Privacy Policy

In short: your measurements and doses (injections, weight, height, how you feel) are stored on your iPhone and are never sent to us. Two technical exceptions, described below: subscription validation (section 5) and usage statistics that contain none of your measurements (section 6). No account, no ads, no advertising trackers.

One more thing: anything you share yourself (such as the progress card) obviously leaves the device; and if you have enabled iCloud backup or Apple Health sync, Apple keeps an encrypted copy of your data, under your control.

1. Who is responsible for your data

The "Doza" app is published by Infini Consulting (trading as "Infini Apps"), a company registered with the Paris Trade and Companies Register (RCS) under number 103 122 420 (full details on the legal notice page). For any questions about your data, contact: contact@infini-apps.com.

2. What data is processed

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

Your injections (medication, dose, date, injection site) and how you feel;
Your weight and, if you enter it, your height (for the BMI calculation);
Your preferences (units, default treatment, frequency, reminders).

If you share something yourself (for example the progress card), it leaves the device through your own action, to the app you choose.

3. Health data (Apple HealthKit)

If — and only if — you allow it, the app accesses Apple's Health app (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 the Health app.

This health data is never sent to us, is never used for advertising or marketing, and is never sold. If you have enabled iCloud sync for the Health app, Apple keeps an encrypted copy — that is your Apple setting, not ours. You can revoke Doza's access at any time in iOS Settings → Privacy & Security → Health → Doza.

4. Notifications

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

5. In-app purchases

"Doza Premium" subscriptions are offered through Apple's App Store; we never have access to any payment details. To check your subscription status (trial, active, expired), the app relies on our provider RevenueCat, Inc. (United States). It receives your purchase history and a technical identifier specific to your installation — never your health data, never your identity. This transfer to the United States is covered by the European Commission's standard contractual clauses. Purchase events are also counted in our usage statistics (see section 6).

6. Usage statistics (TelemetryDeck)

To understand how the app is used and improve it, we count usage events: a screen viewed, a dose logged, a weight entry added — never the dose, weight, medication or symptom itself. Each event travels with technical information: app version, device model and iOS version, language and region, display preferences, and usage counters (number of sessions, days of use).

The only exception to the "never the value" rule: purchase events indicate the plan chosen, the store country, the currency and an approximate amount converted to US dollars. No payment details are ever included.

These statistics are processed by TelemetryDeck GmbH (Augsburg, Germany) and stored in the European Union. They travel with a hashed technical identifier specific to your installation: neither we nor TelemetryDeck can trace it back to you. No IP address is kept, no advertising identifier, no cross-app tracking.

They are kept for as long as needed for analysis, then deleted. This is simple audience measurement — which is why you don't see a consent banner.

7. What we do not do

None of your measurements (dose, medication, weight, symptom) is sent to a server;
No user account, no sign-up;
No ads, no advertising trackers;
No selling of your data, and no sharing for advertising purposes;
Usage statistics are not linked to any identity (section 6).

8. 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 the Health app is managed directly in Apple's Health app. If your device's iCloud backup is enabled, the app's backup is included in it, encrypted.

9. Your rights (GDPR)

Your data is on your device: you view, edit and delete it directly in the app (and in the Health app for HealthKit data). Usage statistics are not linked to anyone — so we cannot find "your" events to hand them over or erase them; sending stops when you uninstall the app.

Need to reach us? contact@infini-apps.com. You may also lodge a complaint with the French data protection authority, the CNIL, or with your local supervisory authority.

10. Children

The app is not intended for anyone under 16.

11. Medical disclaimer

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

12. Changes

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