    Reduced security risks: Limiting unnecessary permissions helps prevent apps
                           from collecting or sharing data without knowledge or consent.

                          Better control over device behaviour: Permissions help manage what apps

                           can change or access within the device, improving overall safety.

                      Working of App Permissions

                      App permissions act like rules that control what an
                      app is allowed to do on a device. Every app needs

                      permission  before  accessing  features  such as  the
                      camera,  microphone,  contacts  or location. When

                      the  permission  is  granted,  the  feature  becomes
                      available for the app to use.

                      Most apps ask for permission at the time of installation or when the feature is needed
                      for the first time. For example, a video-calling app will ask to use the camera and

                      microphone before starting a call. If the permission is denied, the app cannot use
                      that feature.

                      Permissions can be changed anytime from the device settings. This means a user
                      can remove access if the app seems unnecessary or unsafe. Some devices also

                      give warnings if an app requests a permission that does not match its purpose. For
                      example, a calculator app asking for camera access may be suspicious.

                      In simple  terms, permissions  ensure  that  apps  only  get  access  to  the  parts  of

                      the device that they genuinely need. This protects personal data and keeps the
                      device safer.

                         Android 11 introduced the ‘Ask every time’ option for location, camera and microphone
                         permissions, allowing users to grant temporary, one-time access to apps.

                      COMMON APP PERMISSIONS

                      Apps  request  permissions so they  can use specific  features of a device.  These
                      permissions help the app work properly but should be given only when necessary.
                      Understanding what each permission does makes it easier to decide whether to

                      allow or deny it.
