That data, downloaded over years of Facebook users freely giving apps such as games and personality quizzes access to their information, is largely still stored outside of Facebook's grasp by the private individuals and companies who built those applications. The spokesperson said the company is focusing on mobile because that's where most of its users use the platform, and where the settings were most dispersed.
The development comes at a time when Facebook is facing heat from all quarters over the leak of personal and other data of some 50 million users to political consulting firm Cambridge Analytica.
Facebook is updating its privacy settings to make it easier for you to control what you share - with the social network and connected apps - and tools to delete the data it's collected on you. Here you'll be able to activate two-factor authentication, control you personal information, control which ads you see, and manage who sees your posts and profile information.
"We'll also update our data policy to better spell out what data we collect and how we use it".
"The recent news about Facebook's alleged mismanagement of users' data has solidified our decision to suspend our activity on the platform at this time", said a statement from Playboy.
He described the questions that MPs have as of "fundamental importance to Facebook users as well as to our inquiry" - and said the seriousness of the allegations meant it was "appropriate" for Mr Zuckerberg to appear in person or via video link.
The Cambridge Analytica scandal is still fresh and it seems as though Facebook is introducing these changes to regain the public's trust, as pointed out by The Next Web. She pointed out that in 2010, Zuckerberg said in the Washington Post that Facebook users needed simpler controls over their privacy and had promised then that Facebook would "add privacy controls that are much simpler to use".
The company has faced a global outcry after a whistleblower revealed, on March 17, that data from 50 million users was improperly harvested to target US and British voters in close-run elections.
The Ministry of Electronics & Information Technology has asked Facebook to specify whether the data has been used to manipulate the Indian electoral process. The company's market value has plunged more than $90 billion since the scandal broke.
