Donationware is a licensing model that supplies fully operational unrestricted software to the user and requests a donation be paid to the developer (in this case PROSPECTUM).

We ask a relatively low minimum donation (typically around 30-40% of what the virtual organ is worth) that you are required to pay in order to obtain a license for the respective virtual organ.

In addition, you are kindly invited to make an additional voluntary payment according to your own discretion and financial scope.
