You must be very careful what you search for using Google. Google keeps records, sells information.
Google is that ‘Big Brother is Watching’ from 1984. The motto; “Do No Evil” was selected because that is exactly what they planned to do.
Even if you are looking up a term for definition; if it is on the ‘watch list’ your I.P. and other information will be turned over to Homeland Security or other government agencies.
This is not paranoia, a joke… this is real.
There are other Search Engines besides Google. Other sites, i.e. duckduckgo.com, keeps no record of what you are looking for.
You may want to use other search engines to safeguard your privacy.
