The visitor hash cookie contains the account ID and stores a unique hash. The visitor cookie is disabled, and the visitor is not tracked. If the visitor opts out or ignores the opt-in banner, the opt-in cookie value is set to false. If a visitor opts in, the value is set to true, and the visitor is cookied and tracked. If Tracking Opt-in preferences is enabled, the pi_opt_in cookie is set with a true or false value when the visitor opts in or out of tracking. This cookie is set for visitors by the Pardot tracking code. The visitor value is the visitor_id in your Pardot account.
