Mask any sensitive area
Cover or block parts of your Mac screen—names, emails, balances, messages, tokens, or internal UI—without changing the source app.
Cover Any Part of Your Mac Screen
Place resizable screen overlays to cover or blur any part of your Mac screen—hide sensitive info and block distractions during recordings, demos, presentations, and everyday work.
Screen overlays for Mac
Floating or per-window
Cover or blur instantly
Attach masks to app windows and fine-tune each mask with per-item settings like opacity, click-through, spotlight, and border style. 
Compare different mask styles at a glance, including blur, solid fill, custom colors, and spotlight effects. 
Manage all masks in one place, including floating masks and app-attached masks for specific windows. 
Set default mask appearance with background style, opacity, blur radius, cursor spotlight, click-through, and border options. 
Assign keyboard shortcuts for showing the app, adding masks, selecting windows, and clearing or restoring all masks. 
General settings let you control launch behavior, menu bar visibility, and apps excluded from the mask picker. 
The About screen highlights Cloaky Pro features, one-time unlock pricing, and your current activation status. 
A dark appearance is available too, with the same mask controls and list management in a lower-glare interface.
Built for privacy without breaking your workflow
Cloaky is not a screenshot blur toy. It gives you live, adjustable screen overlays (privacy masks) that cover or blur parts of your screen while you work, present, or share your full screen.
Choose the right masking style
Blur part of your screen or use a solid screen overlay. Switch between blur, fills, spotlight, and custom colors to hide details or guide attention.
Stay fast during live work
Use floating masks or per-window screen overlays with shortcuts, so hiding private areas feels instant—not interruptive.
Where Cloaky fits best
Cloaky is most valuable when you need to share your Mac screen but hide part of the screen. It keeps private or distracting areas out of view while you stay in your normal workflow.
Internal demos and reviews
Show real workflows while you cover parts of the screen on Mac—tokens, customer data, or internal-only UI.
Live presentations
Present flows or dashboards while you blur part of the screen on Mac to keep private details out of view.

Does Cloaky modify the original app?
No. Cloaky adds masks on top of what you see, so the underlying window stays unchanged.
Can I cover or blur part of my Mac screen?
Yes. Cloaky is a Mac screen overlay (screen mask) that lets you cover or blur any part of your screen while recording or sharing.
Can I attach masks to a specific window?
Yes. You can create floating masks or attach masks to particular app windows depending on the workflow.
Can I use something other than blur?
Yes. Cloaky supports solid masks, custom colors, spotlight behavior, opacity control, and border options.
Is it useful only for screen sharing?
No. It also helps with live demos, office displays, internal reviews, and any workflow where private content stays on screen.
Will masks appear when I share a single app window?
No. In our testing, masks appear when sharing your full screen, but not when a meeting tool captures only a specific app or a single window.
Why does single-window sharing behave differently?
That mode captures the source app window itself, not the full display where Cloaky renders its overlay on top.
