The German parliament has been warned by its official eggheads that Amazon's Alexa digital assistant may not be legal – because it stores voice recordings and overhears things it is not supposed to.

The Scientific Services of the German Bundestag was asked to take a look at how Alexa works and how the device fits within the country's current privacy laws. It concluded, in a report made public this week, that there is ample evidence that the Amazon device routinely records things it is not supposed to and that the internet giant stores those recordings far longer than it needs to. That raises some serious legal questions, the dossier notes.
