About this app

Which apps on your phone deserve a closer look?

Privacy Sentinel helps you find privacy risks, identify suspicious app behavior, protect sensitive typing, and understand when apps use sensitive features on your Android device.

Use Privacy Checkup to review installed apps, spot concerning permissions, and focus first on the apps that may need your attention. Get clear, on-device protection and alerts for camera, microphone, location, overlays, background activity, and other privacy-sensitive events.

Privacy Sentinel is designed to explain what happened, why it may matter, and what you can do next—without overwhelming you with technical information or alarming you over every normal event.

YOUR INFORMATION STAYS PRIVATE

Privacy Sentinel is built around on-device privacy protection. Its detection and security checks are performed locally. Privacy Sentinel does not sell your personal information or build an advertising profile from your activity.

Privacy Sentinel does not replace safe browsing habits, Android security updates, or a dedicated antivirus product. It is a privacy and security companion that gives you clearer visibility, stronger protection, and more control over sensitive activity on your device.

Ratings and reviews

Privacy Sentinel is a game changer. It has opened my eyes to not-so-obvious security risks. Once I learned what some of my other apps were doing in the background without my knowledge, I deleted them immediately! Now I feel much more comfortable in the realm of digital security knowing that if an app ever poses a security risk, Privacy Sentinel will let me know. Also, its keyboard is great—I didn't even know other apps could be tracking my keystrokes as I type (scary). This app is a must-have!

this used to be a 5 star app until they locked features behind a paywall. The app was great until then. Also, the keyboard you can not change the language for it is just stuck in us english, so i have to disable auto correct.

it dont even matter to have a secure keyboard and if you was locked down on where you need it keyboards are nothing... cause telemetry is gone
