In order for this website to work, sometimes we save on your device small data files called cookies. Most websites also use this method.




Cookies are small text files that are stored on your computer or mobile device when you visit a website. They allow the website to memorize your actions and preferences (e.g. username, language, letter size and other display settings) for a definite period of time, so that you don’t need to enter them every time you visit the website or pass from one website to another website.




A number of our pages use cookies to memorize:

  • Your display settings, such as colour contrast settings or letter size;
  • Information about whether or not you have already filled in a research on the website content usefulness, so that you are not asked again;
  • Information on whether or not you have agreed to the use of the website cookies.

Besides, some videos on our pages also use cookies to collect anonymous statistics about how you have reached the respective website and about the videos you have watched.

Enabling cookies is not an absolute must for the website to work. However, it will contribute to its better use. You may delete or block the cookies, and if you do it then some website functions may not operate as required.

Cookies-related information is not used to establish your identity, but data samples are entirely under our control. Cookies are not used for purposes other than those specified herein.



All contemporary browsers allow you to change the cookies settings. Usually you can find these settings in the "options" or "preferences" menu of your browser. In order for you to be aware of those settings, the following links could be of your use or you may use the "Help" button from the menus of your browser for further details:
