Revzy (including Revzy Business) is a trading name of JMM Web Apps Ltd, a company registered in England and Wales (company number 17544480). Registered office: 13 Vansittart Estate, Windsor, SL4 1SE. JMM Web Apps Ltd is the "controller" of your data, which means it decides how your data is used and is responsible for looking after it. JMM Web Apps Ltd is registered with the Information Commissioner's Office (ICO), registration number ZC285994. Contact: hello@revzy.co.uk, or write to us at the registered office. Revzy is for students in the UK.
Revzy is for students aged 13 and over. If you are under 13, please don't sign up. We have kept Revzy private by default: no adverts, no tracking cookies, no public profiles, and no way for other users to see or contact you.
We do not collect your school, date of birth, address or phone number.
When you send an answer for marking, the question and your answer are sent to Anthropic, our AI provider, to produce the mark and feedback. Your name and email are not sent. Anthropic does not use them to train its models. We keep your answer with its mark and feedback so you can look back at it under Marked. Only you can see it. It is never included in parent emails.
AI marking is a revision aid. It does not make any decision about you, and marks are indicative, not a prediction of your exam result.
If you add a parent or carer, we send them one email asking them to confirm. Only after they confirm do they get a short weekly summary: questions answered, accuracy by topic, topics to work on, your streak and any mock result. Never your written answers. You can remove them in Account, and they can unsubscribe from any email.
Live view (Exam Season Pass). If you choose, you can send a confirmed parent or carer a private link to a live page. It shows the same things as the weekly email, plus your readiness score for each paper, its trend, and your topic map. Never your written answers or feedback. Only someone with the link can open it, and it is never listed by search engines. It stops working when you turn it off, send a new link, remove them, or your pass ends.
Half-term report (Exam Season Pass). At each school half term, a confirmed parent or carer gets a one-page PDF by email: your readiness for each paper and its trend, your topic map, and the topics you have ticked as covered. Never your written answers. Removing them, or them unsubscribing, stops it.
If you choose to share a result card, it shows your first name, score, estimated grade and your invite link. Nothing is shared unless you share it.
Topic videos on YouTube. Topic videos that are on the Revzy channel on YouTube play from there, using YouTube's privacy-enhanced mode. Nothing loads from YouTube until you press play. When you do, YouTube (Google) receives your IP address and the video you watch, under Google's own privacy policy. Revzy doesn't send YouTube your name, email or anything else about you.
Snapchat and WhatsApp. If you tap Snapchat or WhatsApp in the share sheet, Revzy opens that app with your invite link, and your score only if you switch it on. Revzy never gets your contacts, messages or anything else from those apps, and what you send there is covered by that app's own privacy policy. When you open the share sheet, your browser loads Snapchat's share button from Snap Inc., which shares your IP address with Snap. It isn't loaded anywhere else in Revzy.
We use these companies to run Revzy. They only use your data to provide their service to us.
Where data goes to the United States, the transfer is protected by the UK–US data bridge or by the UK International Data Transfer Addendum.
Revzy has accounts on social media apps. We schedule our posts with Blotato, a publishing tool, which can also show us comments and messages sent to those accounts. If you comment on or message us there, we see your username and what you wrote, and we use it only to reply. Nothing from social media is added to your Revzy account. Each app's own privacy policy covers what you post there.
You can ask to see a copy of your data, correct it, delete it, or stop any emails, by emailing hello@revzy.co.uk. We reply within one month. If you are not happy with how we handle your data, you can complain to the Information Commissioner's Office at ico.org.uk.
We only use storage that Revzy needs to work: your sign-in session, your display settings (theme, text size, font), a friend's invite link or founding code until you finish signing in, and progress through drills and mocks on your device. No advertising or analytics cookies, so there is no cookie banner.
Your data is only reachable through the app when you are signed in, and each student can only see their own. Our server keys are kept out of the website code.
If we change this notice in a way that matters, we will update this page and tell you in the app. On 27 October 2026 we updated it because Revzy is now run by JMM Web Apps Ltd. Nothing about what we collect or how we use it has changed.
