What "screen privacy" actually means (two different problems)
The first problem is overlay and hide: sensitive apps, notifications, the Dock, or desktop clutter should never appear in the shared image. Tools like Stealthly, CleanSlate, and Privacy Screen Sharing Tool tackle that by hiding elements, enabling Do Not Disturb, or feeding viewers a filtered mirror window instead of your raw desktop.
The second problem is redaction while staying productive: you still work across multiple windows, but viewers should not read background email, chat, or internal docs. Window-level blur tools like Veil keep your presentation app sharp while softening everything else; region-blur apps like BlurScreen let you mask specific rectangles. Screenshot redactors like Cloaked and Xnapper belong in a third bucket—they protect still images, not a live share.
The 7 best Mac screen privacy apps for 2026
1. Veil — best for keeping one window visible
Veil for Mac is built for live screen sharing when you need one app readable and everything else protected. Toggle it from the menu bar before you join Zoom, Teams, or Meet; Veil blurs background windows instead of hiding your entire desktop, so you keep spatial context without readable secrets.
Cover App pins the app you are presenting—Keynote, Chrome, your IDE—so it stays clear even when you briefly click elsewhere. Peek temporarily reveals all windows when you need to check Slack or a note, then drops back into blur with one shortcut. Follow-focus mode keeps the frontmost window clear when you prefer not to lock a single Cover App. Processing stays on your Mac; there is no cloud analysis of your screen.
Veil does not hide the Dock, desktop icons, or macOS notifications—pair it with Focus for banners. A 3-day trial leads into a $7.90 lifetime license on one Mac from veilformac.com. For the step-by-step workflow, see how to blur background windows on Mac before you share.
2. Stealthly — best for fully automatic hiding
Stealthly automates the pre-call cleanup ritual. The website build can detect screen sharing or recording and then hide desktop icons, wallpaper, the Dock, menu bar icons, and active windows while enabling Do Not Disturb. When you stop sharing, your workspace restores.
Pick Stealthly when you want hands-off presentation mode rather than manual blur toggles. The Mac App Store build is available but Stealthly documents fewer automatic triggers there. Requires macOS 14 or later.
3. Privacy Screen Sharing Tool — best free option
Privacy Screen Sharing Tool (PSST) creates a mirrored window that hides apps, windows, the Dock, and notifications you select while you still see them locally. Share that mirror in Zoom, Teams, or Google Meet instead of your full desktop.
Custom presets speed switching between client and internal modes, and v3.0 adds cursor overlay and auto-pause when you interact with a hidden window. The Mac App Store listing is free with optional Pro subscriptions; processing stays on-device. Requires macOS 15.6 or later per the store page.
4. BlurScreen — best for blurring on the fly
BlurScreen draws rectangular blur regions anywhere on screen with a keyboard shortcut—ideal when sensitive data sits inside one browser tab or panel rather than a whole window. It runs on Mac and Windows and processes locally per the vendor FAQ.
Choose BlurScreen when you need surgical masks during live calls or recordings, not automatic background-window blur. Paid tiers start at $19 one-time for one active device.
5. CleanSlate — best for a decluttered desktop
CleanSlate targets presentation polish: hide desktop icons, trim visible windows, block notifications, hide the menu bar, and apply focus dimming before or during screen share. It can auto-activate when it detects presenting and supports macOS 13+ on Intel and Apple Silicon.
Pick CleanSlate when your main risk is a messy desktop and distracting chrome, not unreadable text in background apps. Pair it with a blur tool if chat windows must stay unreadable while visible.
6. GeekBye — best for making an app fully invisible
GeekBye runs as a separate overlay window marked with macOS content protection so screen capture paths omit it from the shared frame. A visibility toggle shows a red border when you intentionally want the overlay on-stream.
Use GeekBye when you need private notes or tools that must not appear in recordings or shares at all—not when you want the audience to see blurred context. GeekBye documents platform limits (including Zoom version settings); test the recipient view before relying on invisibility.
7. Cloaked and Xnapper — best for screenshots (not live sharing)
Cloaked detects text and faces in still images and applies blackout, pixelate, or blur filters locally before you post or email a screenshot. Xnapper captures polished Mac screenshots with automatic sensitive-data redaction, annotations, and backgrounds—then you share the exported image.
Neither replaces a live privacy overlay during a call. Use them after the meeting for status updates, docs, or social posts where a static redacted image is enough.

How to choose: match the tool to the meeting
Pick Veil if you present from a full desktop or hop between apps and need one window to stay readable while everything else blurs. Pick Stealthly or CleanSlate if notifications, wallpaper, and dock clutter are the main embarrassment risks. Pick Privacy Screen Sharing Tool if you want a free App Store mirror workflow and can share that window instead of the entire display.
Pick BlurScreen when only part of a window is sensitive. Pick GeekBye only when an overlay must disappear from capture entirely—and test Zoom or Teams settings first. For chat-specific workflows, read how to hide chat windows during meetings; for live-share steps, see how to blur your screen during a screen share.
What macOS can do on its own (and where it falls short)
macOS gives you solid basics: share a single window in Zoom, Teams, or Meet; enable Focus or Do Not Disturb; hide apps with ⌘H or ⌘⌥H; and isolate work on another Space. Those tactics prevent many accidents when you plan ahead.
They fall short when you must share the entire screen, switch apps mid-demo, or keep background windows visible but unreadable. Nothing in System Settings blurs inactive windows for you. When you coach someone else through prep, share the guide to ask a client to hide sensitive windows before they hit Record.
FAQ
Is there a built-in privacy screen setting on Mac?
No. macOS does not ship a single privacy screen mode for screen sharing. You can share one application window, enable Focus or Do Not Disturb for notifications, hide apps with keyboard shortcuts, or work on a separate Space—but nothing automatically blurs or selectively hides arbitrary background windows while you present.
What's the difference between hiding a window and blurring it?
Hiding removes a window, app, or desktop element from what viewers see—the content is gone from the shared image. Blurring leaves the window visible as a shape but makes text and fine details unreadable. Pick hiding when you need a clean mirrored feed with specific apps removed; pick blurring when you still want context without readable secrets.
Do these tools work with Zoom, Microsoft Teams, and Google Meet?
Yes for the five live-share tools. Veil, Stealthly, Privacy Screen Sharing Tool, BlurScreen, and CleanSlate sit above the macOS display layer, so they work alongside Zoom, Microsoft Teams, Google Meet, and any other app that shares your screen or a chosen window. GeekBye depends on macOS content protection instead, and Zoom has changed how it handles protected windows between versions—test the recipient view before relying on invisibility. Cloaked and Xnapper are screenshot redactors: they do nothing during a live call.
Which one should I pick for client calls?
Pick Veil for client calls when you share your desktop or switch between apps during a presentation. Set a Cover App, toggle Veil on from the menu bar, and background windows blur while your presentation stays clear. Use Peek for a temporary full reveal, then return to protected mode. Pick Stealthly instead if you want automatic desktop cleanup when screen sharing starts.
Final thoughts
The best Mac screen privacy stack is usually two layers: macOS Focus for notifications plus one purpose-built app for windows. For most client-facing calls where you need clarity without leaks, Veil is the fastest path—Cover App, blur the rest, Peek when you need it. Add Stealthly or PSST when automatic cleanup or a mirrored feed fits better; keep Cloaked or Xnapper on hand for screenshots after the call ends.
