What stays private
Camera frames and raw hand landmarks are analyzed only in this browser session to map gestures to sound; they are not uploaded, saved, recorded, logged or sent to analytics. Stopping the experience releases camera and audio resources. MediaPipe may send Google non-input performance and utilization metrics. Vercel may process standard request metadata such as an IP address and browser user agent to deliver this page; camera frames and hand landmarks are never included.
