"The device in your purse or jeans that you think is a cellphone — guess again. It is a tracking device that happens to make calls. Let’s stop calling them phones. They are trackers."
"Thanks to the explosion of GPS technology and smartphone apps, these devices are also taking note of what we buy, where and when we buy it, how much money we have in the bank, whom we text and e-mail, what Web sites we visit, how and where we travel, what time we go to sleep and wake up — and more. Much of that data is shared with companies that use it to offer us services they think we want."http://www.propublica.org/article/thats ... my-tracker
