BioKids
Parental controls for Debian 13 that keep everything on the computer
...The child taps their picture to sign in and gets a launcher of big tiles instead of a desktop; a ring shows the minutes left, and two voices, Zio and Sio, say when time is nearly up.
The parent sets the rules from a panel on the same computer, or on their phone over their own Tailscale network: daily limits that changing the clock cannot fool, allowed hours, a local web filter, one-tap answers to requests for more time, history, and a live view of the screen that the child always sees.
Nothing about the family leaves the computer: no account, no telemetry, no BioKids server. An optional assistant runs on the machine itself.
The ISO is Debian 13 with BioKids and installs beside Windows; check it with the signed SHA256SUMS next to it. ...
