Referrer Source Free or Paid?

On the If>So website, under plans, it lists the Conditions that are included for both free and paid versions. I downloaded the plugin planning to use the the Referrer Source Condition expecting this was included in the free version along with A/B testing. After installing it, it’s asking me to get a license in order to get those features and start a 30 day free trial. Do I need to pay in order to get those features? Or once the free trial is up will those two features still work? Thanks.
