About this app

Do you feel like someone is spying on you from behind? Behind You is your personal guardian. Using the front-facing camera and an ultra-fast local AI engine, the app detects in real time if someone is looking at your screen over your shoulder. It runs in the background so you can use your phone as usual, but it activates immediately if intruders are detected.

It's perfect for commuting on public transport, working from cafés, co-working spaces, protecting sensitive work documents at the office or traveling through airports and stations.

• Background detection: Activate protection and continue browsing as usual. Behind You counts people and eyes in your surroundings while you’re using any app (chat, email, gallery, banking, etc.).
• Smart and customizable floating indicator: A small colored widget stays on the screen and keeps you informed in real time about your privacy: green (safe), yellow (caution, someone nearby), and red (alert! A peeping tom has been detected).
• Battery savings: To conserve battery life, Behind You uses an adaptive cycle. It scans less frequently when everything is quiet and increases monitoring only if it detects nearby movement.
• Guaranteed privacy: Everything is processed 100% on your device, without sending photos or data to the internet. Local facial detection avoids storing personal information; no remote servers are involved. Your data is always under your control!
• Premium Version: Subscribe for unlimited sessions, ad-free use, and advanced features such as automatically dimming the screen or taking a photo when someone is watching you.

Free users enjoy 15-minute detection sessions and can extend them by watching a rewarded ad for an extra hour.

Required permissions: The app requires access to the camera and permission to “Show over other apps”.

Ratings and reviews

Just downloaded it yesterday and I finally feel safe. but there's a few problems here and there, I tried to enable auto picture intruder and kept refusing and make the time longer, since some of us are young and won't be allowed to get plus. That's all I ask, but it's a good app. Might even recommend it to people👍🏻

okay,I tested this app and it's pretty good,the issue is that the dot when it does go red,even if I move away from someone stays red,I have to use live preview (which lasts 15 mins on free) to recalibrate it and make it see no one is looking at my screen,can you fix it?

A very simple and cool app—the first of its kind I've used. I wish the red indicator could blur the entire screen to hide its contents. 👍 up to the developer.
