Google also has a lot of category 4 data; although I don't have any Google accounts I am well aware that they track everything coming from my IP addresses, and from any of their cookies that I inadvertently allow through. All Google's posturing about 'review and manage your data' is meaningless to me in that regard. Why can't I ask them to delete everything associated with my IPv6 block, for example?
