Everything you enter stays on this device. Your stops, addresses, odometer readings, home address and identification number are saved only in this phone's own storage. Nothing is sent to a website, a server, or your employer, and no one else can see your log — not even whoever set this up for you. It leaves this device only when you choose to print your log or send yourself a copy — or if you tap a “look it up” link, which opens Google Maps with those two addresses, exactly as if you had typed them into Maps yourself.
