You need to turn off bluetooth on your phone too.

  Huh, I wonder if that means you should disable WiFi discovery too. Never thought I'd be that glad to be in the habit of mobile data only (not that there aren't problems there too...)

    Yes, WiFi discovery can be used to track to too.

    Any signal your phone emits with identifying information could be used. Why not your cellular signal?

      I'm a lot less concerned about retail stores tracking me via cell signal, as it requires much more specialized hardware/software - meanwhile, it's likely feasible to modify extant in-store WiFi infrastructure to track that.
