Focus check-in — optional
Nudges you if you drift off mid-session. Everything happens on this device.
- Turn it on, then press Start. Your browser asks for the camera once.
- It checks roughly every 2 seconds whether someone is at the screen.
- You get a nudge only after you've clearly been away — never for glancing at your notes.
- Turn it off at any time and the camera stops immediately.
This is the picture being checked, on your device. It is not recorded and never leaves this browser.
Nothing that could identify you. Video is never recorded and never uploaded — frames are examined in your browser and discarded. All that reaches us is a count per minute: how many checks saw someone, how many didn't. No images, no face data. It's a rough signal, not a measurement, so treat it as a nudge rather than a verdict.
