although Reciva state here
that they collect listening statistics data in anonymous form only, the radios massively upload data to their servers including the serial number of the specific device, its firmware version and additional data of an unknown purpose. This issue had already been raised quite a while ago here
, and the explanation of Reciva in their forums apparently was a reaction to that discussion.
This issue IMO is even more alarming than the Roku scenario I described here
, as Reciva do neither manufacture nor sell the radios. I doubt that all companies producing and/or selling Reciva based radios inform their customers about the upload function of the devices, so this data gets transferred to a third party without the consent of the customer and/or listener.
