Advertising cookies
Advertising cookies allow targeted advertising to be displayed on sites on the Internet that are participating in this advertising system. Targeted advertising is displayed based on the behavior of an anonymous user or group of users on the website, by identifying their browser as described above. For example, if you were looking for a cheap mobile phone call last time, the next time you visit, you will probably be offered or reminded of this service.
Other websites that are involved in this advertising system include some social networking sites.
Other types of cookies may still be used, for example, for the correct functioning of our services (e.g. forms), in questionnaire research or for testing parts of the website and its functionality.
All of these help us to improve the quality of our services.
