Facebook admits tracking users and non-users off-site

Facebook has released more information on the social media platform's tracking of users off-site, after CEO Mark Zuckerberg failed to answer questions about the process from US politicians and as the company prepares to fight a lawsuit over facial recognition in California. In a blog post, Facebook product management director David Baser wrote that the company tracks users and non-users across websites and apps for three main reasons: providing services directly, securing the company's own site, and "improving our products and services". "When you visit a site or app that uses our services, we receive information even if you're logged out or don't have a Facebook account. This is because other apps and sites don't know who is using Facebook," Baser wrote. "Whether it's information from apps and websites, or information you share with other people on Facebook, we want to put you in control -- and be transparent about what information Facebook has and how it is used."
