System F Pilot Logbook is a digital pilot logbook and
GPS flight tracker for aviators. It records every flight
end-to-end: tap Start before you taxi, the phone tracks your
route with background GPS while you fly, and at End Flight the
app fills in your logbook entry for you — aircraft flown, hours
logged, day / night breakdown, landings, and airports visited.
Review the inferred values, confirm, and the flight is in your
permanent aviation logbook.

Backed by pilotlogbook.online, an aviation logbook designed
around real-world regulatory compliance (CASR Part 61 in
Australia, RAAus rules for recreational aviation, and FAA Part 61
for US pilots). Currency deadlines, flight-review tracking,
instructor recency and instrument-proficiency checks are all
computed for you.

What the mobile app does:

• Live GPS flight recording — a foreground service records
your position at 1 Hz for the entire flight. Runs in the
background so you can put the phone in a pocket, switch apps,
or lock the screen. Battery-friendly; a two-hour VFR flight
costs about 5% of a Pixel's charge.

• On-device flight-phase detection — the recorder tags every
moment as parked, taxiing, taking off, airborne, or landing.
Idle head-and-tail is trimmed automatically before upload so
your recorded flight time reflects the actual chock-to-chock.

• Automatic flight-form pre-fill — the server analyses your
GPS track and estimates which of your aircraft you flew (from
ground-speed profile), how many hours to log, which airports
you visited (proximity to elevation), whether the flight was
day, night, or both (solar position), and how many landings
(touch-and-go vs full-stop vs go-around).

• Photos and videos from the flight window — after End Flight,
the app scans your gallery for media captured during the
recording session and offers to attach any of it. Nothing from
the rest of your gallery is ever read.

• The complete logbook — flights, aircraft, engines, airports,
waypoints, aviator profiles, endorsements, medical documents,
currency deadlines, and a CASR-compliant PDF export for
regulatory presentation.

• Nine colour themes — including a high-contrast accessibility
theme and a true-black midnight theme for OLED night use.

• Automatic aviator-profile matching — when someone logs a
flight with you, the system fuzzy-matches on your name,
registered identifiers, and date of birth so that history rolls
in when you claim your profile.

Privacy — your data is yours.

- Background GPS runs only during a flight-recording session;
never before Start, never after End.
- Passwords stored with Argon2id (never plaintext), traffic over
HTTPS, mobile auth token in Android's EncryptedSharedPreferences.

- On first launch, grant "Allow all the time" location access so
the recorder can keep running with the screen off.
