Privacy Policy

Last updated: 6 October 2026

Lumo is a habit tracker. This policy explains what data the app stores, why, and the choices you have. In short: we keep only what's needed to run your account and sync your habits, we don't sell anything, and we don't show ads.

What we store

Account: your email address and, if you choose, a display name and profile photo. If you sign in with Google, we receive your name, email and profile picture from Google.
Your habits: the habits you create (name, icon, color, schedule, goal, reminder time) and your daily progress.
Settings: app preferences such as language, theme and reminder settings, so they follow you to other devices.

We do not collect location, contacts, health data, advertising identifiers or analytics about how you use the app.

How we use it

To sign you in and keep you signed in.
To store and sync your habits, progress and settings across your devices.
To send you account emails you ask for, such as sign-up confirmation and password reset.

Reminders are scheduled on your device by the app; they are not sent from our servers.

Where it's stored

Data is stored with Supabase, our database and authentication provider. Access is restricted so each account can only read and change its own data. A copy of your data is also kept on your device so the app works offline.

Sharing

We don't sell or rent your data and don't share it with advertisers. It is processed only by the service providers needed to run Lumo (Supabase for storage and authentication, and Google if you choose Google sign-in).

Your choices

Edit: change your name, photo, habits and settings in the app at any time.
Delete: use Profile → Delete account in the app. This permanently deletes your account, profile photo, habits and history.
Sign out: sign out on this device, or sign out of all devices, from the Profile tab.

Children

Lumo is not directed to children under 13, and we don't knowingly collect data from them.

Changes

If this policy changes, we'll update the date above and, for significant changes, mention it in the app or on this site.
