Contrail Privacy Policy
Anlia Studio · Last updated 12 November 2026
Contrail is a flight tracker for iPhone. It's built so that your information stays on your iPhone. Anlia Studio does not run servers for Contrail and does not receive, collect, sell or share any of your data.
What stays on your iPhone
- The flights you add, your seat numbers and your logbook.
- Your settings (theme, units, notification and import choices).
- Your flight data API key, which is kept in the iOS Keychain.
Deleting the app removes all of this.
Calendar
If you turn on calendar import, Contrail reads your calendar events on your iPhone to find flights (for example "WF 920 Bodø – Tromsø"). The reading happens on the device. Event contents are never sent anywhere. You can turn this off at any time in Contrail's settings or in iOS Settings → Privacy & Security → Calendars.
Flight data services
To show real flight status, Contrail can connect to FlightAware AeroAPI using an API key that you create in your own FlightAware account. When you use this, your iPhone sends flight numbers and flight identifiers directly to FlightAware, together with your key. FlightAware's handling of that request is covered by FlightAware's privacy policy and your agreement with them. Nothing passes through Anlia Studio.
Without a key, Contrail uses simulated data and makes no flight data requests.
Maps and notifications
Maps are provided by Apple Maps (MapKit). Flight alerts and Live Activities are scheduled locally on your iPhone; Contrail does not use push notification servers.
Tracking, ads and analytics
Contrail has no ads, no analytics, no tracking and no third-party SDKs. It does not use your location.
Children
Contrail does not knowingly collect information from anyone, including children.
