So some questions:

> with the privileges of the Bluetooth daemon

Which priviliges is that? Can it access user data? Snoop on input/output?

> For some devices, the Bluetooth MAC address can be deduced from the WiFi MAC address

So if wifi is off, I'm safe?

I have bluetooth on all the time, because it automatically pairs with my car for cellular and audio, and turning it on and off would be a hassle. I rarely, however, use wifi unless I have to download a very big amount of data, which is almost never.
