WHO WE ARE
Colosse is a supplement tracker (creatine, protein, vitamins) published by Charles Sontag, sole trader, based in Paris, France. Contact: studio.muuy@gmail.com
THE SHORT VERSION
Colosse has no account, no sign-up and no server of its own. What you enter stays on your phone. We cannot see your data, because it never reaches us.
WHAT THE APP STORES, AND WHERE
On your device only:
· your body weight and your stated goal (maintenance, bulking, cutting)
· your daily intake: protein, creatine, supplements
· your progress: days held, level, coins, what you have collected
· the progress photos you choose to take
None of it is tied to your identity. No name, no email address, no account.
PROGRESS PHOTOS
Taking photos is optional, and the app works fully without a single one. When you add one, the file is copied into Colosse's own folder on your device. It is never uploaded, never transmitted, never shared: the app contains no network call anywhere in its photo code.
You can erase all your photos at any time from Settings, in two taps, without touching the rest of your progress. They are removed with the app when you uninstall it.
The app asks for camera and photo library permission only at the moment you take your first photo, never before.
REMINDERS
If you turn reminders on, up to three daily notifications are scheduled locally, by your own device. There is no push server. No message is ever sent from us to you.
PAYMENTS
Subscriptions are handled by Apple and by RevenueCat, our subscription provider. We never see your payment details. RevenueCat receives an anonymous technical identifier whose only purpose is to tell the app whether your subscription is active. Their own privacy policies apply to what they process:
· apple.com/legal/privacy
· revenuecat.com/privacy
WHAT WE DO NOT DO
No advertising. No analytics. No tracking. No profiling. We do not sell, rent or share your data with anyone for commercial or advertising purposes.
CHILDREN
Colosse is not directed at children under 13 and does not knowingly hold their data.
YOUR RIGHTS (GDPR)
Because your data never leaves your device, you hold it directly. You can see it, change it and erase it from the app's Settings, and uninstalling Colosse deletes all of it. If you have a question about any of this, write to studio.muuy@gmail.com.
CHANGES TO THIS POLICY
If this policy changes, the new version is published on this page with a new date.
