LeaveSafe Atakan Kızılyüce

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 or Bluetooth, and the 16-digit pairing key never leaves the two of them.
