Live Reel Coach is built to send as little as possible off your phone. This page says exactly what does and doesn't leave the device, and what we track about how the site itself is used.
Pose tracking and pace detection run entirely on your phone, in the browser. No video frame, no audio, and no pose landmark is ever sent to a server. The recorded video of your take (if your browser supports it) stays in the tab — it is never uploaded — until you save it to your phone or leave the page.
When you finish a take, we send one anonymous record: three percentage scores (framing, steadiness, pace), a count of which coaching cues fired, the take's duration, the observed frame rate, and a coarse platform hint (e.g. "iOS Safari"). There is no account, no name, no email, and no identifier that ties a scorecard to a person or a device across visits.
We use a self-hosted analytics tool (Umami) to see how the site itself is used — page views, and, on the pages with an interactive flow, a recording of on-screen interaction (clicks, taps, scrolling). This is not a recording of your camera or microphone — it's a replay of what happened in the browser UI, the same category of data a support tool would capture.
