For schools and IT

PadLink runs on the teacher's own PC. There's no PadLink server, no account with us, and no analytics or tracking.

Student privacy

Students don't create accounts. They join with the lesson's code and pick their name from the teacher's class list.
Student boards, raised hands and poll answers are kept only in the PC's memory during the lesson, and are deleted when the class closes.
Class lists hold names and, if the teacher chooses, a team and seat number. Nothing else.
Google Drive: PadLink only gets the files the teacher picks, and never changes or shares anything in their Drive.

On simple networks, the iPad and Chromebooks connect straight to the PC.
Where they can't, Remote mode connects through Microsoft's encrypted Dev Tunnels relay over port 443, like a normal website. It needs a one-time sign-in on the PC with a GitHub or Microsoft account.

PadLink checks for updates by itself, and every update is checked against PadLink's own signature before it installs.
