Day One Journal 1.1.4 requires the following permissions:

Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.

Allows applications to access information about networks.

Allows applications to access information about Wi-Fi networks.

Allows applications to open network sockets.

Allows an application to manage access to documents, usually as part of a document picker.

Allows an application to read from external storage.

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.

Allows an app to use fingerprint hardware.

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

Allows an application to write to external storage.
