Where does student audio, video, and practice data go?
The current public demo is browser-local: video is analyzed on the device, and session history is stored in browser localStorage on that device. Video never leaves the device. Spoken audio goes to the browser's speech service (Google, Microsoft or Apple, depending on the browser) to make the live transcript. BrightSpeaker does not send student session data to a BrightSpeaker server in this demo path.
