These video games and quizzes are designed to tempt customers in however they’re typically only a store entrance for mass knowledge assortment – and one which Fb’s phrases and circumstances permit.

Privateness advocates Digital Frontier Basis mentioned the best way these quizzes collected knowledge mirrored “how Fb’s phrases of service and API had been structured on the time”.

Fb has modified its phrases and circumstances to chop down on the data that third events can accumulate, particularly stopping them from accessing knowledge about customers’ associates.

It isn’t but clear precisely what data the agency acquired maintain of – that is now topic to an investigation by the UK data protection authority, the ICO.

What can customers do to guard their data?

• Unclick each class you do not need the app to entry, which incorporates bio, birthday, household, non secular views, in case you are on-line, posts in your timeline, actions and pursuits

There are some others items of recommendation too.

“By no means click on on a ‘like’ button on a product service web page and if you wish to play these video games and quizzes, do not log in by means of Fb however go on to the positioning,” mentioned Paul Bernal, a lecturer in Info Expertise, Mental Property and Media Regulation within the College of East Anglia College of Regulation.

“Utilizing Fb Login is simple however doing so, grants the app’s developer entry to a variety of data from their Fb profiles,” he added.

How else are you able to shield your Fb knowledge?

There actually is just one manner to verify your knowledge stays solely personal, thinks Dr Bernal. “Depart Fb.”

“The inducement Fb must shield individuals extra will solely come if individuals begin leaving. At present it has little or no incentive to alter,” he advised the BBC.

It appears he’s not alone in his name – the hashtag #DeleteFacebook is now trending on Twitter within the wake of the Cambridge Analytica scandal.

However Dr Bernal acknowledges that it’s unlikely many will give up – particularly those that see Fb as “a part of the infrastructure of their lives”.

Can you discover out what knowledge on you is saved?

Beneath present knowledge safety guidelines, customers could make a Topic Entry Request to particular person companies to learn the way a lot data they’ve on them.

When Austrian privateness advocate Max Schrems made such a request to Fb in 2011, he was given a CD with 1,200 recordsdata saved on it.

He discovered that the social community saved data of all of the IP addresses of machines he used to entry the positioning, a full historical past of messages and chats, his location and even objects that he thought he had deleted, corresponding to messages, standing updates and wall posts.

However in a world the place Fb data is shared extra broadly with third events, making such a request will get more durable.

As Dr Bernal says: “How do you ask on your knowledge when you do not know who to ask?”

That’s prone to change this summer time with the introduction in Europe of the Basic Information Safety Regulation (GDPR), which goals to make it far simpler for customers to take again management of their knowledge.

The specter of huge fines for companies that don’t adjust to such requests might make it extra probably that they may share this data, which have to be given to customers “in a transparent and readable kind”.

How lengthy is knowledge saved?

Information safety legal guidelines in Europe counsel that companies ought to solely maintain consumer knowledge “so long as mandatory” however the interpretation of this may be very versatile.

In Fb’s case, because of this so long as the individual posting one thing doesn’t delete it, it’s going to stay on-line indefinitely.

Are you able to delete historic knowledge?

Customers can delete their accounts, which in concept will “kill” all their previous posts however Fb encourages those that want to take a break from the social community merely to deactivate them, in case they want to return.

And it have to be remembered that lots of details about you’ll stay on the platform, from the posts of your mates.

One of many greatest adjustments of GDPR would be the proper for individuals to be forgotten and, underneath these adjustments it ought to, in concept, be a lot simpler to wipe your social community or different on-line historical past from existence.
