Privacy Policy

Effective date: August 19, 2026

The short version: Mileage does not collect your data. Every measurement you take is processed on your iPhone and never leaves it. We have no servers, no account system, and no analytics or advertising. The only network connection in the app is to our subscription provider, RevenueCat, to manage your purchase.

What we collect

Nothing. Mileage does not collect, store, transmit, or sell any personal information or health data. There is no sign-up, no login, and no user profile.

Measurements stay on your device

To estimate your body age, Mileage reads signals using your iPhone's sensors:

All of this is processed on-device. Your results and history are stored locally on your iPhone only. None of it is uploaded to us or to any third party.

Apple Health (HealthKit)

If you grant permission, Mileage reads selected cardio and recovery metrics from Apple Health, such as VO₂max and resting heart rate, to estimate those two systems. Mileage never writes to Apple Health, and Health data is never transmitted off your device. You can revoke access anytime in the Health app.

Motion sensors

Motion sensors are used only to measure balance during a test. Mileage does not record photos, video, audio, or your location, and does not use your camera.

Subscriptions

Purchases are processed by Apple and managed through RevenueCat, our subscription infrastructure provider. To operate your subscription, RevenueCat processes a randomly generated, anonymous app user identifier and standard purchase/receipt information. This is used solely to deliver the features you paid for. It is not tied to your name or contact details, and it is not used to track you. Apple also handles payment under its own privacy policy.

No tracking or advertising

Mileage contains no advertising SDKs, no third-party analytics, and no cross-app tracking. We do not build profiles about you.

Children

Mileage is not directed to children and does not knowingly collect information from anyone. Because we collect no data at all, this applies to users of every age.

Changes

If this policy changes, we will update the effective date above and post the revised version on this page.
