Personal Privacy Guard is an Android app designed to protect your private data from intruders and snoopers. It does this by locking apps, photos, videos, and other sensitive information with its own combination lock or pattern lock. With this app, you can prevent others from accessing your private data, changing your settings, or deleting important content.

The app uses the AccessibilityService API to access other application running information such as package names, activity names, etc. This information is not saved or shared and is only used to determine whether the currently launched application needs to be locked. With Personal Privacy Guard, you can have peace of mind knowing that your private information is secure and protected.
