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.

Check out the full infographic to see what Facebook, Google, Apple, Twitter, Amazon, and Microsoft may know about you. For tips on securing your digital privacy, check our story, "Online Data Protection 101: Don't Let Big Tech Get Rich Off Your Info.

My Experience

I'm PCMag's managing editor for consumer electronics, overseeing an experienced team of analysts covering smart home, home entertainment, wearables, fitness and health tech, and various other product categories. I have been with PCMag for more than 10 years, and in that time have written more than 6,000 articles and reviews for the site. I previously served as an analyst focused on smart home and wearable devices, and before that I was a reporter covering consumer tech news. I'm also a yoga instructor, and have been actively teaching group and private classes for nearly a decade. 

Prior to joining PCMag, I was a reporter for SC Magazine, focusing on hackers and computer security. I earned a BS in journalism from West Virginia University, and started my career writing for newspapers in New Jersey, Pennsylvania, and West Virginia.

The Technology I Use

My little Florida beach bungalow is brimming with smart home tech. I have a smart speaker or display in every room, allowing me to control other connected devices by voice. The Nest Hub on my bedside table lets me set wake-up alarms, control my smart light bulbs, and set the temperature on my smart thermostat. I use the Amazon Echo Show 8 on my kitchen counter to browse recipes, reorder protein powder, check the weather, and watch the news while I do dishes. 

Because I suffer from allergies, air purifiers are essential. My favorite model is the Dyson Purifier Cool TP07, which doubles as a fan and continuously sends indoor pollution data to its companion mobile app. 

My pitbull Bradley sheds, so a good robot vacuum is a must. I currently use a premium Ecovacs Deebot that can both vacuum and mop, empty its own dustbin, and wash its own mop cloth. 

For fitness, I like to mix up my routine with cycling, indoor rowing, running, and strength training in addition to yoga. I take classes on the Tonal 2 smart strength training machine, I row indoors on an Aviron machine, and track my beach runs with an Apple Watch while listening to music on my Apple AirPods Pro. On the weekends, I love riding e-bikes like the rugged, beach-friendly Aventon Aventure for fun and fitness.

My job involves a lot of virtual meetings, so a quality webcam, microphone, and ring light are important. I use the Jabra PanaCast 20 webcam, the Elgato Wave: 3 microphone, and a Yesker tripod ring light. 

As for my preferred phone platform, I'm an iPhone person, but I've also extensively used Android for product testing.
