Your email, your key, and an anonymous machine fingerprint so one key stays on one PC. That's the whole account.
No telemetry, no tracking, no ads, no analytics. The app flies fully offline except licence checks and the terrain tiles it needs for the route.
Only what you press SEND on: aircraft, route and the log. Nothing leaves your PC otherwise.
