What Does Big Tech Know About You? Basically Everything

pcmag.com:

The stream of Facebook privacy scandals may have you questioning how much the social network and other tech giants actually know about you.

Here's a hint: practically everything.

Website Security Baron examined the privacy policies of Facebook, Google, Apple, Twitter, Amazon, and Microsoft and put together a handy infographic showing the types of data each company admits to collecting. For Facebook and others, data is money.

As you can see in the infographic below, Facebook is particularly data-hungry: It gathers information about your work, income level, race, religion, political views, and the ads you click in addition to more commonly collected data points such as your phone number, email address, location, and the type of devices you use.

"Facebook is unusually aggressive," Security Baron pointed out. "This data can be exploited by advertisers and (hopefully not nefarious) others."

Twitter, in comparison, is "comparatively hands-off," the site notes. The microblogging service, for instance, doesn't collect your name, gender, or birthday (as Facebook, Google, and Microsoft all do), but Twitter does know your phone number, email address, time zone, what videos you watch, and more.

Google and Microsoft are the other big players when it comes to collecting data.

"With Cortana listening in and Gmail seeing all of your emails, the ubiquitous nature of Google and Microsoft gives them access to an uncomfortably large amount of your information," Security Baron wrote.
