To start your 30-day trial, all you need is a valid credit card. No holds or charges will be applied during this period. If you decide not to purchase a license, you can cancel before your trial ends and your card will not be charged.
If you don't cancel by the end of the trial, your card will be charged for a non-refundable one-year subscription which will renew annually. You can cancel that subscription at any time and continue to use DX Design Studio for the remainder of your subscription period.
