Facebook collects data from everyone, even if you are not logged in or not using Facebook

Facebook has admitted they collect data from Facebook users, but what about those who don't use Facebook?

Most of Facebook's data is shared by users. Users can control data, reference or delete them whenever they want. If a Facebook account is deleted, most of the data will disappear from Facebook's server within 90 days. This information is true but they are not all. On the second day of the US Congress hearing, Mark Zuckerberg revealed some information about their gathering of users' data even when they were not using Facebook.

Senator Ben Lujan asked Zuckerberg "The information has been acknowledged that you have collected data from people who do not use Facebook. So people without Facebook accounts can choose to not participate in the crawl behavior. Does Facebook's involuntary data or not? "

To this question, Zuckerberg answered that anyone can opt out of collecting data for advertising whether they use Facebook's service or not. But Facebook needs to know someone who is continuously accessing the service to prevent users from being drowned out.

Users can download their Facebook data but those who do not use Facebook will not be able to access this database. Furthermore, even the download tool that Facebook provides users with no data that Facebook collects and uses from other sources such as its Facebook Pixel analytics tool or the location taken from the user's phone.

The most obvious proof for this is Facebook's 'People You Can Know' service. Although you haven't registered for Facebook yet, you still appear in the contact list of people who are using Facebook. When users connect their account email or messaging data to Facebook, users without Facebook accounts will appear. Facebook collects data from non-Facebook users and binds it to what is called a shadow profile, a trusted information bank that can be saved and not deleted.
