We have a licensing policy that could be considered rent-to-own.
Yes, you can have perpetual licenses for EmberGen, VectorayGen, and even our Suite! If you pay for 12 consecutive months without cancelling, for any license tier, your license will change over to a perpetual license. Staying subscribed keeps your perpetual license up to date. If you cancel your subscription, you are no longer able to update that perpetual license. For clarification, an annual license is considered 12 months of consecutive payment, or you can pay for 12 months straight via monthly payments.
If you pay for 11 consecutive months, and then cancel your subscription, you will not be granted a perpetual license. If you pay for 18 consecutive months, and then decide to cancel, your perpetual license will be updated to the latest build version that was available during this payment period on month 18.
You can switch from monthly to annual or annual to monthly at any time by contacting us.
