kingdom (contact: pbromfield@ibmathrevision.com).

By clicking "Sign in", "Subscribe", "Buy" or otherwise using the site, you agree to these terms. If you don't agree, please don't use the site.

2. What we're selling

Pro plan (€99 a year or €12 a month): access to all four DP maths courses (SL AI, SL AA, HL AI and HL AA), including question banks, mark schemes, video walkthroughs generated on request, progress tracking and flashcards, plus AI marking, the AI tutor, the interactive coach and AI IA reviews.
Essentials plan (no longer sold since 13 October 2026; existing subscribers keep it at €49 a year or €5 a month): the Pro content without the AI features.
Platinum plan (no longer sold since 13 October 2026; existing subscribers keep it at €499 a year or €49 a month): everything in Pro plus priority support, and the full PDF worksheet library (included in every paid plan).
Exam pass, when offered (€79): one payment for everything in the Pro plan until 14 days after the last exam of the IB session you choose at checkout (May or November). The end date is shown before you pay and in your receipt. It does not renew. It is an alternative to a plan that renews, not an add-on: it can't be bought while an IB plan of yours is set to renew.
One-off services: AI IA feedback credits (€5), the One-to-one IA Review with Pete (€100) and personalised question sets (€5, or €20 for five).
School licence (School €790 a year for 100 students; School Unlimited €2,490 a year): Multi-seat access for a defined cohort at a school. Renews yearly until cancelled; refunds and cancelling are in section 7 of the Refund Policy. Governed by a separate Data Processing Agreement — email us if you're a school.

New accounts get 7 days of full access free, starting when they answer their first question, with no card needed. Changes apply to trials started after 8 November 2026: a free week that started earlier keeps the days it was given. Pro bought at checkout starts with a 7-day free trial if you haven't had a free period with us before (one per person across our sites: the free week, a card trial or a Founding month): your card is not charged until day 7, and cancelling before then costs nothing. Otherwise Pro starts straight away, and checkout says so before you pay. The Essentials, Pro and Platinum plans are subscriptions that renew automatically (yearly or monthly, as chosen at checkout) until you cancel. You can cancel any time from your Account page ("Manage subscription") or by emailing us; you keep access until the end of the period you've paid for, and nothing further is charged. Switching plan from your Account page is worked out pro rata by Stripe on your next bill. One-off services and exam passes do not renew. Purchases made under earlier one-off pricing (single courses, the four-course bundle, the €20 Pre-IB and Summer offers, the €39 SAT Math Prep licence and the €50 IB + SAT bundle) keep the access they were sold with. SAT Math revision is now free and is no longer sold.

3. Your account

You need an account (email + password or Google/Microsoft sign-in) to access paid content. You are responsible for keeping your login credentials secure. Don't share your account — it's licensed to one person. Under 13? You can use the site only with a parent’s or guardian’s consent, or through your school (see the Privacy Policy).

Accounts are personal: one account is for one person, and it can be used on up to 5 devices. You can remove a device on your account page (up to 3 removals in any 30 days; after that, email us and we’ll help). A 6th device is asked to remove one of the other five before it can continue. If an account looks shared, we may temporarily suspend it while we check.

4. What we promise

To keep the site running and your paid content accessible for at least the licensed period (barring short maintenance windows < 4 hours).
To only bill you for what you clicked to buy — no surprise charges, no dark patterns.
To respect your data as set out in the Privacy Policy.
To give any support email a priority response.

5. What we don't promise

A specific IB grade. Practice + effort + teaching drive grades; a website is one input among many.
That any specific question will appear on your exam. Content is examiner-style but not "leaked" past-paper content.
Bug-free software. If something breaks and it affects your access, tell us and we'll fix it.
Availability during scheduled maintenance or service outages of our underlying providers (Google Cloud, Stripe, Resend).

6. Payments & refunds

Card payments are processed by Stripe. We never see your card number. Prices displayed include EU VAT where applicable.

Our Refund Policy is part of these terms. In short:

14-day money-back: if you're not satisfied, email us within 14 days of your first payment for a plan, or of buying an exam pass or one of the one-off purchases listed there, and we'll refund you in full, even if you've used it.
Renewals: if a plan renews and you haven't used it since, email us within 14 days of the renewal payment and we'll refund it. Otherwise cancelling stops the next renewal and we don't refund part of a period.
The One-to-one IA Review with Pete: a full refund before you upload your draft; after you ask us to start, a refund within 14 days of booking is reduced by the marking already done.
School licences: business terms, set out in section 7 of the Refund Policy.

When a refund is issued, the plan or pass it paid for ends automatically. This is on top of your legal rights, including the 14-day right to cancel under UK and EU consumer law and your rights if digital content is faulty; nothing in these terms takes them away.

7a. AI IA Feedback & One-to-one IA Review with Pete — academic honesty

Both the €5 AI IA Feedback tool and the €100 One-to-one IA Review with Pete are study aids providing revision-style guidance against the published IB assessment descriptors. They are not co-authoring services.

By uploading a draft to either service you confirm that:

The draft you submit remains your own work and you retain sole authorship of your final Internal Assessment submission.
You will not paste AI-generated rewrites, suggested phrasing, or model text verbatim into your final IA.
You will disclose use of any AI tool (including this one) in your IA's declaration if your school or the IBO requires it — and you have checked what your school requires.
You understand the IBO's Academic Honesty policy and accept sole responsibility for compliance.
Feedback is provided in good faith but does not guarantee any specific grade or mark. Final examiner judgement rests with the IBO.

We reserve the right to refuse or terminate service if we reasonably believe the tool is being used to circumvent academic honesty rules (e.g. submitting an entire draft written by another AI system for us to "clean up").

7b. What you can and can't do with the content

You can:

Use every question, mark scheme and PDF for your own personal study.
Print PDFs and take them into a study session, tutor session, or exam-hall reading.
Discuss questions with your teachers or tutors.

You must not:

Redistribute, resell, publicly post, or upload questions/answers/PDFs to sharing sites (e.g. Course Hero, Discord servers, Reddit, forum sites).
Use the content to train a competing AI system, question bank, or revision product.
Scrape the site programmatically or attempt to bypass paywalls.
Reverse-engineer the AI grading prompt, mark scheme structure, or Cloud Function API.

Doing any of the above ends your licence immediately, with no refund.

7c. Independence

IB Math Revision is independent and is not affiliated with, endorsed by or connected to the International Baccalaureate Organization. This work/product/service has been developed independently from and is not endorsed by the International Baccalaureate Organization. International Baccalaureate, Baccalauréat International, Bachillerato Internacional and IB are registered trademarks owned by the International Baccalaureate Organization.

We never host IB past papers or mark schemes: we link to the official copies only. Every question, worked solution and mark scheme on the site is our own original work. Pete Bromfield’s IB examining experience is his own personal background; it does not mean the IB has reviewed or approved the site.

8. Intellectual property

Every question, mark scheme, PDF workbook, flashcard and worked solution on the site is either created by Pete Bromfield or licensed to IB Math Revision. All content is protected by UK and international copyright law. You get a personal, non-transferable licence to use it — you don't own it.

"IB Math Revision", the logo and site design are trademarks of Pete Bromfield.

9. If you're a school / teacher

A school licence covers a defined cohort of students at your school for the licensed period. Enrol students via the class-code redemption flow. Students remain data subjects under GDPR; your school is the data controller, we are the data processor. A Data Processing Agreement (DPA) is available on request — it's a legal requirement before your DPO can approve a school-wide roll-out.

10. Suspension & termination

We can suspend or close your account if you materially breach these terms (particularly section 7). Where possible we'll email you first with a chance to resolve it. If we close an account for a serious breach (e.g. content resale), no refund is due.

You can close your account at any time by emailing us — see the Privacy Policy for how we delete your data.

11. Liability

Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, fraud, or anything that can't be excluded under English law.

Subject to that, our total liability to you for any plan or licence is limited to the amount you paid for it. We are not liable for indirect losses (e.g. missed grade, university offer withdrawn, lost tutoring fees).

12. Changes to the site & terms

The site's features may change over time. We reserve the right to remove, replace or improve tools. If we make a change that meaningfully reduces what you paid for, we'll email you and offer a pro-rata refund.

If we change these terms, we'll email everyone with an active account and post the new version here. Small typo fixes just get a note at the top.

13. Complaints & dispute resolution

If something goes wrong, please just email us first — most problems are a misunderstanding we can fix quickly. If we can't resolve it, you're free to escalate to:

Your card issuer for payment disputes.
The UK Information Commissioner's Office for data-protection issues.
An English court (see section 14).

14. Governing law

These terms are governed by the laws of England and Wales. Any dispute is subject to the exclusive jurisdiction of the English courts.
