Try it — click any element above to blur it
One wrong click. Whole room sees it.
You're sharing your screen. A Slack DM pops up. An HR tab is open. A client's account number is visible. Sound familiar?
That Slack DM you didn't close
Mid-presentation, your screen shows a private message from your manager about someone's performance review.
Your salary on that HR dashboard
You're sharing your screen to show a workflow, and there's your compensation info in the sidebar.
Client data you can't legally share
You're demoing to a prospect, but the screen has real customer names, emails, and account numbers visible.
30 seconds. That's it.
Install. Click. Blur. You're already sharing privately.
