Yes! Please choose the “7-day free trial” on the pricing page or install the free version of the plugin and go to the Tag Groups settings. On the “Premium” page you will find a link where you can start a trial.
The trial is free, but you need to cancel it before the 7-day period has ended if you decide that you don’t want to continue using it. If you don’t cancel, the payment for the chosen plan will be made.
