Behind You

Have you ever felt that uncomfortable sensation that someone is reading or watching your private chats, pictures, or banking details over your shoulder? Whether you are on a crowded subway, working in a busy coffee shop, or sitting at the office, shoulder surfers are everywhere.

Behind You is your ultimate silent guardian. Using your device's front-facing camera and advanced, ultra-fast, lightweight local AI, the app runs quietly in the background to detect if someone else is staring at your screen from behind you.

🛡️ Key features:

• Real-Time Background Detection
Activate the detection and use your phone normally. Counting the people and eyes looking at your screen.

• Smart Floating Indicator (Traffic Light System)
A tiny, customizable floating LED widget stays on your screen to keep you informed of your privacy status in real-time:
🟢 Green: Safe. Only you are looking at your screen.
🟡 Yellow: Caution. Another person is detected nearby, but they aren't actively staring at your screen (yet).
🔴 Red: Alert! A pair of eyes has been caught snooping directly on your device.

• Smart Battery Saving (Adaptive Duty Cycle)
Constantly running a camera can drain your battery. Behind You features a smart sampling cycle. It scans in brief intervals when everything is safe, only ramping up to real-time tracking when a potential intruder is nearby. Protect your privacy without sacrificing your battery life.

🔒 Your Privacy is Our Top Priority
We believe that a privacy app should never compromise your data.

100% On-Device Processing: All face and eye detection is processed locally on your phone.
