MOV, WebM and MKV videos work the same way.

Does my audio leave my device?

No. Your audio is processed in your browser, on your device, so even long recordings start right away.

Is there a size limit?

No limits from us. Recordings of several hours need more memory and time; phones manage shorter files best.
