# Head-Tracking Privacy Apps Max Rovensky Turns AirPods into ShyGlass Screen Guard By Amy Duong | Written with AI assistance | Published 2026-10-14 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/head-tracking-privacy-apps References: [9to5mac](https://9to5mac.com/2026/10/12/security-bite-this-nifty-privacy-app-blurs-your-mac-screen-the-second-you-look-away)  Developer Max Rovensky created ShyGlass to blur a Mac display when AirPods sense the wearer has turned away, giving laptop users in cafés, trains, and hotel lounges a quick shield from nearby eyes. The blur lifts when the user faces the screen again, turning a glance away into an [automatic privacy step](https://www.trendhunter.com/trends/wipr-filtr) instead of a manual shortcut. ShyGlass taps the same [AirPods motion data](https://www.trendhunter.com/trends/airpods-pro-3) used for dynamic head tracking, then watches for drift from a calibrated center point set in the menu bar. The blur starts at 15 degrees by default. The $4 app runs on macOS 14 or later and requires supported AirPods. At $4, ShyGlass turns an existing Apple audio feature into a low-cost privacy layer for people who work on the move. The AirPods requirement keeps it niche, but it also shows how built-in sensor data can widen the market for [lightweight screen-protection apps](https://www.trendhunter.com/trends/blur-it).
