TERMS OF USE

Last updated: 10 November 2026

These terms cover every GMHSC app: GMHSC Tutor (tutor.gmhsc.co.uk), GMHSC Coach (coach.gmhsc.co.uk) and the GMHSC shop (shop.gmhsc.co.uk). Where something applies to only one app, it says so.

1. Who we are

The apps are run by Graham Herstell, trading as GMHSC (“we”, “us”). Contact: support@gmhsc.co.uk.

By using any GMHSC app you agree to these terms, our Privacy Policy and our Safeguarding Policy. If you don’t agree, please don’t use the apps.

2. What the apps do

  • GMHSC Tutor uses AI to create lessons, quizzes, practice questions and diagrams on any subject, for ages 5 to adult, in more than 70 languages. Teachers and trainers can also use Teacher Mode to set lessons for a class and see results. Parents can use a Family account to set lessons for their children.
  • GMHSC Coach uses AI to help sports coaches plan drills, sessions, game-day plans and mental-skills activities.
  • The GMHSC shop is where you buy credits for the apps.

3. Your account

You sign in with Google, Apple or Microsoft. One sign-in works across all GMHSC apps. You’re responsible for:

  • keeping your account to yourself (don’t share it);
  • everything done with your account;
  • telling us straight away if you think someone else has used it.

4. Age

  • Tutor can be used from age 5. Anyone under 18 needs a parent’s or guardian’s permission, and parents and guardians are responsible for supervising how their child uses it. Schools may give pupils access under their own supervision, with parental consent where needed.
  • Coach is for people aged 14 and over who coach or help to coach. Anyone under 18 needs a parent’s or guardian’s permission.

5. Credits and payment

Free goes. New Tutor accounts get 2 free lessons. New Coach accounts get 2 free goes.

Buying credits. After that, you buy credits in the GMHSC shop. Prices on the day you buy are shown in the shop. Today they are:

App Pack Price
Tutor 50 lesson credits £9.99
Tutor Teacher & Trainer pack: 300 Teacher Mode credits £49.99
Coach 50 credits £9.99
  • Each pack is a one-off purchase for one account. It is not a subscription and doesn’t renew.
  • Credits never expire, in Tutor or in Coach.
  • Credits belong to the app they were bought for. Tutor credits can’t be used in Coach, or the other way round.
  • What things cost: a Tutor lesson (with its quiz and diagram) uses 1 credit. In Teacher Mode, making a lesson uses 1 credit (2–3 for longer quizzes), plus 1 credit for each pupil it’s sent to. Coach shows the cost on each button (for example, a drill is 1 credit and a full session is 3).
  • You’re only charged for results you get. If something goes wrong, or a request is refused for safety reasons, the credit is given back automatically.
  • Payments are taken by card through Stripe. We never see or store your card number.
  • No VAT is charged, as we are not VAT-registered.

6. Refunds

You can have a full refund within 14 days of buying a pack, as long as none of its credits have been used. After that, or once credits from the pack have been used, we don’t normally give refunds, but we look at every request fairly. Email support@gmhsc.co.uk from the email address you paid with.

When we refund a pack, its credits are taken back off your balance.

7. Using the apps properly

You must not:

  • use the apps for anything illegal;
  • try to get round our safety checks or security, or ask for harmful, illegal or inappropriate content;
  • share your account;
  • copy, take apart or reverse-engineer the apps;
  • use the apps to harass, bully or harm anyone;
  • use bots or automated tools on the apps without our permission.

8. AI-made content

Lessons, plans, drills and diagrams are made by AI (Google Gemini; Tutor’s diagrams also use Google Imagen). We work hard on quality, but:

  • AI can make mistakes. Check anything important, including exam content and anything to do with health or safety;
  • an adult should check content before it’s used with children;
  • the apps are an aid to teaching and coaching. They don’t replace teachers, coaches, qualified supervision or professional advice (medical, legal or otherwise);
  • requests and results are checked for safety and suitability for the age given. See our Safeguarding Policy.

Extra points for GMHSC Coach. Coach is a planning aid – you remain the coach in charge and responsible for the session. Before using any drill, session or game-day plan, you must:

  • check it is safe and suitable for your players’ age, ability, fitness, numbers, space and equipment, and adapt or leave out anything that isn’t;
  • carry out your usual risk assessment of the venue, playing surface and equipment;
  • follow the rules, guidance and safeguarding requirements of your sport’s governing body and your club or organisation, including supervision ratios and any checks (such as DBS) your role needs;
  • know about any injuries or medical conditions in your group, have first aid available, and stop any activity that doesn’t look safe.

The mental-side activities are there to help build confidence, focus and the ability to handle pressure. They are not counselling, therapy or medical treatment. If a player or coach is struggling with their mental health, please signpost them to a qualified professional or their GP.

9. Who owns what

  • You own what you make with the apps, and can use it for personal, teaching or coaching purposes.
  • We own the apps themselves: their design, features and the GMHSC name.
  • We give you a personal, non-transferable right to use the apps under these terms.

10. Our responsibility to you

  • The apps are provided “as they are”. We can’t promise they’ll always be available. We may pause them for maintenance, and we can’t control outages at services we rely on (such as Google Cloud or Stripe).
  • As far as the law allows, we aren’t responsible for indirect losses, lost profits or lost data, for mistakes in AI-made content, or for what happens if you rely on it.
  • Our total responsibility to you is limited to what you paid us in the 12 months before your claim, or £100, whichever is more.
  • Nothing in these terms limits your legal rights as a consumer, or our responsibility for death or injury caused by our negligence, or for fraud.

11. Ending your use

  • You can delete your account at any time (see the Help page).
  • We may suspend or close an account that breaks these terms or our Safeguarding Policy, is used for fraud or abuse, or has a chargeback or failed payment.

12. Other services we use

The apps rely on Google Cloud (hosting, database and AI), Stripe (payments) and Google, Apple or Microsoft (sign-in). Their own terms also apply when you use them.

13. Changes to these terms

If we change these terms we’ll update the date at the top, and email you about any big changes. Using the apps after a change means you accept the new terms.

14. Law

These terms are governed by the law of England and Wales, and the courts of England and Wales deal with any disputes. If you live elsewhere, your local consumer laws may also apply. If one part of these terms can’t be enforced, the rest still applies.
