Session audio, transcripts and notes stay on your computer. They are not sent to Safeclip. The main things that go over the internet: update checks to Safeclip, plus your sign-in and a license check at launch and daily if you sign in for Founding. No account is needed to use Safeclip. Model downloads on first run, from Hugging Face and GitHub. Media from a link you paste, fetched from that site. And two things that are off until you turn them on: cloud Ask with your own API key, and the local API, which lets another app on your computer read your transcripts if you give it library access.
The app has no analytics, telemetry or crash reporting. The full list also covers avatars, feedback you send and the rare fallback downloads.
