Here's how Facebook tracks you even when you're logged out

Here's how Facebook tracks you even when you're logged out

The company yesterday published a blogpost, where its product manager David Baser said that Facebook collects data about web users who aren't even logged into Facebook. "We require websites and apps who use our tools to tell you they're collecting and sharing your information with us, and to get your permission to do so", a Facebook post reads.

A new public filing shows Facebook significantly increased the amount it spent on keeping Zuckerberg safe in 2017, upping such expenses more than 50% from the $5.8 million it spent in 2016. If they do, we'll show them ads from the same advertisers that are targeting them on Facebook. Zuckerberg did not respond. On Friday Facebook said it had no plans to build such a tool.

In the company's filing, it said the "overall security program" was authorized "because of the high visibility of our company" and was created to address "safety concerns due to specific threats to his safety" that include security systems for Zuckerberg's personal residences, annual costs of security personnel and private aircraft. "It's not clear what Facebook is doing with that information", said Chris Calabrese, vice president for policy at the Center for Democracy & Technology, a Washington advocacy group.

The company also said it will reward people with first-hand knowledge and proof of cases where a Facebook platform app collects and transfers people's data to another party to be sold, stolen or used for scams or political influence. The company has now tried to clarify on questions how it collects data even when people are actually logged out of the website or the app. He acknowledged that Facebook should not have trusted Cambridge Analytica's assurance that it will stop using user's personal information it collected. So when a website uses one of our services, your browser sends the same kinds of information to Facebook as the website receives.

"One of those being that everyone globally on their Facebook page will see an alert leading them to the apps setting where they can review the apps they have allowed to access their data".

He also claimed that the information received from websites and apps was also used to help protect the security of Facebook.

The blog post concluded by going over what controls users have over their data.

Advocates and lawmakers say they are singling out Facebook because of its size, rivaled outside China only by Alphabet Inc's (GOOGL.O) Google, and because they allege Zuckerberg was not forthcoming about the extent and reasons for the tracking.

Facebook declined to comment on why Zuckerberg referred to security only. Facebook said on Friday that it does not do so.

Facebook said in its statement on Friday, "Our products and services comply with applicable law and will comply with GDPR".

As Baser noted, the social network is not the only website that does this. We don't sell people's data.
