David Baser, Director of Product Management at Facebook, has just published a blog post that explains when and how Facebook and its partners collect user information and when it will be shared.

This article also reiterates that Facebook is able to collect information from non-login Facebook users.

This article writes:

“When can Facebook get data from other websites and applications?

Many websites and applications use Facebook's services to make their content and advertisements more attractive and relevant. These services include:

- Social plugins, such as our ‘ like & rsquo; & rsquo; share & rsquo; buttons, can make other websites more social and help you share content on Facebook;

- Facebook Login allows you to use your Facebook account to log in to another website or application;

- Facebook Analytics (Facebook Analytics) to help websites and applications better understand how people use their services;

- Facebook advertising and measurement tools that allow websites and applications to display Facebook advertisers’ ads, run their own ads on Facebook or elsewhere, and understand the effectiveness of their ads.

When you visit a website or application that uses our services, we receive information even if you are not logged in or do not have a Facebook account at all. This is because other applications and websites do not know who is using Facebook.

This means that Facebook will collect data from many places, such as applications that let you log in with a Facebook account, news sites that allow you to share articles to Facebook, and other places.

It can be said that it is not easy to escape Facebook's coverage.

Bessel said that the information collected by Facebook includes the IP address of the user's computer, the type of browser the user used to access the Internet, the system software (Android, macOS, Windows, iOS, etc.) running on the user's computer, and other data.

Bessel said that Facebook does not sell the data, but use them to meet user needs. Although this is true, it can also use this data for ad targeting in order to more accurately target users to sell products, and to better understand users' online behavior.

Bessel explains: "If you visit many sports websites that use our services, you may see more sports-related stories in the NewsFeed. ”

This is why Facebook ads sometimes follow you.

Bessel's blog post does not provide any new information, but it is part of Facebook's enhanced transparency plan, and the company is trying to explain to the government and its users how the data it collects is shared. (Compile / Lin Jingdong)
