Saturate

Privacy Policy

Last updated: May 31, 2026

The short version: Saturate doesn't collect, store, or share personal data with the developer. The oxygen reading is calculated on your device from air pressure. If Location is enabled, Apple's geocoding service may process your location to show a nearby city/place name.

Data collected by the developer

None. Saturate has no developer servers, no accounts, no analytics, no advertising, and no third-party SDKs.

Permissions the app uses

  • Location (While Using the App): used to show a nearby city/place name and to estimate air pressure from GPS altitude only when barometer data is unavailable. If Location is enabled, Apple's geocoding service may process your location to show a nearby city/place name. Your location is not sent to the developer.
  • Motion & the barometer: the Apple Watch barometer measures the surrounding air pressure that the oxygen reading is based on. This is processed on your device and is not stored or shared.

Where your data lives

All readings are calculated on your Apple Watch. The most recent reading may be stored locally on the device so a watch-face complication can display it — this data is not uploaded to the developer.

No tracking or advertising

Saturate contains no advertising, no tracking, and no third-party SDKs.

Children's privacy

Saturate does not knowingly collect data from anyone, including children.

Not a medical service

Saturate measures the surrounding air, not your blood oxygen, and does not provide medical advice. It is an informational tool only.
