Privacy
Your child's data, in plain English
Nimbo Study is used by children, so this page is written to the standard of the UK ICO Children's Code: minimal data, no tracking, and nothing collected that the product does not visibly need.
The short version
We store your email address, a nickname for your child and their year group, and the practice questions they answer. We run no analytics trackers, set no third-party cookies (which is why there is no cookie banner), and never sell or share data. You can delete everything, permanently, from the parent view at any time.
What we collect
- From you: the email address of the Google account you sign in with — we never see your password. If you use Write to us, we also keep your message and the name and version of your browser (to help us fix what you report), until you delete your account.
- About your child: the nickname and year group you enter — a nickname is all we ask for, it need not be their real name — and their practice record — which questions they answered, their attempts, and which hints were shown. We deliberately do not ask for gender, date of birth, school, or photographs.
- Reports: when a child taps Something looks wrong, we keep which question and which of four fixed reasons — never anything they type. It goes when their profile is deleted.
- Payments: handled entirely by Stripe on Stripe's pages. Card details never touch our servers.
- Referral codes: your own sharing code, and the code you joined with, if any, so the parent who shared it can be given their free month. They see only how many families joined and paid, never who. It goes when your account is deleted.
What we do with it
The practice record exists to choose the next question well and to show you honest evidence of what your child has worked on. It is not used for advertising, profiling beyond the practice itself, or comparison with other children — the product has no code path for comparative claims.
Once a week we e-mail you a short note about what your child practised, with the same counts the parent view shows. You can turn it off there. If an AI model words the note, it receives counts and topic names only — never your child's nickname, your e-mail address or anything else about you — and the note says so.
What we never do
- No advertising or analytics trackers, on any page — child or parent.
- No third-party cookies. Our single cookie keeps you signed in.
- No selling, renting, or sharing of personal data.
- No marketing to children, and no commercial content on any page a child uses.
Where it lives, and for how long
Data is stored in our own database in the UK/EU and backed up daily. It stays until you delete it: removing a child profile erases their entire practice record, and deleting your account erases everything from our database, immediately and permanently — both from the parent view, no email required. Our nightly backups roll over, so deleted data is gone from them within 30 days. Stripe keeps its own record of past payments (invoices), as UK tax law requires.
Your rights
Under UK GDPR you can access, correct, or erase your family's data. Deletion is built into the product; for anything else, or any question, use Write to us in the parent view or write to support@nimbostudy.co.uk and a human will answer.
If you are unhappy
Tell us first: choose My data or privacy in Write to us, or e-mail us. We confirm we have your complaint within 30 days (the form usually confirms it by e-mail straight away), then tell you what we found. You can also complain to the Information Commissioner's Office (ico.org.uk).
