During the wizard in our plugin we ask you several questions regarding the cookies you’re using. One of those cookies we are asking are functional cookies. In this article we will explain what these are and why they are used.

Functional cookies

Functional cookies are cookies that fall outside the scope of the cookie law. There is no need to request permission for this kind of cookies, nor is there any need to describe them in your cookie policy (although we think that is a good idea).
Functional cookies do not have to be mentioned because there shouldn’t be any reason to reject cookies of this kind. Functional cookies are strictly necessary to be able to offer the visitors of your website the best experience. For instance, Google Analytics could be a functional cookie, as it’s being used to optimize the website based on visitors’ behavior.
Notice the word ‘could’ in the previous sentence? That’s because Google Analytics is not always a functional cookie.

Examples of functional cookies

Other examples of functional cookies are:

  • a shopping cart
  • a login cookie
  • a language cookie
  • session ID cookies


There are some restrictions regarding functional cookies. Functional cookies can never collect any personal data as giving away personal data on a website shouldn’t be necessary to perform.
