What actually leaks when you share your screen
The surprising amount of private information that rides along on a normal screen share — and where it comes from.
Most screen-share incidents aren't dramatic. They're small: a banner notification slides in, a Slack sidebar shows an unread channel name, a browser tab title gives away what you're working on next. Individually harmless. On a recorded client call, permanent.
The four usual suspects
- Notifications — Messages, Mail, Slack, and calendar banners that appear on top of everything.
- Open windows — a DM thread, an inbox, a document from another client.
- Tab and window titles — they often reveal names, deals, or unreleased features.
- The Dock and menu bar — badges and icons that hint at what else is running.
Why 'just close everything' fails
The advice to close every app before a call sounds simple, but it breaks the way you actually work. You need Slack open to grab a link. You need your notes. You need the very apps you're trying to hide.
ScreenVeil takes the opposite approach: keep everything open on your Mac, and shape what the audience sees instead.
