Types of Cookies and Purposes of Use

  • Session Cookies: These are temporary cookies that are used during visitors' visits to the website and deleted after the browser is closed. The main purpose of using this type of cookie is to ensure that the website functions properly during your visit.
  • Persistent Cookies: These are types of cookies used to increase the functionality of the website and to provide a faster and better service.

This type of cookie is used to remember visitors' preferences and is stored on visitors' devices by means of browsers.

Some types of persistent cookies may be used to offer personalized recommendations to visitors, taking into account matters such as the purpose for which the website is used. By means of persistent cookies, when the website is visited again with the same device, it is checked whether there is a cookie created by the website on the visitor's device and, if so, it is understood that the website has been visited before, and the content to be delivered to visitors is determined accordingly.

In this context, Facebook Pixel, Google Analytics, Yandex Metrika, LinkedIn and the Add This tools, which are added only on article pages for sharing, are used for measurement and analysis. We recommend that you also review the privacy and cookie policies of these tools. Information such as the language of your internet browser, your time zone, the time spent on our pages and search engine optimization information is obtained by these tools, and information about visits to our website is shared with us anonymously and cumulatively (such as how many visitors come from which country) through the tools we use. The tools we use do not share with us the personal data they process. The cookies created by these measurement tools have no effect on the functioning of the site

The information collected by these cookies may include confidential data that can identify you, such as your username or profile picture. Not allowing the use of this type of cookie may result in a feature specific to you not being available and prevents your preferences from being remembered.
