Cookies are short text files created by a web server and stored on a computer through a browser. If you return to the same website, the browser sends the stored file back, and the server then retrieves all the information it previously stored about you.

How and why are cookies used?

Cookies are essential for functional web analytics. Visitor statistics and other measurement systems work on the principle of cookies, storing visitor identifiers, sources of visit, time, etc., in a cookie. The collected data is then accessed and supplemented on subsequent pages, allowing the system to “track” the user. These small text files are also used to store the state of being logged in on a given page (to website administration, e-commerce, social networks, etc.). This type of cookie is called an authentication cookie. Without it, the server wouldn’t recognize that a user’s verification and login to a particular website has already occurred and would request it again for every subsequent page visit.

What are the types of cookies?

First-party cookie – A small text cookie is stored using a script running on a given domain. Such cookies are generally considered safer. They pass through firewalls better and adhere to stricter browser security rules. This type of cookie is used, for example, by Google Analytics (in its default setting). Third-party cookie – A cookie is stored using a script pulled from a different domain. Therefore, the same cookie can be accessed in various places on the internet, allowing a user to be tracked across different domains.

Why “cookie”?

As you’ve likely guessed, “cookie” means biscuit in English. The name is derived from the Anglo-Saxon custom of offering a biscuit to visitors to create a homely and pleasant atmosphere. What types of cookies do we use? Cookies can be divided into two types based on their duration. One type is temporary (session cookie), stored in the browser only for the duration of the session. The other is a long-term (persistent cookie), which remains stored for an extended period or until manually removed from the browser. In terms of their function, cookies can be divided into several types. The first type is remarketing cookies, used for personalizing our advertisements’ content and targeting. Another type is analytical cookies, which help us understand how our website is used by users. Essential cookies are vital for the website’s basic functionality. We also use conversion cookies to analyze the performance of conversion channels. The last type we use is tracking cookies (tracking), which, combined with conversion cookies, help analyze the performance of various conversion channels. Some cookies may collect information used by third parties. These cookies directly support our advertising activities (PPC systems like AdWords, Sklik, etc.). Thanks to these cookies, we can customize the display of banners or ads on your viewed web pages. However, these data don’t allow us to identify you.
