You may have heard in the news that Google has announced a change in its terms and conditions. It says that it can now do more and more with your internet use data. It does not say that you will be notified of who gets access to your data. And no, you won’t get a cut of the money if your internet usage data is sold to a 3rd party.
The context your data is used or presented is not known so you have to “trust” them on this one.
Then, I heard about StartPage.com this is a very cool concept of a search engine that strips your personal information from your queries so that Google is not watching and recording everything you do.
