Cookies What is a cookie? A cookie is a small text file that is stored on your computer or portable device when you visit a website. A first-party cookie is a cookie set by the website you are visiting. Only this site can read it. In addition, the website may use external services that also set their own cookies, called third-party cookies. A persistent cookie is a cookie that is stored on your computer and is not automatically deleted when you close your browser, unlike a session cookie that is deleted when you close your browser. Cookies make the website remember your settings (username, selected language, etc.) for a while. Thus, when you browse different pages of the site in one visit, you do not have to specify the settings again. Cookies may also be used to create anonymous statistics about your browsing experience on our websites. How do we use cookies? We use three types of first-party cookies to: save visitors' preferences; ensure the functioning of our websites; collect analytical data (visitor statistics). Visitor settings These cookies are set by us and only we can read them. These cookies remember: whether you have accepted (or rejected) the website's cookie policy; or you have already answered our questions in the survey pop-up window about whether the content of the site was useful (so that this window will not pop up again).
