Files stay on your device. Audio uses a small MP3 encoder; video uses built-in browser codecs and a lightweight JS helper when available. On browsers without suitable codecs, video may be saved as WebM. Advanced FFmpeg mode (≈32 MB) is offered only with your permission. Native video recording may run in real time; keep this tab visible until processing finishes.
