Third party cookies for analytics purpose

In order to provide our visitors with a better service, we measure the number of page views, the number of visits, the different actions performed by visitors on our site, the geo-location of our visitors and the number of times visitors return to our site. For this purpose, we use two web analytics software tools: Analyzer and Google Analytics.


Analyzer information

(AT Internet -

As far as AT Internet is concerned “cookies” are used to carry out relevant and detailed statistical research. The “cookie” is used in addition to the JavaScript tag, and thanks to the use of “cookies” it becomes possible to refine the analyses of JavaScript tags, and they also enable AT Internet customers to recognise visitors each time they visit their site. These “cookies” store information relating to only one AT Internet user ID, and under no circumstances is this information used to collect personal data on the visitors.

All of the results which are obtained are then compiled, and are completely anonymous. The results provide information on the navigation and behaviour of Internet users on the websites of AT Internet customers, information such as: the number of visitors, the number of visits, the number of page viewed and other information that is necessary for the effective measurement of Internet user interests. With these results it is then possible to improve the ergonomics and content of such websites.
