This app can access and turn on Bluetooth without permission. It says it needs it to check for exposure, but does not explain why. I also can't remove it as a permission because it doesn't even ask for it like most applications would. I can't understand why it can't use my location for finding exposure which is also does not ask for permission to do; in fact there are no permissions at all. I'm uninstalling because I don't want my Bluetooth constantly turned on without an ability to control it.
