Service terms

FlightCal is operated by Sibyl Capital LLC. For support, email flightcal@sibylsignal.com. Apple's standard App Store EULA applies unless Sibyl Capital LLC provides a custom EULA.

The service

FlightCal monitors selected flights and shares fare observations and alerts. FlightCal does not sell tickets or make bookings. Prices and availability can change; verify details with the booking provider before purchase.

Accounts and subscriptions

Keep your sign-in details secure and your saved flight settings accurate. Plan features and prices are shown in the app before purchase. Apple processes App Store subscriptions and manages renewal, cancellation, and refund requests. Deleting your FlightCal account does not cancel a subscription.

Acceptable use

Use FlightCal lawfully. Do not interfere with the service, evade provider controls, or redistribute third-party data without permission. FlightCal may limit searches when a service dependency is unavailable.
