The short version (for students)
- We keep your name, email and how your revision is going, so the app can work and show your progress.
- If a parent or teacher is linked to your account, they can see your progress too.
- We don't sell your information, and we don't show you adverts based on it.
- If you're under 13, a parent or carer needs to set up your account.
- You can ask us to show you, fix or delete your information at any time. Just get in touch.
Who we are
Lobe Limpet is a small independent service run by Cary Gibbs in the United Kingdom, who is the data controller for the personal information described here. You can contact us at .
What we collect
- Account details: your name, email address, account type (student, parent or teacher), password (stored securely by our sign-in provider; we never see it) and, for teachers, your school's name.
- Revision activity: the packs and topics you use, your quiz answers and scores, time spent, XP, streaks and badges.
- Links between accounts: which students are linked to which parents or teachers, and messages parents send to their students in the app.
- Technical information: basic logs needed to keep the service secure and working, such as sign-in times, failed sign-in attempts (the email address typed and the country the attempt came from), error reports, and how much AI each account uses each day (so we can keep usage fair).
Why we use it
- To run your account and the app's features (our lawful basis: providing the service you asked for).
- To show progress to linked parents and teachers (providing the service, and our legitimate interest in supporting students' learning).
- To keep the service secure and fix problems (legitimate interests).
- To reply when you contact us.
We don't sell personal information, we don't use it for profiling or targeted advertising, and we don't send marketing emails.
Who helps us run the service
- Google Firebase provides sign-in and stores app data, in data centres in London.
- Cloudflare securely passes requests between the app and our AI provider. When you make revision from a web page, it also fetches that page for you; the page's words are passed to the AI and not kept.
- Anthropic provides the AI model that marks short written answers, writes learning notes, and (for Plus accounts) helps create notes, questions and flashcards, including reading photos, files and web pages you choose to build revision from. Only the revision content and answer text are sent, not your name or email. Please don't include personal details (for example a student's name on a worksheet) in what you upload.
- GitHub hosts the website's pages.
Some of these providers may process data outside the UK. Where they do, they use legally recognised safeguards such as the UK International Data Transfer Addendum.
How long we keep it
We keep your information while your account is open. You can delete your account yourself at any time: students from their Profile page, parents and teachers from "Delete my account" at the bottom of the menu. A parent can also delete the account of a student they look after. This deletes the sign-in, personal information and revision data straight away. If you ask us to delete your account instead, we do it within 30 days, except where we must keep something for legal reasons.
Cookies and storage
We only use storage that's needed for the app to work, such as keeping you signed in and remembering your theme. We don't use advertising or tracking cookies. If that changes, we'll ask for your consent first.
Your rights
You have the right to access, correct or delete your personal information, to object to or restrict how we use it, and to receive a copy in a portable format. Parents and carers can make these requests on behalf of younger students. Email us to make a request and we'll respond within one month.
If you're unhappy with how we've handled your information, please tell us first. You can also complain to the Information Commissioner's Office at ico.org.uk.
Changes to this notice
If we make important changes, we'll update the date above and let you know in the app.
