Your Location Data Is Not As Anonymous As You Think

We all know that our phones and apps track our locations – and it seems that most of us are resigned to the fact that too much of this data ends up in the hands of companies who want to advertise to us. Problem? Nobody thinks that the data is actually stored, or how anonymous it is not .

While it will take huge legislation to restrict or otherwise restrict data collection and how location data is used and transmitted, there are a few things you can do to try to minimize the flow of information that you share. Here are some tips to try:
