For a sneak peak of the kind of data you can expect take a look here [1] (German newspaper, but in English).

Background story: Malte Spitz, a Green Party member, sued to get all data collected and retained (according to a law which has been overturned since) by his carrier. Die ZEIT/OpenDataCity cross-referenced the data with publicly available information from his Twitter and party website and compiled it all into one visualization.

Unfortunately, they seem to have stopped paying for the Google Maps integration, but you should still be able to follow along just fine.

This is interesting, if that's indeed the case then I'll publish my findings and encourage people to 1) fill similar requests, 2) fill requests for data deletion and ceasing of further collection. Hopefully eventually we'll get an option to opt-out via the web, like on http://myactivity.google.com/

Also, EU readers: why not ask your own provider today?

Apart from location I'm still concerned about actual data transferred via those networks (calls, text and data).
