I’m slightly paranoid about privacy, and what permissions that an App has.
The Keypad – Bluetooth Keyboard App only has permissions to access bluetooth and to launch the bluetooth settings. It does not have access to the internet, so it cannot send any data out, or even show ads.
I’m including here a screenshot of my app permissions if you are curious.
This was a conscious choice, even though it means that I cannot integrate with tools that will allow me to track crashes using fabric or something similar.
