TravelKit

TravelKit is a travel companion that works fully offline by default. Everything runs and stores data locally on your device — no account, no backend, no sign-in. The one exception is the currency calculator's optional live-rate refresh, which calls a free, keyless exchange-rate API when you're connected.

FEATURES

PRIVACY

Nothing is uploaded anywhere. Your trip data and encrypted passport information live in the app's private storage and are excluded from Android's auto-backup, so passport data never leaves your device, even via backup.
