Google announces the changes on its official blog, where they explain that they’ve had lots and lots of different privacy policies before, around 70, and now they’re just going to smush a bunch together to make it easier for the user. Oh, but also easier for them to collect info on what you’re doing.
As CNET puts it, before there were only implicit rights for Google to combine your information, and now they want it to be explicitly written out that it’s fine for them to do so.
Starting March 1, your activities and data while signed in and using Google products will be used by them to create a “simpler, more intuitive” experience. This means if you’ve looked at videos of funny kids after going to the dentist on YouTube, when you search on Google next for “kid dentist” it will bring up those videos instead of thinking you want to find a dentist for your kid.
You agree to the new policy simply by continuing to use Google products after the change takes place, according to the FAQ.
Useful, maybe, but also, kind of creepy. Where does it stop?
