At a time when your ISP is tracking your online activities, sites you visit are doing the same (even the one you do not visit are able to track you), Google is not to be left out in the game, and the NSA is tracking everybody else, it’s easy to be depressed.

There are things you can do to regain some semblance of privacy in your life, but with the wide variety of ways used to track you, only the most paranoid and tech-savvy has the skills to put up a good fight.
