This covers Cookie Tutoring at tutoring.cookie.education. The cookie study app has its own policy. The two share one account system, so your name and email are the same across both, but everything below is specific to tutoring.
Cookie Tutoring is run from the United Kingdom by Tristan Pagden, trading as cookie and Cookie Tutoring, the same person and business that runs cookie. We are the data controller for everything described here. Our address for correspondence is 4th Floor, Silverstream House, 45 Fitzroy Street, London W1T 6EB, United Kingdom. Contact us at support@cookie.education, or through our contact page.
Our lawful bases are: performance of a contract for the person who holds the account and books the lessons; legitimate interests for a student whose lessons are booked by a parent or guardian, because a contract with the parent does not cover the child (we have weighed that interest against the child's, and the child's comes first); the recognised legitimate interest in safeguarding (Article 6(1)(ea) of the UK GDPR) for checking messages for contact details and reading them when there is a concern; legal obligation for financial records and for checking a UK tutor's right to work; for a tutor's application, the steps needed before we can agree to list them, together with our legitimate interest in knowing that the adults who teach children are who they say they are and are safe to do so; and legitimate interests for fraud prevention and keeping the service working. You can object to any processing we do on legitimate interests.
A tutor's criminal record check is criminal-offence data. We process it under the Data Protection Act 2018, Schedule 1, Part 2, paragraphs 10 (preventing or detecting unlawful acts) and 18 (safeguarding of children), and we keep the appropriate policy document those conditions require.
Nothing here asks for information about a student's health, disability or additional needs, and tutors are asked not to write it down. If a tutor needs to know something like that to teach well, tell them in the lesson.
This is worth being direct about, because it is the part people least expect.
If we ever add lesson recording or transcripts, recordings will be kept for no more than 90 days and then deleted, this page will say how long transcripts are kept before any is made, and none of it will start without explicit consent from everyone in the lesson.
Your tutor keeps a short note about how you learn, so they can plan lessons and so a lesson is not spent going over what you already know. This holds learning information only — what you are working towards, what you find easy and hard, and what helps you learn. Nothing about your home, your health, or anything else about you belongs here.
It has four parts, and no free-text box for anything else:
Alongside it we store what you are studying: the subject, the level, the exam board, and the grade you are working at and aiming for.
Your tutor also asks us to suggest a plan for a lesson, using this, their own notes from recent lessons, and how you are doing on your practice questions on cookie. A plan is their preparation and is not shown to anybody else.
Nothing that happens in a lesson is used to train anything: not the whiteboard, not the messages, and not a recording or transcript if we ever add them. That could only change for people who agree to it separately, asked on its own and never as a condition of having lessons, and never for a lesson with anyone under 18 in it. If we ever ask, we will say so on this page before it starts, not after.
We use your corrections to our AI’s output (telling us a mark was wrong, putting a question in a better topic, correcting something we generated) to make that AI better. We never use your uploaded source material or your notes, we never use anything from a lesson unless you have separately agreed to that, and we never use anything that identifies you. You can turn this off at any time, and turning it off does not reduce the service.
Your source material is never used to train anything, whether you turn the setting above on or off. That is not a default we might change: past papers, textbook scans and specifications belong to the people who wrote them, and your notes are yours.
In practice almost nothing on this site produces one of those corrections today, because the AI features live on cookie. The one that matters is a tutor correcting a mark our AI gave their student, which is a real subject expert saying what the right answer was. That is the single most useful thing anyone can tell us, and it is also just a tutor doing their job.
The setting for this lives in your account on cookie.education, because it is one account across both products.
Primarily in the EU (Supabase, Ireland) and the UK (our video and whiteboard servers, London). Some processors (OpenAI, Vercel, Stripe, Resend) are US-based. Where data goes to the United States it does so under the UK International Data Transfer Addendum to the EU standard contractual clauses, or under the UK Extension to the EU–US Data Privacy Framework where the provider is certified, and we have assessed the risk of those transfers. Supabase's support staff can also reach our database from the United States when they need to keep it running. You can ask us for a copy of the safeguards we rely on.
Your account is shared with cookie, so deleting it deletes both. You can start from your account page, which shows anything still outstanding on this side first (a lesson still booked, earnings not yet transferred) and then hands over to cookie, where the account itself lives. Or email support@cookie.education and we will do it. What we keep afterwards is exactly what the list above says, and nothing else: the financial records the law requires; your messages, any lesson reports and any report about you, with your name detached, for the periods above; and, if you were a tutor, the record that we checked you and what we decided. Lesson documents you brought into a lesson are deleted with your account, unless one was taken down after a report, which is kept as evidence for the report's period; whiteboard snapshots are the shared board from a lesson with somebody else, so they keep their own 365-day window. Everything else goes. We will tell you at the time what has been kept and why.
A child under 13 cannot sign themselves up. They can have an account only when a parent or guardian creates one for them, confirming they hold parental responsibility for that child and agreeing to the terms on their behalf. We record who did that and when; that record is what makes the account lawful, so we keep it for as long as the account exists. The child is never asked to agree to anything, and we never send account email to them. The adult sets their password and can change it or close the account at any time. The child signs in with that email address and password only; we don't allow a Google sign-in to be joined to an account set up this way.
Many students here are under 18, and that shapes the whole service rather than being a footnote. Anyone 13 or over can create their own account without a parent or guardian. Under 16, a parent, guardian or sponsor aged 18 or over agrees to the terms and books and pays for lessons, from an account of their own that is separate from the student's; from 16 a student may arrange and pay for their own, and is still treated as under 18 in everything else here. Tutors are DBS-checked before they can be listed; conversations are retained so a concern can be looked into; and referral rewards are arranged with a parent rather than offered to a child directly.
If you are the student, you are told, inside every conversation, that the adult who looks after your lessons can read it; it is not something that happens behind your back. If you are under 13, the adult who set up your account is the person who agreed to this on your behalf.
A parent or guardian can ask us for a copy of their child's data, or ask us to delete it, on the same terms as anyone else. See Safeguarding for what to do if you are worried about something.
You can ask for a copy of your data, ask us to correct it, ask us to delete it, object to our processing it, ask us to restrict it, or ask for the data you gave us in a form you can take elsewhere. You can download a copy of your data as JSON from your account page at any time; for anything else, email us and we will respond within one month.
You can complain to us about how we handle your data, using the complaint form or by email. We acknowledge a complaint within 30 days and answer it as quickly as we can. If you are not satisfied, you can complain to the UK Information Commissioner's Office at ico.org.uk.
Nothing on this site makes a decision about you by software alone that has a legal or similarly significant effect. Whether a tutor is listed, whether a report is upheld and whether an account is suspended are each decided by a person. Where an AI is involved (a suggested lesson plan, a suggested change to a learning profile, a draft of a lesson report), a named tutor reads it and decides, and nothing it writes about you reaches you or your family until they have. Suggested tutors and the assistant only suggest: you choose whether to contact a tutor, and the assistant changes nothing until you confirm it.
The practice marks and predicted grades a lesson plan draws on come from cookie, where they are produced by an AI and described in cookie's own policy, including how to challenge a mark.
The date at the top says when this last changed. If we start doing something materially different with your data, recording lessons for instance, we will tell you before it starts, not after.
