A recent Pew survey revealed that 57% of Americans are asked to agree to a privacy policy on a weekly basis, yet only 9% read the full contents before accepting the terms. That's a whole lot of people who aren't in the know when it comes to data permissions.

Companies want your data and often make privacy agreements needlessly complex in order to strong-arm you into blindly giving it away. This "freeware" software model – wherein a company effectively offers the use of one of its apps for free in exchange for access to user data – has exploded in popularity in recent years. Companies may then use this data to inform targeted advertising campaigns, refine their own product, or sell user data to another company.
