If you're looking for a weekend activity even more horrifying than doing your taxes, considering looking at every piece of data Facebook keeps on you.
The massive amount of data Facebook collects on its users is not technically sold to third parties.
On Monday, Facebook revealed that about 271,469 data belonging to Nigerians on Facebook, whose friends would have installed the "This is Your Digital Life" app, were exposed to the Cambridge Analytica data breach.
Facebook says many other websites and apps use its services to make ads more relevant, including social plugins (the floating Like/Share buttons); using Facebook as a login to their sites/apps; Facebook Analytics; and the company's ads/measurement tools.
Facebook says it can match that data to a Facebook profile, if the person has one.
Facebook is like the proverbial rabbit hole: easy to get lost in there, hard to find your way out.
Following the US Congressional hearing last week where CEO Mark Zuckerberg was grilled about Facebook's data gathering and sharing practices, the social media network is trying to limit the damage by explaining how its various data collection policies work.
'We do that for a number of reasons including security and measuring ads to make sure that the ad experiences are most effective, which people can of-course opt out of.
Hurricane names Harvey, Irma, Maria and Nate being retired
Since 1953, 86 hurricanes and tropical storms have caused enough devastation to be removed from the Atlantic lists. Hurricane Nate hit Central America and the Gulf Coast of the USA , eventually becoming a Category 1 hurricane.
Facebook allows advertisers to target users with adverts specifically based on personal data it holds.
The blog post also reviews the types of controls people with Facebook accounts have over their data.
Facebook had also launched a "Data Abuse Bounty" programme to reward people who report any misuse of data by app developers.
Privacy concerns have swamped Facebook since it acknowledged last month that information about millions of users wrongly ended up in the hands of political consultancy Cambridge Analytica, a firm that has counted US President Donald Trump's 2016 electoral campaign among its clients.
The "tag suggestions" feature, involves Facebook running facial recognition tech on uploaded photos to match them with other users automatically.
A federal judge ruled Monday that millions of the social network's users can proceed as a group with claims that its photo-scanning technology violated an IL law by gathering and storing biometric data without their consent.
The feature was turned off in the European Union shortly after it launched, and Facebook committed in 2012 to delete all face templates by October that year, as part of a wide-ranging agreement with the Irish data protection commissioner. Damages could potentially run into the billions of dollars-a fact that wasn't lost on the judge, who was unsympathetic to Facebook's arguments for limiting its legal exposure.
The case is In re Facebook Biometric Information Privacy Litigation, 15-cv-03747, U.S. District Court, Northern District of California (San Francisco). "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.
