According to the latest information, Facebook has been ordered to stop collecting data from users of Whatsapp in Germany, since according to the country, such an act constitutes a "violation of national data protection law".
Similarly, Johannes Caspar, commissioner for data protection in Germany, has also expressed concerns about the possibility that Facebook collects information from a wider range of users, including those listed in the contact list of WhatsApp that are not connected with Facebook.
According to the social network, with data obtained from WhatsApp can offer better suggestions of friends, most relevant ads, improve the fight against spam and even open the door for companies can contact directly with clients to any type of questions or problems.
It is also important to note that from WhatsApp have never asked clearly to your users permission to transfer data to Facebook, because how I told you, they just updated the terms and conditions of use of the application to offer the possibility of limiting such transfer.
You remember that when Facebook acquired WhatsApp, from the social network said that the privacy of users would not be compromised, but nevertheless, this promise blew up when last August WhatsApp introduced new terms and conditions under which specified data transfer with Facebook.
Finally, it is important to mention that Spain, the Spanish Data Protection Agency is still studying the changes introduced by WhatsApp in its terms and privacy.
