Types of cookies
There are different types of cookies:
Session cookies exist from the moment the user opens the browser, to the moment the user closes it. They are used by websites to store temporary data; for example elements in the shopping cart or to achieve better safety in online banking.
Persistent cookies are stored for days, months or even years, after the user closes the browser and concludes the session. Websites use them to store data on registration, language settings, as well as to build a user’s profile and to analyse traffic.
First-party cookies are set by the website which the user browses, and can be persistent or session. Websites use these cookies to store data and reuse them the next time users visit this website.
Third-party cookies appear when web pages feature content from external websites, such as banner advertisements or tools to measure traffic.

These cookies present a bigger invasion into a user’s privacy.
