Privacy Policy

Fusion Habits · effective October 20, 2026 (version 2.0)

Fusion Habits is a habit tracker made by Jean-Baptiste Allaire. This policy explains what happens to your data when you use the app on iOS or Android.

The short version

We do not collect any data. Fusion Habits has no account, no sign-in, no servers, no analytics, no advertising and no tracking. Everything you enter stays on your phone.

What is stored on your device

• Your habits, daily check-ins, streaks and challenge progress.
• Your profile (first name, goals) and your settings, such as reminder times.
• Photos you choose to attach: a profile picture and optional "photo proof" pictures.

This data is saved only in the app's private storage on your device. It is never sent to us or to anyone else.

Camera and photo library

The app asks for camera access only when you turn on photo proof for a habit, and for photo library access only when you pick a profile picture. Photos stay on your device.

Notifications

Daily reminders are local notifications scheduled on your device. No notification service or server is involved.

Deleting your data

Open Profile → Delete all my data to erase everything immediately, or uninstall the app, which removes all of its data from your device.

Children

Because the app collects no personal data, it does not collect data from children.

Changes

If a future version adds an optional online feature, this policy will be updated before that version is released, and the feature will ask for your consent.
