KXStudio is and always will be a free and open-source project to everyone.
Donations help ensure that developers have the needed enthusiasm and motivation to keep working on the project.
Just because we're open-source doesn't mean we're allergic to money. ;)

The KXStudio project is no longer taking donations.

In German law donations count as income and thus have to be taxed.
It came to the point where it was more expensive for the project to have them rather than not.
As such, donations have been taken down for now.
They might come back at a later time, when the (single) KXStudio developer relocates to another country.

Thanks for understanding.
