The Federal Minister of Justice, Heiko Maas, last week presented Guidelines for the introduction of a storage requirement and maximum retention period for traffic data. These guidelines outline plans to require providers of telecommunication services to retain telephone numbers, location data and IP addresses for four to ten weeks. Emails, however, will be exempt. Once the retention period has expired, the data shall be deleted. Creating personality and movement profiles will be forbidden. Maas maintained that the guidelines respect the standards set by the European Court of Justice and the German Federal Constitutional Court. The German Federal Privacy Officer, Andrea Voßhoff, however, expressed doubts about this.
