General Apps
Protects against the following threat(s):
We recommend a wide variety of Android apps throughout this site. The apps listed here are Android-exclusive and specifically enhance or replace key system functionality.
Shelter
If your device is on Android 15 or greater, we recommend using the native Private Space feature instead, which provides nearly the same functionality without needing to place trust in and grant powerful permissions to a third-party app.
Shelter is an app that helps you leverage Android's Work Profile functionality to isolate or duplicate apps on your device.
Shelter supports blocking contact search cross profiles and sharing files across profiles via the default file manager (DocumentsUI).
Warning
When using Shelter, you are placing complete trust in its developer, as Shelter acts as a Device Admin to create the Work Profile, and it has extensive access to the data stored within the Work Profile.
Shelter is recommended over Insular and Island as it supports contact search blocking.
Secure Camera
Protects against the following threat(s):
Secure Camera is a camera app focused on privacy and security which can capture images, videos, and QR codes. CameraX vendor extensions (Portrait, HDR, Night Sight, Face Retouch, and Auto) are also supported on available devices.
Downloads
Main privacy features include:
- Auto removal of Exif metadata (enabled by default)
- Use of the new Media API, therefore storage permissions are not required
- Microphone permission not required unless you want to record sound
Note
Metadata is not currently deleted from video files but that is planned.
The image orientation metadata is not deleted. If you enable location (in Secure Camera) that won't be deleted either. If you want to delete that later you will need to use an external app such as ExifEraser.
Secure PDF Viewer
Protects against the following threat(s):
Secure PDF Viewer is a PDF viewer based on pdf.js that doesn't require any permissions. The PDF is fed into a sandboxed WebView. This means that it doesn't require permission directly to access content or files.
Content-Security-Policy is used to enforce that the JavaScript and styling properties within the WebView are entirely static content.
