Why VWO Use Cookies?
VWO uses persistent visitor-level and local storage cookies to understand visitor’s behavior and track visitor journeys on the website to deliver the best experience. The cookies track the variation a visitor views and help serve the same variation to the visitor consistently, track their goals, and determine whether they are part of a campaign, and so on.
VWO uses different cookies, each storing a different set of data. The cookies do not interfere with the loading or functioning of the website.
It helps distinguish one visitor from another. This means no individual or consumer can be tracked or identified by VWO.
Let’s have a look at the different cookies stored by VWO.
