[Margaret Pilkington]

As far as I know using google search engine will not be subject to the collection of personal data.
My understanding of the situation(and it could be I have got hold of the wrong end of the stick) is that if you have a google account and log in......or a Gmail account or a youtube account,google maps...or anyother google affiliated program, then that is when your preferences will be tracked, and data collected.

I use google as a search engine....and dogpile too....so I believe that nothing much will change(I don't have any google accounts that I log into).

To be honest, we are all subjected to so much scrutiny anyway CCTV camera's everywhere......if you have shoppers loyalty cards then you are already being scrutinised for your shopping habits.
We like to think we have privacy, but in reality, we don't have much.
