Privacy you can read in one glance

Your video is analyzed on your device. Raw video is off by default. Donating data to research is its own separate opt-in.

You control three things separately

Turning one on never silently turns on another.

Essential scan processing

Required

We need camera access to compute your scan and show results on this device.

Raw video retention

Off by default

Keep raw video so you can compare scans later and optionally share with a coach.

Research opt-in

Off by default

Help improve model accuracy by donating de-identified scan data. Raw video is only used if you explicitly allow it.
