Below you will find a brief description of the names of the cookies that Mapp Intelligence can set in the browser, as well as the metrics and dimensions in the frontend that reflect the cookie information.

In general, you can recognize Mapp Intelligence cookies by their name beginning with wt (Pixel version 3-5) and wtstp (Smart Pixel).

Mapp Intelligence does not necessarily set all cookies mentioned in the list; some contain information about specific plugins, so these are only set if the corresponding plugin is in use.
