This is what's known as predictive modeling, and it requires nothing more than your cellphone data.
yup.
If you want to avoid some surveillance, the best option is to use cash for prepaid cellphones that do not require identification. The phones transmit location information to the cell carrier and keep track of the numbers you call, but they are not connected to you by name.
as mentioned above, that's not much protection. you can be linked by behavior and propinquity, if not by name. strong un-link-ability is an odyssey...
