"Passive Information Collection

As you navigate through this site, certain anonymous information can be passively collected (that is, gathered without your actively providing the information) using various technologies, such as cookies*, clicktags, beacons and other navigational data collection (such as server logs). Your internet browser automatically transmits to this site some of this anonymous information, such as the url of the website you just came from and the IP address and the browser version your computer is currently using.
This helps us analyse data about our site traffic, so we can improve Gransnet and tailor it more to our members' needs. All information is anonymous and only used for operational purposes.

*A cookie is a small file which "asks permission" to be placed on your computer's hard drive. Once you agree, the file is added and the cookie helps analyse web traffic or lets you know when you visit a particular site. Cookies allow web applications to respond to you as an individual. A cookie in no way gives us access to your computer or any information about you, other than the data you choose to share with us. You can choose to accept or decline cookies.

Hokydoky.

What this means, is that, like all other sites, information is sent when you click on pages. It's usually only that someone's clicked on that page, known as a 'page hit', and it's used to see how many people have seen that page. All of the information is anonymous and this happens on every site you go onto, not just Gransnet. It works the same way with adverts etc.
