Zoom can't see your screen unless you share it. Zoom's own help center says hosts "cannot monitor your screen activities unless you choose to share your screen." When you share a window, participants see only that window. When you share your entire screen, they see everything on that monitor, including notifications.
Can a Zoom host see your screen if you don't share it?
No. Zoom states it plainly in Sharing your screen or desktop on Zoom: screen sharing gives "only the users, who choose to share their screen, full control over their own screen," and hosts "cannot monitor your screen activities unless you choose to share your screen."
A host has real powers in a meeting. They can mute you, ask you to turn on your camera, remove you, record, and decide who's allowed to share. Starting your screen share isn't one of those powers. The Share button is on your toolbar, and only you can click it.
There used to be one feature that came close. Zoom's "attendee attention tracking" told hosts when a participant had clicked away from the Zoom window during a share. Zoom removed it on April 1, 2020, during its privacy and security push that spring. If you read an older article warning that the host knows when you switch apps, that's the feature it's describing, and it no longer exists.
What can people see in each Zoom share mode?
| Situation | What the host and participants see |
|---|---|
| You're not sharing | Your video (if on), your name, your mute state. Nothing from your screen. |
| You share one window | Only that window's content. Other apps, notifications and the taskbar stay private. |
| You share your entire screen | Everything on that monitor: notifications, taskbar, every window you switch to. |
| You share one of two monitors | Only the shared monitor. The other one stays private. |
| You share a portion of the screen | Whatever is inside the green frame, including windows dragged into it. |
| The Zoom window itself | Hidden from your share by default, unless you turn on the setting to show Zoom windows. |
| Someone requests remote control | Nothing changes until you approve. Then they can control the shared screen. |
| The meeting is recorded | The recording holds what was shared and the video feeds, not your private screen. |
Can a Zoom host see your screen without permission?
No. Everything screen-related needs an action from you: clicking Share, picking what to share, approving a remote control request. A host who wants to see your screen has to ask.
Two things can feel like a host is watching, so it's worth separating them out:
- Focus mode. When a host turns on focus mode (common in classrooms), participants see only the host's video, while the host sees everyone. If you share during focus mode, the host can see your share even if other participants can't. You're still the one who chose to share.
- The share picker. When you click Share, Zoom shows thumbnails of your open windows. That picker is on your computer, for you. Hosts don't get a view of it.
When you share your screen on Zoom, can they see everything?
If you share the entire screen, yes, everything on that monitor, for as long as the share runs. That's the setting behind nearly every "oops" story. A few examples of what people forget is part of their screen:
- A Windows toast with the first line of a private message.
- The browser tab bar, which shows the title of every open tab.
- The taskbar, with unread counts on Outlook or Teams.
- The window you alt-tab through on the way to the one you wanted.
Share a single window and that list shrinks to one app. If your desktop is on a second monitor, share only the presentation monitor. And keep Zoom updated: in 2021 security researchers at SySS reported that Zoom through version 5.5.4 could briefly expose other windows placed over a shared window (CVE-2021-28133). Bugs like that are rare, but they're fixed by updating.
If Zoom can't see your screen, what can?
Zoom isn't the thing to worry about on a work laptop. Companies sometimes install employee monitoring or endpoint security software that can take screenshots or record activity, and that has nothing to do with Zoom. If your device is managed by your employer or school, assume their IT policy decides what's recorded, and read it.
On your own PC, the honest answer is that only apps you've given screen capture access to (on a Mac) or apps you've installed and are running (on Windows) can capture your screen. Windows doesn't ask for permission per app, which is one reason to be careful about what you install.
Curious whether Zoom notices other apps running alongside it, like an overlay? We answered that separately in Does Zoom detect overlays?
How do you keep apps private while sharing your screen on Zoom?
- Share a window instead of your screen. The step-by-step version is in our Zoom screen sharing guide.
- Turn on Do not disturb before you share, so toasts never appear. Our notifications guide covers Windows and Mac.
- Keep private windows on a monitor you don't share.
- Use a window that's excluded from capture. On Windows 10 version 2004 and later, an app can mark its own window with
WDA_EXCLUDEFROMCAPTURE. Zoom's capture then leaves that window out, even during a full-screen share. Our guide to hiding a window from screen share compares all four options.
AuraCloak is an AI chat overlay that Zoom leaves out of your screen share, so your notes stay on your side.
Get AuraCloakAuraCloak is an invisible AI overlay for Windows that uses option 4. It sits on top of your Zoom window or slides, and viewers see what's underneath it. It's not magic, though: anyone who can physically see your monitor, or point a phone at it, sees the overlay.
FAQ
Can the Zoom host see my screen without me sharing?
No. Zoom's help center says hosts cannot monitor your screen activities unless you choose to share your screen. A host can ask you to share, but only you can start a share.
Can Zoom see my other tabs when I share my screen?
If you share your entire screen or your browser window, participants see the tab bar, so they can read the titles of other tabs. They can't see the content of tabs you don't open. Sharing a different app's window keeps your browser out entirely.
Does Zoom tell the host if I switch windows?
No. Zoom removed its attendee attention tracking feature, which flagged participants who clicked away from Zoom, on April 1, 2020. If you're sharing your entire screen, though, people can see you switch windows.
Can a Zoom host take control of my screen?
Only if you approve it. A participant viewing your share can request remote control, and nothing happens until you accept. You can take control back at any time.
Can the Zoom host see my second monitor?
Only if you share it. When you share one monitor, the other one isn't sent. Sharing a single window keeps both monitors private except for that window.
