LeaveSafe watches a laptop you have stepped away from. Run it, scan the QR
code it prints with your phone, tap Arm, and walk away. The laptop watches its
own charger, lid, USB ports, screen lock, network and input; the moment any of
them changes, your phone goes off in your pocket and the laptop starts
sounding too.
No account, no server, no internet required. The phone talks straight to the
laptop over the local network, and the 16-digit pairing key never
leaves the two of them.
