Lumo Open the app

Privacy policy

Last updated: July 2026

Lumo is a learning app for children, managed by their parents. We collect as little as possible, we never show ads, and we never sell data. This page explains, in plain words, what we store and why.

The short version

Using Lumo without an account

Lumo works fully offline. Without a sign-in, all profiles and progress are stored only on your device and are never sent to us. Deleting the app (or a profile) removes them.

If a parent signs in

Accounts are for grown-ups only — children never sign in and never have accounts. A parent can sign in with Google to back up progress and use the same account on more than one device. We then store:

That is the whole list. We do not collect birth dates, photos, locations, contacts, or anything from outside the app.

Children and consent

Child profiles are created and managed by a parent or guardian, inside a grown-up-gated area of the app. The parent decides whether any data leaves the device (by choosing to sign in or not), and can remove it at any time.

Where data is stored

Synced data is stored on our own server in France, in the European Union, hosted with OVH. It is sent over an encrypted connection (HTTPS). On your device, sign-in tokens are kept in the phone's secure storage.

Server logs

Like almost every web service, our server keeps short technical access logs (your IP address, the time, and the page requested) to keep the service secure and diagnose problems. These logs are rotated automatically and only a limited amount is kept — older entries are deleted as new ones arrive, typically within days to a few weeks. They are not used for tracking or profiling.

What we never do

Deleting your data

You are in control, from inside the app (Grown-up zone):

You can also just sign out and never sync again — or use the app fully offline from the start.

Your rights (UK GDPR)

You have the right to access, correct, export or erase the personal data we hold about you and your children, and the right to complain to the ICO (ico.org.uk). For anything this app's built-in tools don't cover, contact us and we will help.
