Terms of use

Last updated: 23 October 2026

1. Who we are

Shimsy Maths is made by Shimsy Maths Ltd, registered in England and Wales (company number 17467830), registered office 71–75 Shelton Street, Covent Garden, London, WC2H 9JQ, United Kingdom. Contact us at support@shimsymaths.com.

These terms apply when you use the Shimsy Maths app. When you buy through Google Play or the App Store, that store's own terms also apply to the payment.

2. What's free and what you can buy

Every practice worksheet in the app is free, along with its hints, solutions and tools. So are the recap cards, the Weekly Challenge, and one topic exam in each course except Maths Challenge.

A course unlock opens the exam material for one course. That means its exam-style papers for each topic, its topic exams and its full mock papers, or, for Maths Challenge, its mock challenges. The courses are:

• KS3;
• GCSE, Foundation and Higher, which also includes the KS3 papers;
• IGCSE (Cambridge IGCSE Mathematics 0580), Core and Extended;
• AS and A-level Maths;
• AS and A-level Further Maths;
• Maths Challenge, all three levels: Junior, Intermediate and Senior.

The app always shows which course a paper belongs to, and what an unlock includes before you buy.

3. Prices and launch offers

The price is the one Google Play or the App Store shows when you buy, including any tax the store charges where you live. It's a single payment, not a subscription.

Sometimes a course has a launch price. The app shows it next to the full price, along with the date it ends, and on that date the price goes up to the full price shown. If you bought at a lower price, you keep your unlock and never pay the difference.

4. Your unlock

• Your unlock is linked to the account you bought with: your Google account on Android, your Apple Account on iPhone and iPad. You can restore it on any device that uses the same store and is signed in to that account, from Settings in the app. An unlock bought on Google Play doesn't unlock the app on an iPhone or iPad, or the other way round.
• It lasts for as long as we make Shimsy Maths available in the store you bought it from. If we ever decide to stop offering the app, we'll give reasonable notice in the app and on this website.
• We keep improving the papers and fixing mistakes. We may add new papers to a course, but we don't promise to.

5. Cancelling and refunds

Under the Consumer Contracts Regulations 2013 you'd normally have 14 days to cancel a purchase of digital content. A course unlock is supplied the moment you buy. By buying, you ask us to supply it straight away, and you accept that the 14-day right to cancel ends once the papers are unlocked.

On Android, you can ask Google Play for a refund within 48 hours of buying, straight from Google Play. After that, email us with your Google Play order number (it starts with GPA.) and we'll look at every request fairly.

On iPhone and iPad, refunds are Apple's to decide: ask at reportaproblem.apple.com. We can't give App Store refunds ourselves.

Under the Consumer Rights Act 2015, digital content must be of satisfactory quality, fit for purpose and as described. If it isn't, you're entitled to have it put right, and in some cases to a full or partial refund. Nothing in these terms takes away those rights.

6. Using the content

The questions, papers, solutions, recap cards and diagrams in the app are written by Shimsy Maths and belong to Shimsy Maths Ltd.

You may use the app and its content for your own learning, and a parent or tutor may use it alongside a learner. Please don't copy, share, sell or republish the questions, papers or solutions. If you'd like to use Shimsy Maths with a class, email us.

7. Accuracy and the grade estimate

Every question is checked carefully, but mistakes can slip through. If you think an answer is wrong, please tell us. We check every report and correct any mistake we find.

On GCSE, IGCSE, A-level and A-level Further Maths mocks and topic exams, the app shows a grade estimate. It compares your score on our own papers with averages of recent grade boundaries. It's a guide to where you stand, not an official or predicted grade. Real grade boundaries are set by the exam boards each year and depend on their papers.

8. Not affiliated with exam boards

Shimsy Maths is independent. It isn't affiliated with, endorsed by or connected to AQA, Pearson Edexcel, OCR, Eduqas, Cambridge University Press & Assessment, the UK Mathematics Trust or the Department for Education. We name them only to describe what the content covers. The questions, worked solutions and recap cards in the app are all written by Shimsy Maths.

9. Our responsibility to you

We're responsible for loss or damage you suffer that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. We aren't responsible for loss that wasn't foreseeable, or for business losses: the app is for personal use. If content we supplied damages a device or other digital content of yours because we didn't use reasonable care and skill, we'll repair the damage or pay you fair compensation.

Nothing here limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law doesn't allow us to limit.

10. Younger users

If you're under 18, please ask a parent or guardian before buying anything. Google Play's parental controls, and Apple's Ask to Buy, can require approval for purchases.

11. Changes to these terms

We may update these terms, for example when the law changes or we add a feature. Changes won't take away anything you've already bought. The date at the top shows when they last changed.

12. Law and disputes

These terms are governed by the law of England and Wales. If you live in Scotland or Northern Ireland, you can also bring proceedings in your local courts. If you live outside the UK, you also have any rights your local law gives you. If you have a problem, please email us first, as most things can be sorted out quickly.
