All of the software published in this site is free, and most of it open source. I have a commitment to keep it free AND free of ads, so it generates absolutely no money.
So if you really like any of my software and feel generous, feel free to send me a buck or two.
I'm also committed not to nag people and not to extort them in any way, so donators won't get any benefit nor unlock any extra feature (other than my gratitude).
