Why Notifications Still Show While Screen Sharing
Notifications still show while screen sharing for three common reasons: Do Not Disturb is off, the app has its own notification system, or the notification is already inside the page you are sharing.
Fixing this means handling system notifications, meeting app notifications, browser notifications, and visible in-page content separately.
System notifications are still enabled
On macOS, use Focus from Control Center. On Windows, use Do Not Disturb in notification settings. On ChromeOS, use Quick Settings. If you only muted one app, other apps can still interrupt.
Browser notifications can bypass your mental checklist
Sites like Gmail, Slack, calendars, project tools, and chat apps may send browser notifications. Turn off browser notifications globally before important presentations or mute the sites most likely to expose private messages.
In-page notifications are not system notifications
A badge, sidebar preview, unread count, toast inside a web app, or chat panel inside the page is not a desktop notification. Do Not Disturb will not hide it because it is part of the page you chose to share.
Close the panel, switch to a clean workspace, or blur the page content.
You shared too much surface
If you share your entire screen, every notification on that monitor can become visible. Share a single tab or window whenever possible, then confirm the meeting banner shows the correct surface.
Practical examples
Why the fix can look like it failed
- You muted macOS notifications, but the web app showed an in-page chat toast.
- You muted Teams, but Chrome still had notification permission for Gmail or Slack.
- You shared the full screen, so a second app alert appeared over the window you meant to show.
- You turned on Focus after the call started, but an earlier notification was already visible on screen.
- You muted one workspace, but another account or browser profile was still signed in and active.
Where Safe Screen Share fits
Safe Screen Share is for legitimate calls, demos, recordings, and tutorials where you need the real page visible but not every private detail on it. It runs locally in your browser, detects sensitive fields like emails, phone numbers, payment data, and API keys, and can turn on automatically when a meeting starts.
You can add Safe Screen Share to your browser or see the pricing. It is a one-time purchase, not a subscription.

Frequently asked questions
Why did a Slack message show while Do Not Disturb was on?
It may have been an in-app message, a browser notification from a site with separate permissions, or a notification from a device/account not covered by that setting.
Does sharing a tab hide notifications?
It hides most desktop notifications from the audience, but it does not hide content inside the tab itself.
Should I turn off notifications or blur content?
Do both. Turn off new alerts and blur sensitive content already on the page.
