Call Blocker Free - Blacklist 5.5.12.00 requires the following permissions:

Allows applications to access information about networks.

Marker permission for applications that wish to access notification policy.

Allows applications to access information about Wi-Fi networks.

Allows applications to connect to paired bluetooth devices.

Allows applications to discover and pair bluetooth devices.

Allows an application to initiate a phone call without going through the Dialer user interface for the user to confirm the call.

Allows applications to change network connectivity state.

Allows applications to change Wi-Fi connectivity state.

Allows applications to open network sockets.

Allows an application to collect component usage statistics

Allows an application to read the user's call log.

Allows an application to read the user's contacts data.

Allows an application to read from external storage.

Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.

Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.

Permission an application must hold in order to use ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS. This is a normal permission: an app requesting it will always be granted the permission, without the user needing to approve or see it.

Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.

Allows access to the vibrator.

Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.

Allows an application to write the user's contacts data.

Allows an application to write to external storage.

Allows an application to read or write the system settings.
