Our AFL UTM Tracker plugin uses cookies to store data about the visitor visits. Since our plugin is not a full analytics server, we use quite a number of cookies to store various data so that your WordPress server does not need to fill the database of every visitors. We only read the data from the cookies only when a conversion happens or when Active Attribution is enabled.
Here’s the list of cookies which our AFL UTM Tracker plugin generates:
