Terms of Service

These terms are between you and Tristan Pagden, trading as cookie and Cookie Tutoring, in the United Kingdom (“cookie”, “we”). Our contact details are on the contact page. If you are under 18 and somebody else pays for Pro on your behalf, that person is the one buying it and these terms apply to them for the purchase.

By creating an account or using cookie, you agree to these terms. If you don't agree, please don't use the service. See our Privacy Policy for how we handle your data.

cookie generates exam-style practice questions from source material you provide (your own notes, a topic list, a worksheet from class), marks your answers using AI, and schedules what to review next using spaced repetition. Question generation and marking are performed by a third-party AI model (OpenAI today; Anthropic only if we ever switch, and we would say so first). They're generally accurate but can make mistakes, the same as any AI system. Treat cookie as a study aid, not an official examiner or a guarantee of your real exam result.

• You must provide accurate information and keep your login details secure.
• One account per person. You're responsible for activity on your account.
• A username is required and must be unique, and we may reject offensive or impersonating usernames.
• You must be 13 or over to create your own account; from 13 you do not need a parent or guardian to sign up. A parent or guardian sets up an account for a younger child through Cookie Tutoring (see “Children” in our Privacy Policy). On Cookie Tutoring, lessons for a student under 16 are booked and paid for by a parent, guardian or sponsor, who must be 18 or over; from 16 a student may book their own.

• cookie offers a free plan with limited monthly credits, and a paid Pro plan with a higher allowance. Credits are consumed by actions that use AI, like generating and marking questions.
• Pro subscriptions are billed through Stripe at the price shown when you subscribe, either monthly or yearly, and renew automatically at the end of each month or year until cancelled. A yearly subscription still gives you your credits a month at a time. If we change the price we tell you by email at least 30 days before it applies to you, and you can cancel before it does.
• Before you pay again we remind you by email: 7 days before a free period ends, 14 days before each yearly renewal, and on a monthly plan at least once every six months, 7 days before the payment. Each reminder says what you will pay, when, and how to cancel.
• You can cancel at any time, online, with the Cancel Pro button on your account page or in the billing portal. It takes one click and you do not need to give a reason. You'll keep Pro access until the end of your current billing period, and we confirm the cancellation by email.
• Your legal right to cancel. Because you buy at a distance, you have 14 days from subscribing to change your mind. Pro starts straight away at your request; if you cancel within those 14 days with Cancel and get a refund on your account page, we refund the part of the month (or, for a yearly subscription, the year) you have not used, straight away and in any case within 14 days. Most of what Pro gives you is its credits, which arrive at the start, so we count what you have used in two ways, by days (the day you cancel counts as used) and by the share of the period's Pro credits you have spent, and use whichever is larger. The Pro credits you had not used are removed when we refund; credits you bought separately are kept. You have the same 14 days again after each yearly renewal, and after the first payment that follows a free period, and we email you when each of those opens. After that, cancelling stops the next payment and you keep Pro until the period ends. You can also cancel by sending us a plain email saying you wish to, or the model cancellation form in the Regulations.
• Credits you buy on top are added to your account straight away at your request, and you accept that once they are you lose the right to cancel that purchase. Bought credits do not roll over: whatever is unused is wiped at your next monthly reset, which we tell you before you buy.
• Beyond that, fees are non-refundable except where the law requires it or, at our discretion, for a genuine billing error.

• Any account can share a referral link. When somebody makes a new account with it and later takes out Pro, the person who shared it gets 5,000 bonus credits and the new account gets 2,000.
• Both are added once the new account's first payment is 14 days old, has not been refunded, and the subscription is still active. A free trial or Pro given through Cookie Tutoring is not a payment.
• A referral counts only for a new account belonging to a different person, made in the last 30 days, on an email address that has not had an account in the last month. One referral per account.
• Up to 5 referrals a calendar month earn bonus credits for the person who shared the link. Any more are paid in the following months, in order.
• Bonus credits last 12 months from when they are added, are not wiped at the monthly reset, and are used after your monthly credits. On the free plan they can take you past the free daily limit, up to the Pro daily limit. They have no cash value and cannot be transferred.
• If we find referrals being made in bad faith (for example, accounts made to refer yourself), we may cancel the referral and remove the bonus credits it earned.

You agree not to:

• Upload content you don't have the right to use (e.g. copyrighted material you're not licensed to reproduce).
• Use cookie to generate or share unlawful, harassing, or hateful content.
• Attempt to circumvent credit limits, rate limits, or security controls.
• Use automated tools to scrape or abuse the service outside its intended use.
• Impersonate another person or misuse the username system.

We may suspend or terminate accounts that violate these terms, remove content that violates them (including public decks or reviews), or, for serious or repeated abuse, do so without prior notice.

Some things are never allowed on cookie, whether in a deck you make public, in its name or description, in a review, in a username, or in anything you send a tutor or a student:

• Anything illegal. That includes anything sexual involving a child, threats, harassment, content that stirs up hatred, fraud, and content from a terrorist or proscribed organisation.
• Pornography or any sexual content.
• Anything that encourages, promotes or gives instructions for suicide, self-harm, or an eating disorder.
• Bullying, and content that abuses or incites hatred against people because of their race, religion, sex, sexual orientation, disability or gender reassignment.
• Content that encourages serious violence, or shows real or realistic serious violence or injury.
• Anything that encourages a dangerous stunt or challenge, or taking a harmful substance.
• Content that shames someone's body or appearance, or that promotes hopelessness and despair.
• Sending anyone a sexual image they did not ask for.

Most people who use cookie are at school. We treat all of this as applying as if a child will see it, because one probably will.

Most of cookie is private: your decks, your answers and your marks are yours, and nobody else sees them unless you make a deck public or accept a tutor. Where other people can see what you post, this is what protects you from illegal content of every kind, including terrorism and anything sexual involving a child, and from content that is harmful to children:

• Nothing is public unless you choose. A deck is private until you publish it, shown without your name unless you attach your username, and you can make it private again at any time.
• Only people who have actually used a deck can review it. You have to import a deck before you can rate or review it, and you get one review per deck.
• A tutor sees your work only if you accept them. A tutor can invite you, but nothing is shared until you say yes, and you can stop it.
• Every public deck and every review has a Report button. When you report something, a person looks at it and you get an answer within 5 working days.
• We take down what should not be there. If something is illegal or breaks these terms we unpublish the deck or remove the review, straight away for anything sexual involving a child, anything from a terrorist organisation, or anything else illegal, and we keep a note of what we did and why. Removing it from cookie also removes it from search engines, because we tell them.
• We may also act against the account. Where somebody breaks these rules we can put their account on hold, which stops them publishing decks, writing reviews or inviting students. They can still sign in and study, nothing of theirs is deleted, and we tell them why and how to object.

We do not run any automatic scanning of what you publish or write on cookie for the purpose of finding illegal or harmful content. Nothing is filtered, hidden or removed by software. When something is removed, a person decided.

cookie does use AI to generate questions from your material and to mark your answers. That is what the product does, not a safety check, and it is described under “What cookie is” above.

There is a Report button on every public deck and on every review. Press it, tell us what is wrong if you want to, and a person will look. You do not need an account; the button works whether or not you are signed in. If you would rather write to a person, email support@cookie.education or use our contact form.

The person you report is not told who reported them. Reporting something that turns out to be fine is always the right call.

If you are worried about a child, or you are a child and something has upset you, you do not have to work out whether it is our problem first. Childline is 0800 1111 and the NSPCC is 0808 800 5000; both are free and both are independent of us.

This applies to any decision we make: a deck of yours we unpublished, a review we removed, a report of yours we did not act on, anything we did to your account, and a complaint that we are not doing what the Online Safety Act requires of us.

• Email support@cookie.education and say what happened and what you think should change. There is no form and no deadline.
• A person reads it, the same person who made the decision, because there is currently one, and we would rather say that than imply a panel that does not exist. You get a reply within 5 working days.
• If we were wrong, we undo it as far as we can: a deck goes back to public, a review goes back up, and anything about money is put right rather than credited.
• Nothing on this page removes any right you already have.

The person accountable for how cookie meets its online safety duties, and for how reports and complaints are handled, is Tristan Pagden, the founder. That address reaches him.

You retain ownership of the source material you upload and the answers you write. By uploading content, you grant cookie a licence to store it, copy and reformat it, send it to our AI providers, show it back to you and keep it in our backups, solely to provide the service to you. That licence ends when you delete the content or your account, apart from backups that roll over within a month. You're responsible for making sure you have the right to upload and use any material you submit, and we ask you to confirm that each time you create a deck. Exam boards license their past papers, mark schemes and specifications to schools and do not permit them to be uploaded to apps like this one; your own notes on them are fine.

Separately and narrowly: when you correct something our AI produced (challenging a mark, moving a question to a better topic, telling us a category is wrong), you grant us a licence to keep that correction, and the AI output it corrects, and to use them to improve our AI. That licence covers the correction itself and nothing else. Your uploaded source material is expressly outside it.

You can withdraw that second licence at any time by turning off Helping us improve our AI in your account settings, which stops us keeping any further corrections. See our Privacy Policy for what is kept and for how the setting defaults for under-18s.

If you choose to make a deck public, its questions and any source text you pasted become visible to anyone who visits the site, and a person who imports the deck receives a copy of its questions and its source files in their own account. If you share notes, the copy of their text you shared becomes visible to anyone who visits the site, and a person who adds them receives a copy in their own notes. Anyone can also download shared notes without adding them, and anyone signed in can download a shared flashcard deck as an Anki file. Only publish or share material you have the right to share. By default, public decks and shared notes are shown without attribution to you. You can make a deck private again, or stop sharing notes, at any time, which removes it from public browsing (copies other people have already made or downloaded are not affected).

The questions, mark schemes, marks, comments and worked solutions cookie produces are generated by an AI model. You may use them for your own study and, if you are a tutor, for your students. We own them for copyright purposes and license them to you for that; we make no promise that they are unique, complete, accurate, or free of other people's rights, and you use them as a study aid on that basis.

If you use cookie's tutor features (as a tutor or a student), your tutor may be able to see your practice activity, scores, and assigned work within decks they've shared with you. A tutor gains that access only once you accept them, by accepting their invite on cookie, or by asking them for a lesson on Cookie Tutoring and them accepting. Anyone can choose “I'm a tutor” when they sign up, but no tutor is listed in our tutor directory until we have verified them, including a DBS check. A tutor you have accepted can correct a mark our AI gave you; their mark then stands as yours, and the answer says so.

cookie is provided “as is.” AI-generated questions and marking may occasionally be inaccurate, incomplete, or not perfectly aligned with a specific exam board's real mark scheme. Always use your own judgement, and don't treat a cookie score as a guaranteed predictor of your real exam result. We don't guarantee the service will be uninterrupted or error-free.

Nothing here limits our liability for death or personal injury caused by our negligence, for fraud, for a breach of the rights the Consumer Rights Act 2015 gives you, or for anything else the law does not allow us to limit. Beyond that, we are not liable for indirect or consequential loss arising from your use of the service, including exam outcomes, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim arose, and never to less than the price you paid for the thing the claim is about. Nothing in these terms affects your statutory rights.

If something has gone wrong, tell us through the contact page or by email and say what you think should change. A person reads it and you get a written answer within 5 working days. We do not belong to an alternative dispute resolution scheme; if you are unhappy with our final answer you can go to the courts, and if you paid by card you keep every right you have with your card issuer. A complaint about your personal data has its own route, described in our Privacy Policy.

If a public deck or a review infringes your copyright, or says something about you that is untrue and damaging, you do not need an account to tell us: the content-notice form says what to include and what happens next. We acknowledge a complete notice within 2 working days.

We may update these terms where the law changes, where cookie changes, or to fix something that was unclear. If we make material changes, we'll update the date at the top of this page and tell you by email before they take effect, and you can close your account if you do not agree.

These terms are governed by the laws of England and Wales. You can bring a claim in the courts of England and Wales; if you live in Scotland or Northern Ireland you can also bring one in your own courts.

If you have questions about these terms, email support@cookie.education or use our contact form.
