Donation duration


I used tu use Fritzing from time to time and I just saw that we need to make a donation to download the binaries.

This is not a problem for me, as it’s agreat project but I’d like to understand how it works :
It is a:

  • one time donation every time I want to download Fritzing
  • lifetime donation for every future versions ?
  • limited time donation (every new version for next n year(s)

Thank for your help on that point.
