Privacy and Security Options in Android Guide

Privacy Options in Android

From the privacy section in the operating system settings, users can control a number of options, such as the permissions that each application gets, notifications and the information and activities that Google stores about the user.

  • From the “Settings” menu, tap “Privacy” as shown in the following picture:


  • Tap “Permission manager” to control the permissions that every application gets.

  •  From “Permission manager” the user can review all the permissions and the applications that have the authority to use those permissions. Tap on any permission and all the applications that have the authority to use this permission will appear.
  • It should be noted that the operating system automatically revokes the permissions for unused apps, but it is advisable to review all permissions and revoke unnecessary permissions.
  • For example, it is possible to revoke the authority to access the “location” for all applications except for the maps application.

  •  There are three options in permissions that each user can choose from according to their need, and they are as follows:
    1. “Allow only while using the app”, which means the application can use the permission while using the application only.
    • 2. “Ask every time”, this will require the application to ask for permission every time, and the user can accept or reject.
    • 3. “Deny”, and it is to deny or revoke permission.
  • The aforementioned means that the user has the right to control the permissions according to their need and their usage of the applications. For example the Signal instant messaging application can be given the authority to use the camera only while using the application, or the user could require Signal to ask for permission every time they want to send a picture or make a video call, and finally the app can be prevented from using the camera at all.

Disable Displaying Characters While Typing Passwords
