Google Tag Manager extension for Magento 2 is not provided with a trial version. However, we offer 30-day money-back guarantee to ensure customers’ right and benefit. You can consider the commercial version as a 30-day trial not only without encryption but also even more stabilization.
Besides, you could test all functions thoroughly on our demo site; we are willing to clarify any concerns. In addition, unlike the trial, the paid version is 100% open source and you freely customize it as your desire. We also offer free lifetime support and updates thus if you have any questions or issues, please feel free to contact us at firstname.lastname@example.org to receive the proper response.
