People often think about privacy only after a file reaches the Mac. But the handoff itself can be the weakest stage in the chain. If the easiest way to move a recording is to upload it into a cloud photo service, send it through a chat app, or bounce it through a personal drive, the privacy compromise has already happened before the file even arrives.
That is especially true for interviews, internal demos, research captures, personal archives, or any footage that should stay within a narrow operating boundary. In those cases, speed matters, but control matters more.
