A lot of places track where you go on the internet one of them is Facebook. If you want to opt out or just want to find out how many are tracking you go here.
Hi there Janet
Sometimes when you don't have a "cookie" on your computer for that site and you have signed up there you have to log in every time you go there.
It won't keep you from going to those sites it is just that some cookies will report back to a site where you went after you left their site or how many times you go to a certain site.....it isn't like they have your name and address but some people don't feel comfortable being tracked like that.
Remember years ago when you would sign up for a give away at a store, you filled out your name address and phone? Then you thought it was funny you were getting all this (snail) mail? Or phone calls wanting you to buy insurance or siding?
They use some of this information to see how well their site is doing and what brings you to their site...most of the time I would say there is nothing to worry about........just what you feel comfortable with.....
