Privacy policy
Last updated 8 October 2026
This explains what personal data we collect when you use IB Prep, why we collect it, who helps us process it and the choices you have. We collect as little as we can: you can use most of the site without an account.
Who we are
IB Prep (ibprep.co.uk) is run by Shayaan Jadoon, 11 Linchfield Road, Datchet, Slough, SL3 9NA. You can contact us at support@ibprep.co.uk. We are the controller of your personal data under UK data protection law (the UK GDPR and the Data Protection Act 2018).
What we collect, and why
- Your email address, if you create an account, so you can sign in with an emailed link and keep your progress across devices. Legal basis: providing the service you asked for (contract).
- Your answers to set-up questions: that you're 18 or over, the level you're applying for, target firms, interview date and study time per day. We use these to build your study plan. Legal basis: contract.
- Your progress: which questions you answered and whether you got them right, your flashcard schedule, and the marks from practice interviews. We keep your marks, but not the words of your interview answers. Legal basis: contract.
- Your plan: when your free trial ends, and if you buy a plan, which plan, its status and renewal date. Stripe handles the payment itself. Legal basis: contract, and keeping records the law requires.
- Mentoring requests: your name, email, what you'd like help with, your availability and preferences, so we can match you with a mentor and arrange a session. Legal basis: taking steps at your request before a contract.
- Mistake reports you send about a question, so we can fix it. Legal basis: our legitimate interest in keeping content accurate.
- Technical data: your IP address is used briefly to stop abuse (for example, too many requests a minute), and our hosting provider keeps standard server logs. Legal basis: legitimate interest in keeping the service secure.
Without an account, your progress is saved only in your browser on your device. We don't receive it.
Practice interviews: audio and video
- Video from your camera never leaves your device. It's only there so you can watch yourself back, and it's deleted when you move on.
- Spoken answers are turned into text. Live captions use your browser's own speech recognition (in Chrome, this is provided by Google). We may also send the recording to OpenAI to turn it into text; it's processed and not kept by us.
- Your answer text is sent to OpenAI to be marked and to generate follow-up questions, then shown to you. We don't store it; only the marks are saved.
We ask for your consent before your microphone or camera is used, and you can type your answers instead.
Who processes your data for us
We use these providers, under contracts that require them to protect your data:
- Supabase: our database and sign-in system (stores your account and progress).
- Vercel: hosts the website.
- OpenAI: marks interview answers, writes follow-up questions, turns speech into text and reads questions aloud. OpenAI doesn't use data sent through its API to train its models.
- Google: our business email (support@ibprep.co.uk), live captions if you use Chrome, and sign-in if you choose “Continue with Google” (we receive your name and email address from Google, nothing else).
- Stripe: takes payments if you buy a plan or a mentoring session. We never see or store your full card details.
Some of these providers are based in, or process data in, the United States. Where data leaves the UK, it's protected by the UK's approved safeguards, such as the UK International Data Transfer Addendum or the UK–US data bridge.
We never sell your data and we don't show adverts.
How long we keep it
- Your account and progress: until you delete your account.
- Mentoring requests: up to 12 months after your last session or request.
- Mistake reports: kept to improve the content, and no longer linked to you once you delete your account.
- Payment records: as long as the law requires for tax and accounting (usually six years).
You can delete your account, with all its progress, at any time from your account page.
Cookies and browser storage
We only use cookies that are needed for the site to work: they keep you signed in. We don't use advertising or tracking cookies, so we don't need to ask you to accept them. Your progress is also saved in your browser's local storage so the site works without an account; clearing your browser data removes it.
Age
IB Prep is for people aged 18 and over, and we ask you to confirm this before you create an account or book mentoring.
Your rights
You can ask to see the personal data we hold about you, correct it, delete it, restrict or object to how we use it, or receive a copy to take elsewhere. Email support@ibprep.co.uk and we'll reply within a month.
If you're unhappy with how we've handled your data, please tell us first. You also have the right to complain to the Information Commissioner's Office (ico.org.uk).
Changes
If we change this policy, we'll update the date at the top, and tell you by email if the change is significant.
