Cookies are small text files sent by most of the websites we visit. They are saved on the device we use when browsing websites, e.g. on computer, laptop, phone, smartphone and any other devices with installed memory that allow you to browse the Internet.


Cookies contain information needed for the proper functioning of websites, written in the form of series of letters and numbers. First of all, they are necessary for tasks that require authorization, e.g. logging into an e-mail account, online store, or a social networking site.


The most important information about "cookies".


They are not intended to identify users,  nor are they used to determine the identity of users.

Their main uses and behaviors include:

  • identification of the data of the computer and its browser used for browsing websites, e.g. whether a given computer has already visited a particular website;
  • data obtained in cookies is not combined with personal data obtained in other circumstances, eg as a result of registration on the website or setting up an e-mail;
  • do not change the way devices (computers, laptops, etc.) work and are not harmful to them in any way;
  • do not change the configurations used for browsing devices and the software installed in them;
  • thanks to appropriate cookie security, only the website that created them can read the information contained therein;
  • adjust the displayed page to our preferences thanks to the analysis of our behavior on the Internet.


The use of "cookies".


The idea for which "cookies" began to be used was to optimize the use of websites by giving it an individual character tailored to a given user. Thanks to this, the text, photos or surveys (of course, advertisements) appearing on the website can potentially interest us, saving us from having to wade through uninteresting content.



  • remember our visits to the website, our expectations for it, such as language, color, content layout, etc .;
  • enable the operation of accounts on websites;
  • prevent the need to log into every subpage of the website - which would be extremely irritating;
  • enable online stores to offer us articles that may be of interest to us based on the analysis of what we usually choose;
  • allow online stores to store selected products in the shopping basket;
  • remember the surveys and advertisements presented to us, so that we are not constantly harassed with the same content;
  • enable the presentation of advertisements in such a way that we are potentially interested in them, by taking into account our interests, place of residence and other characteristics, thanks to which advertising is more effective, and advertisers are more willing to buy advertising space on a given website, which has a positive aspect for us - a lot of websites can be used for free because they live off advertising;
  • make it easier to keep anonymous popularity statistics of websites, incl. it allows potential advertisers to find out within the range of the advertised by them.


To sum it up, the use of "cookies" allows publishers of websites to develop them further - a website that does not take into account the market demand may quickly become unpopular or even dead. The use of new solutions combined with the analysis of the obtained information helps to create an environment friendly to Internet users, adapted to them as much as possible. After all, it is in the interest of all concerned parties - not only the owners and advertisers. Cookies also provide the opportunity to constantly monitor the changes introduced, showing their accuracy or pointlessness.
