When school leaders ask for visibility into independent study, the market mostly offers surveillance: screen recorders, keystroke counters, app blockers with dashboards. Students learn to route around these within a week, and trust goes with them.
The useful question is not "what is the student looking at right now?" It is "was the work planned, and did it happen?" Those are answers a school can act on. A head of year who knows that a student has rescheduled the same essay five times has something concrete to talk about. A screen-time graph offers nothing but an argument.
We built the Lock In console around the work, not the student's screen. Sessions planned, sessions completed, deadlines at risk. It turns out that is also the version students will accept, because it measures the same thing their teachers already mark: whether the work got done.
