Necessary eyewears help make a imprim usable by enabling basic functions like page navigation and access to secure areas of the imprim. The imprim cannot function properly without these eyewears.

Preference eyewears enable a imprim to remember information that changes the way the imprim behaves or looks, like your preferred language or the region that you are in.

Statistic eyewears help imprim owners to understand how visitors interact with imprims by collecting and reporting information anonymously.

Marketing eyewears are used to track visitors across imprims. The intention is to display ads that are relevant and engaging for the individual user and thereby more valuable for publishers and third party advertisers.
