I've built a privacy focused macOS app which makes use of a locally running neural network (YuNet), to notify you if other people are looking at your screen. YuNet runs fully on-device with no data leaving your computer.

The app utilises a 230kb facial detection model, which takes images from your webcam and checks for any faces entering the viewing field of your webcam. If the number of faces exceeds the threshold an alert will be shown.

Built with Python + PyQt, the YuNet code comes from OpenCV. Currently it's a macOS app only, however I will be widening access to windows devices soon.

I'd love your feedback on the app, I look forward to reading your comments on thoughts and future directions you'd like to see!
