uFab offers a 30-day free trial with full access to all features so that you have time to review and test out the tool in its entirety before you purchase. Therefore, all sales are final, and no refunds are available after purchase.
If you want to change your subscription plan, you can do so by going into your account, and edit your current subscription. The changes will be applied at the end of the current term (month or year, respectively), and your invoice will be updated and charged on the next billing date.
After the 30-day full access free trial, if you do not purchase a Monthly or Yearly subscription, your account will be disabled.
