Terms of Use
Last updated 18 August 2026
These terms govern your use of Double Mark. By using the site you agree to them. If you don't agree, please don't use the service. Double Mark is a study tool that marks practice exam answers against published assessment objectives.
The most important points
- Double Mark gives an informed estimate, not an official grade. It is not affiliated with any exam board and is not a substitute for a teacher.
- Feedback can be wrong or incomplete — don't rely on it for important decisions, and always check with your teacher.
- You use the service at your own risk, and we are not liable for decisions made based on its feedback.
What Double Mark is — and isn't
Double Mark uses AI to assess practice answers against published assessment objectives and level descriptors, and returns examiner-style feedback. Marks, grades and comments are an informed estimate to help you improve. They are not official results, are not issued or endorsed by any exam board, and do not predict or guarantee any real exam outcome.
No guarantee of accuracy
We work hard to make the marking useful, but AI can make mistakes. We do not warrant that any mark, grade or piece of feedback is accurate, complete or suitable for any particular purpose. You should treat the output as a study aid and confirm anything important with a qualified teacher.
Limitation of liability
To the fullest extent permitted by law, Double Mark is provided "as is" and we exclude all warranties not expressly stated here. We are not liable for any loss or damage — including lost marks, missed opportunities, or exam outcomes — arising from your use of, or reliance on, the service or its feedback. Nothing in these terms limits liability that cannot be limited by law.
Your account
Keep your login details secure and give accurate information when signing up. You're responsible for activity under your account. New personal accounts include two free markings, after which a subscription is required to continue.
Payments and cancellation
Subscriptions are £5 a month or £50 a year, billed through Stripe. You can cancel any time from your account; access continues until the end of the period you've paid for. Cancelling stops future charges but does not refund a payment already made.
Acceptable use
Use Double Mark for your own study only. Don't misuse it, attempt to disrupt or overload it, resell access, or use it for anything unlawful. We may suspend accounts that abuse the service.
School passwords
School access is for pupils of a school that holds a current licence. Access may be withdrawn if a school's licence ends or the service is misused.
Changes
We may update the service or these terms. If we change the terms, we'll update this page and the "last updated" date. Continuing to use the site means you accept the current terms.
Governing law
These terms are governed by the law of England and Wales, and any disputes are subject to the courts of England and Wales.
Privacy
How we handle your data is explained in our Privacy notice, which forms part of these terms.
