Email hello@peregrinelogbook.com with the Apple ID you want to enroll. You'll get an Apple invitation link — tap it on your iPhone, install TestFlight if you don't already have it, then install PEREGRINE.

Logbook screen → ADD FLIGHT → Import CSV. Two formats are recognised natively: LogTen Pro "Dynamic Export Flights" (tab-delimited) and ecrew "Personal Crew Schedule Report" (comma-delimited). If your provider exports something else, email me a sample file and I'll add a parser.

Yes. Logbook, stats, fitness and off-duty tracking all run against a local SQLite database. Briefings and map tiles need a connection. When you come back online, Firestore sync catches up automatically.

No. Sleep, HRV, and resting heart rate are read locally from HealthKit, used to compute your SAFTE score on-device, and never sent anywhere. See the Privacy Policy for the full breakdown.

Simplified implementation of the Hursh et al. 2004 three-process model (Sleep, Activity, Fatigue, Task Effectiveness). Effectiveness % drops with sleep debt and during your circadian trough, recovers with sleep. Below 77 % the app flags a Dawson-Reid ≈ 0.05 % BAC equivalent. HRV from your watch adds a ±10 pp modulation when available. It's a trend indicator, not a regulatory go/no-go gate.

Settings → PILOT → Delete Account. One tap wipes your cloud record, signs you out, and clears the on-device database. Nothing recoverable.

Codebase is Flutter so an Android build is technically close. It's tracked as a milestone after the iOS beta stabilizes. Email if you'd use it.

Two tiers. GA Free — full logbook, stats, export, no subscription. Airline Pro — briefings, SAFTE, circadian, radiation, night-block, layover strategy. Pricing finalises before public launch; beta users lock in a below-launch rate.
