How Juno Labs Limited uses personal data in JunoClass.

Last updated 26 September 2026.

1. Who we are

Juno Labs Limited (company number 17347135, registered in England and Wales) is the organisation that provides JunoClass. The registered office is 281 Lidgett Lane, Leeds, England, LS17 6PD.

Email hello@junoclass.com if you have a privacy question or want to use your data rights.

2. Controller and processor

When a school or teacher uses JunoClass for a class, that school (or the teacher acting for the school) is usually the controller of pupil data. Juno Labs Limited is the processor. A school can ask us for a data processing agreement. See school data.

Juno Labs Limited is the controller of teacher account data, and of a student’s account when they sign up themselves (including if they buy their own seat).

3. Data we collect

Depending on how the service is used, we may process:

  • name, email address, and optional school name
  • role (teacher or student) and sign-in method
  • class membership, class names, and class codes
  • teacher invitations and collaborator details
  • questions, topics and other content a teacher writes
  • set work, completion, and attempt results (including answers and timestamps)
  • seat status, assigned email, purchase records and payment references
  • technical logs needed to run and secure the service

We do not ask for dates of birth, home addresses, or special category data as part of a normal account.

4. Why we use it

We use this data to:

  • create and keep accounts
  • run classes, set work and revision
  • show teachers class and student results
  • sell, assign and fulfil seats
  • keep the service secure and fix faults
  • answer support requests and meet the law

Where we are the controller, we rely on one or more of: the contract to provide the service, our legitimate interests in running a secure education product, legal obligations, and (for optional school name) the information you choose to give us. Where we are the processor, we follow the school’s instructions.

5. Who we share it with

We use other companies to run the product:

  • Google Firebase Authentication, for sign-in (including Google and Microsoft login)
  • Microsoft, if you choose to sign in with a Microsoft account
  • Supabase, to store application data
  • Stripe, to take card payments for seats

Teachers see students in the classes they own or collaborate on. Students see their own work. We do not sell personal data. We may disclose data if the law requires it.

6. International transfers

Some of the companies above may process data outside the UK. Where that happens we rely on an appropriate safeguard, such as the UK International Data Transfer Addendum or an adequacy decision.

7. How long we keep it

We keep account, class and attempt data while the account is active and the service needs it. Payment records are kept for as long as tax and accounting rules require. If you ask us to delete an account, we remove or anonymise personal data unless we must keep it.

A school that is the controller can ask us to delete pupil records for its classes. We will ask for enough detail to verify the request.

8. Your rights

Under UK GDPR you can ask for access, correction, deletion, restriction, or a copy of data you provided, and you can object to some processing. Email hello@junoclass.com. You can also complain to the Information Commissioner’s Office at ico.org.uk.

9. Children

JunoClass is meant for secondary school use. Students under 13 should only use it through a school or with a parent or guardian. We do not use children’s data for marketing.

10. Cookies

We use a small number of cookies and similar tools to keep you signed in and to take payment. See the cookie policy.
