Due to both work and interests I have been very active on social media for many years. All of them. Facebook, Twitter, Instagram etc, but also the old ones that are no longer in business. Basically, if there was a new service I signed up on it and tried it out. Often it was to figure out what the service was all about and thus also to figure out how it worked.
Well timed for my latest series of privacy related things I received an e-mail the other day, from Google. They wanted to let me know that they know exactly where I am and where I have been, regardless of if I'm using their Chrome browser or not. Apparently I have settings and apps in my iPhone (which obviously is made by Apple, not Google) that automatically report this stuff back to Google.
