Google says the changes will make it easier for consumers to understand how it collects personal information, and allow the company to create more helpful and compelling services. Critics, including most of the country’s state attorneys general and a top regulator in Europe, argue that Google is trampling on people’s privacy rights in its relentless drive to sell more ads….
Google is combining more than 60 different privacy policies so it will be able to throw all the data it gathers about each of its logged-in users into personal dossiers. The information Google learns about you while you enter requests into its search engine can be culled to suggest videos to watch when you visit the company’s YouTube site.
So don’t log in….. I have found that Google tries to keep you logged in, so you may not even know you are, best to explicitly log in and out.
