Gaze Guard

What is Gaze Guard?

Gaze Guard is a macOS menu bar utility that helps protect sensitive on-screen content by automatically blurring it when you look away. It’s designed to reduce the risk of shoulder surfing—when someone nearby tries to view your screen over your shoulder.

The app uses on-device face tracking to detect your gaze orientation and the presence of people near your display. When a trigger is detected, it applies a blur overlay to the screen or to selected apps, letting you keep your workflow private in shared environments.

Key Features

• Smart gaze detection with instant blur: When you look away from your screen, Gaze Guard blurs protected content immediately.
• Shoulder surfing detection: Detects if someone is looking at your screen over your shoulder and activates privacy mode.
• Selective blur for specific apps: Choose particular apps (e.g., Mail, Notes) to blur, instead of blurring everything.
• Adjustable shoulder-surfing sensitivity: In update notes, you can choose between “Anyone Nearby” and “Direct Gaze Only” detection behavior.
• Battery-efficient background operation: Includes an Eco Mode intended to minimize CPU usage while running in the background.

How to Use Gaze Guard

1. Install Gaze Guard from the Mac App Store.
2. Ensure the app has camera access, since it requires camera access to detect face orientation.
3. Open the app and configure which apps you want protected using the selective blur option.
4. Use your Mac normally; Gaze Guard monitors gaze/shoulder-surfing triggers and applies or removes the blur overlay automatically.

Use Cases

• Coffee shops and coworking spaces: Blur sensitive emails, documents, or chats when you glance away or when someone nearby might be viewing your screen.
• Open offices handling confidential work: Keep private notes or messages protected while you remain at your desk, without needing to manually lock or switch windows every time.
• Teaching or busy public environments: Use “Direct Gaze Only” detection to reduce false triggers in crowded locations where people may pass by or look generally in your direction.
• Home use with shared spaces: When someone approaches your workspace, “Anyone Nearby” can trigger protection more aggressively.
• Focused workflows that shouldn’t be fully obscured: Use selective blur so only certain apps are covered, allowing other non-sensitive windows to remain visible.

FAQ

• What does Gaze Guard blur—my entire screen or only certain apps? You can choose to blur the entire screen or select specific apps to protect.

• Does the app store or transmit images? The app’s listing states that no images are stored or transmitted.

• Does Gaze Guard require camera access? Yes. The listing notes that Gaze Guard requires camera access to detect face orientation.

• Is face detection done on-device? The listing says face detection is processed on-device using Apple’s Vision Framework, and that no camera data ever leaves the Mac.

• What are the system requirements? The app requires macOS 14.0 or later.

Alternatives

• Built-in macOS privacy/locking options: Use Screen Lock or other macOS privacy controls when you step away; these require manual triggering rather than automatic blur based on gaze.
• Blur/Privacy overlay utilities for specific apps: Look for tools that provide app-level blur overlays triggered by hotkeys or focus changes; these may not rely on gaze/shoulder-surfing detection.
• Screen mirroring privacy blockers / physical privacy filters: Physical privacy filters reduce viewing angles from the side, which can be helpful when you want privacy without software-driven camera-based detection.
• Remote-work privacy software (meeting and content protection): For specific workflows like calls and shared documents, some tools focus on protecting content during collaboration rather than real-time gaze-triggered blurring.
