Privacy Policy — Crew Recovery

Crew Recovery is a personal tool for long-haul pilots providing sleep, light and rest advice around rotations. It is built on one principle: all your data stays on your own device.

Data the app uses

Roster: the app reads events from the calendar you select yourself. The roster is processed on-device only, to recognise rotations, report times and rest periods.

Health data (Apple Health): sleep, resting heart rate, HRV, wrist temperature, respiratory rate, blood oxygen, daylight minutes and workouts — read solely to compute your recovery and alertness. Logged caffeine and alcohol may be written to Apple Health.

Health data (Android — Health Connect): on Android the app reads sleep, heart rate during sleep (for the sleeping pulse), resting heart rate, HRV, respiratory rate and blood oxygen from Health Connect; no workouts — solely to compute your recovery and alertness on-device. The app writes nothing to Health Connect.

Barometer: your phone's pressure sensor is used on-device to detect whether you are airborne (cabin pressure). Nothing is stored or transmitted.

Manual input: fatigue scores (Samn-Perelli), intake, naps, illness, pickup times, bunk-rest planning and any private trips you enter yourself.

What happens to your data

Everything stays local. The app has no servers, no accounts and no analytics. No data is transmitted, sold or shared — with anyone.

Health data is never used for advertising or marketing and never disclosed to third parties. Use of information received from Health Connect adheres to Google's Health Connect permissions policy, including the Limited Use requirements: read-only, for the features above, nothing else.

iPhone–Apple Watch communication runs directly between your own devices over Apple's encrypted WatchConnectivity channel.

The optional data export creates a file that you keep or share yourself; the app never sends anything on its own.

Deleting the app removes all app data. Health data in Apple Health or Health Connect remains under your own control via the respective app.

What the app is not

Crew Recovery provides no medical advice and is not a fitness-for-duty instrument. Your airline's official procedures and regulations always prevail.
