Do I need an OBD-II dongle or external tracker?

No. Vialog runs natively as an app on your vehicle’s digital dashboard without any external wiring or hardware.

Does Vialog work offline (e.g. underground parking or tunnels)?

Yes. It is completely offline-first. Trips are logged on the car and synchronised safely once mobile reception returns.

How does the tax authority view private trips?

Per GDPR requirements, private locations and addresses are not stored or uploaded. Only the aggregate distance is included in total mileage counts.
