How to opt out of Facebook data sharing
Facebook and other companies often buy data from data brokers in order to sell advertisers more targeted ad space on their platforms. Here's how to keep your data safe.
Facebook knows a lot about you. I mean, a lot. If you've ever been creeped out by a scarily on-point ad while visiting Facebook, that's why. But some of you might wonder where Facebook gets its data. The answer is simple: data brokers.
A data broker collects your information from various sources and depending on the broker in question, this information could come from online, offline, or both. Whenever you make a purchase online or utilize your grocery store's loyalty card, the data on your purchases is collected by at least one company. Facebook buys this data and, letting advertisers use it to more specifically target ads towards you. Though Facebook says that the data brokers anonymize what they collect, the details can still be matched against your Facebook profile, building for Facebook and its advertisers a complete picture of who you are.
Creepy, right?
There's some good news here, though. You can opt-out of this sort of data collection at a lot of data brokers including the companies with which Facebook has partnered. And you can do this on top of using security features such as limiting ad tracking on devices like your iPhone and iPad.
