Privacy Policy — Doza

Last updated: July 22, 2026

In short: Doza works 100 % on-device. Your health data (doses, weight, height, settings) stays on your iPhone: no account, no ads and no advertising trackers. The only technical exception is the anonymous validation of your subscription (see section 5).

1. Who is responsible

The “Doza” application is published by Infini Consulting (trading as “Infini Apps”), a company registered in France (RCS Paris 103 122 420), 47 rue Vivienne, 75002 Paris. For any question about your data, contact: contact@infini-apps.com.

2. What data is processed

All of the data below is entered by you and stored only on your device:

Your doses (molecule, amount, date, injection site);
Your weight and, if you provide it, your height (for BMI calculation);
Your preferences (units, default treatment, dose frequency, reminders).

3. Health data (Apple HealthKit)

If — and only if — you allow it, the app accesses Apple Health (HealthKit) to:

read your weight and heart rate in order to display them in the app;
write the weights you enter, so they sync with Apple Health.

This health data never leaves your device, is never used for advertising or marketing, and is never shared with third parties. You can revoke this access at any time in iOS Settings → Privacy → Health → Doza.

4. Notifications

If you enable them, dose reminders are local notifications, scheduled and triggered on your device only — no push notification server is involved.

5. In-app purchases

“Doza Premium” subscriptions are offered through Apple's App Store; we have no access to any payment information. To verify your subscription status (trial, active, expired), the app relies on our provider RevenueCat, Inc. (United States), which only receives your purchase history and an anonymous identifier generated by the app — never your health data, never your identity. This information is used solely to unlock the app; it is neither linked to your identity, nor sold, nor used for advertising purposes.

6. What we do not do

No collection or transmission of your health data to any server;
No user account, no sign-up;
No advertising, no analytics, no advertising trackers;
No selling of your data, and no sharing for advertising purposes.

7. Retention and deletion

Your data stays on your device for as long as the app is installed. To delete everything, uninstall the app. Data written to Apple Health is managed directly in the Apple Health app.

8. Your rights (GDPR)

Since your health data is stored locally and never transmitted, you retain full control over it at all times. In accordance with the GDPR, you have the right to access, rectify and erase your data, which you exercise directly within the app (and via Apple Health for HealthKit data). For any question, write to contact@infini-apps.com.

9. Children

The app is not intended for people under 16.

10. Medical disclaimer

Doza is a personal tracking tool. It does not provide medical advice, and the displayed curve is an indicative estimate, not an actual concentration measurement. Always consult a healthcare professional for any decision regarding your treatment.

This policy may be updated; the date at the top of the page indicates the latest revision.
