leavesafe · a device security monitor
it watches the laptop you walked away from
six sensors on the machine itself. if one of them stops agreeing with the reading it took when you armed, the laptop sounds and your phone is told, straight away.
the part that does the watching is open source — see what that means
what it does
six things, one machine
- it watches
- charger, lid, usb, screen, network, keys — on the computer you leave behind
- it reacts
- the moment a sensor disagrees — a siren on the machine itself, getting louder
- it needs
- no account on the open-source version — it reaches no server at all. pro signs in with a sixteen-digit key, and still no e-mail

the core is open source
the watcher — the part that reads the sensors and sounds the alarm — is free and open source. it runs entirely on your own machine, needs no account of any kind and talks to no server. you can read every line of it.
that is the whole product, not a trial of one. nothing is held back to make you pay: the paid tier adds reach, and takes nothing away.

same wi-fi, or any network
the free version talks to your phone across your own wi-fi. pro adds an account and a real app, so the alert finds you on any network at all.

inside your own wi-fi this is the whole product. six sensors, the siren, the audit log, the disarm pin — open source, no account, no server. every phone on that network hears it, and the laptop sounds whether a phone is awake or not.
pro is that same product on any network. the alert does not stop at the edge of the wi-fi — it finds you on mobile data, in another building, in another city. and once there is an account there is a list: every machine you have paired, what it last reported and when it was last seen, with any of them signed out from wherever you happen to be standing. nothing is removed from the free version to make room for it.

invite one person
the only way anyone sees your machine is a code you hand them, and it works once
- a café, and you have to get upthe laptop is armed on the table. your own phone is at three per cent, on a charger by the wall.
- you hand your friend the codea qr across the table — good for an hour, a day, a week, a month, or until you take it back
- their phone watches it for youthey see whether it is still armed, and they get the alarm the moment a sensor disagrees. that is all they see — not your account, not your other machines, not where you are.
either of you can end it, and if neither does, it ends by itself
questions
before you download
does it need an account?the open-source version does not — it runs on your machine and reaches no server. pro does: an account that is a sixteen-digit key, with no e-mail address and no password attached to it.
what if my phone is asleep?the laptop's own siren sounds regardless. the phone is the convenience, not the alarm.
why does the free version need the same wi-fi?because there is no server in the middle. your phone talks straight to your laptop, which only works while both are on the same network.
is the installer signed?not yet, so windows will warn you. the sha-256 is printed beside the download so you can check the file yourself.
