When WhatsApp, the internet messaging app, announced last month that it was starting to share some of its usersâ online information with Facebook, its parent company, many users expressed anger that their digital privacy could be put at risk.
Now, a German regulator thinks so, too.
The city of Hamburgâs data protection commissioner ordered Facebook on Tuesday to stop collecting and storing data on WhatsApp users in Germany, the first time a privacy watchdog has waded into the debate. The regulator, which has authority over Facebookâs activities across Germany, also called on the social networking giant to delete all information already forwarded from WhatsApp on the internet messengerâs roughly 35 million German users.
âIt has to be their decision, whether they want to connect their account with Facebook,â Johannes Caspar, the Hamburg data protection commissioner, said in a statement. âTherefore, Facebook has to ask for their permission in advance. This has not happened.â
A representative for Facebook was not immediately available for comment.
The privacy pushback comes as WhatsApp, which was acquired by Facebook in 2014 for $ 19 billion, is trying to forge closer links with the social network and to look for new ways to generate revenue from its more than one billion users worldwide.
All the talk about data privacy can get caught up in political wrangling. But the different approaches have practical consequences for people, too.
As part of its proposed overhaul, WhatsApp said it would start disclosing the phone numbers and analytics data of its users to Facebook. WhatsApp also has plans to allow businesses to contact customers directly through its platform. A similar strategy was already being tested on Facebook Messenger, a separate messaging service Facebook owns.
While WhatsApp has framed the changes as a way to give users a better experience, not everyone is convinced. A day after the announcement, the British privacy regulator said that it was looking into the changes.
More than any other region, Europe has pushed back against American technology giantsâ use of peopleâs digital information, routinely forcing companies like Google and Facebook to change their policies after they breached the European Unionâs tough data protection rules.
In its decision on Tuesday, which would affect only WhatsApp users in Germany, the Hamburg regulator said that neither the internet messenger nor Facebook had received individualsâ permission to share the information and had potentially misled people over how their data would be used in the future.
The watchdog added that millions of people whose contact details had been uploaded to WhatsApp could now have that information shared with Facebook against their will, a possibility that infringed German law.
âFacebookâs answer, that this has merely not been done for the time being, is cause for concern that the gravity of the data protection breachâ will have a more severe impact, Mr. Caspar said.
