c-referrer also acts as a Functionality Cookie, when either the referring page or the landing page information makes these users eligible for special referral discounts on paid plans.
In all cases, this is a first-party cookie and we only save and use information in this cookie after users sign up to use Cognito Forms. We do not use this cookie for targeted advertising and only use this information to improve our product and enhance the experience for our customers.
