I am creeped out by a google phenomenon that I have noticed a few times and I don't know quite how far it goes.
I was at a play the other night with my fiance and mother in law. We saw a poster for another play on tour that I was interested in. I searched on my phone for tickets in Birmingham but it was sold out. Then I searched for tickets in nearby Wolverhampton, but I was mistaken, the tour was never going to Wolverhampton. At that point I had devoted too much time to it so I gave up.
Yesterday I was at my mother in law's house and she asked if it was worth looking up that play again. As she started typing google auto completed the search with "Wolverhampton" and it appeared in a purple font as if it were part of her search history.
In the past I have put this to coincidence but the fact that it completed to a town that had no relevance to the play makes me think that it was my search that it's referring to.
I have logged onto my gmail on her computer once before to print something out, probably 8 months ago but I made sure I'd logged off after I was done.
I am worried that she may have access to searches I make and vice versa! I frequently see strange auto-complete searches coming to me but I put that down to google targeting "relevant" searches to me. What can I do to stop this?
