The recent terrorism headlines have renewed a debate over use of encrypted technology. Whatever side of the debate you're on, there's an issue related to encryption that is more likely to pose a risk in your daily life than global terrorism.

If the indicator shaped like a tiny paper airplane is on your phone screen right now, you are being tracked. Part of the compact that smartphone users make with technology companies to benefit from the Internet's services is sharing data about themselves. Clicking "yes" on Location Services without pause when an application asks for your location is a prime example of this trade-off.
