Frequently asked

Does the app need an account? No. Everything is stored on your device. There is no sign-up, no cloud, no tracking.

Is the calculation official? The engine follows the Schengen 90/180 rolling-window rule and is tested against the official European Commission calculator's behaviour. It is an aid, not a legal document — always verify with official sources.
