Your browser captures a webcam frame into a sandboxed <video> element. We never copy it to a server — there is no upload endpoint.

Pose landmarks and gaze direction are extracted on your own machine — in the browser tab for Demo Lab, inside the desktop app for the full product.

From landmarks we derive simple numbers: head angle, shoulder line, distance, blink rate. The frame is discarded immediately.

We store posture and eye-health scores — never images, never video, never anything that could identify you.
