Google’s ad tracking is as creepy as Facebook's. Here’s how to disable it

Google in June deleted a clause in its privacy settings that said it would not combine cookie information with personal information without consent

Since Google changed the way it tracks its users across the internet in June 2016, users' personally identifiable information from Gmail, YouTube and other accounts has been merged with their browsing records from across the web.

An analysis of the changes conducted by Propublica details how the company had previously pledged to keep these two data sets separate to protect individuals' privacy, but updated its privacy settings in June to delete a clause that said "we will not combine DoubleClick cookie information with personally identifiable information unless we have your opt-in consent".
