The miracle of the modern app is that it can help you in astounding ways. By analyzing your data, your movements, and your computer, it can make you more efficient and save you a lot of steps.

But plenty of people are creeped out by the notion of software tracking their movements around town, tracking the Web sites they visit, or even listening to their world through the built-in microphone. These on/off switches, therefore, are intended to shut down your apps’ access to every conceivable shred of useful data about you and your PC.
