Functionality cookies allow websites to remember the user’s website preferences and choices they make on the website including login details, geo-location, language, and enhanced content. This allows the website to provide personalized features for website users. Functionality cookies are used to enhance the performance of websites as without them certain functions of the website may not be available. Functional cookies are helping to provide services that a user requests. However, they are not vital for a website to run. They are anonymous and don’t track users' browsing activity across other websites. Examples of functionality cookies include web chat services, user preferences, geo-targeting, and language settings, and the ability to comment on a blog.
Functionality cookies can be either first-party, third-party, persistent, or session cookies. They are completely anonymous. Most cookie laws, including GDPR and CNIL, require an explicit Cookie Consent to use functionality cookies, which means that the Cookie Consent should involve an affirmative act.
