Try to log-off curezone, and try to surf the website.
You will see that many pages become unavailable, like a page used for posting new messages, or inbox, or private messages etc.
Google can not access your own private messages, unless you personally give google your username and password.
And, even in that case, Google could only access your inbox and your Sent box, but not mine or his.
There are public pages on CureZone (like forums and blogs), and there are private pages on CureZone (like private messages).
The only way to access private pages: you have to log-on.
Google can not log on to your own account, or to my account. For that, usernames and passwords are needed, and Google has no access to our usernames and passwords.
But, Google is indeed a very "big brother", even if you never use Google search engine.
There are millions of websites using a free service called "Google Analytics".
There are millions of websites serving google ads Adsense.
Through Google Analytics and through Google Adsense, google can follow your surfing habits from one website to another, without you ever being aware that you are watched!
Even if just every second website you wisit have Google Analytics or Google Adsense, google can compose a detail list of all websites you have ever visited.
Google actually knows more about you then you yourself!
You have probably forgotten all the websites you visited since 2005. Google has not forgotten! Google knows everything about you, even your dreams!
Google can read your mind based on your surfing habits, and is able to serve you with Google advertisements
tailored just for your own eyes! The google ads and banners you see when surfing the web may be tailored just for you!
