Mac privacy software · free vs $2.99
Mac privacy screen app. Hide sensitive windows.
Hide selected windows, cover sensitive areas, and use local face detection. Try the free Lite app before choosing the $2.99 full version. This is software, not a physical privacy filter.

Quick answer
Use a Mac privacy screen app for software controls, not viewing-angle protection.
Anti-spy screen Lite is the lower-friction choice for trying local face-count detection, protected app hiding, Privacy Block, and Presenting Mode. The full Anti-spy screen app is a $2.99 one-time purchase. Both current US listings require macOS 13.0 or later. Use a physical privacy filter instead when the goal is to narrow the display's side viewing angle.
Try Lite before paying if you have not tested camera placement, lighting, and app-hiding behavior on your Mac.
Open the full listing when you prefer a one-time purchase and want to compare the latest release details before buying.
The full listing says face detection runs locally without internet access and shows an App Privacy label of Data Not Collected.

Know the boundary
This is software privacy, not a physical privacy filter.
Anti-spy screen responds to configured privacy events by hiding selected apps or covering part of the display. It does not narrow the physical viewing angle of the Mac screen, and it is not a replacement for checking the meeting preview or choosing the correct window to share.
Choose the email, browser, notes, or other running apps that should disappear when the configured threshold is exceeded.
Privacy Block provides a draggable, resizable, adjustable-opacity cover for content that should stay out of view.
Use the Mac screen-sharing privacy checklist before presenting, including notification and window-share checks.
