If your software is useful, and if you're a small company / one man show, I will pay for it, even if I barely have any money, or if I have lots of money. But the key for me is not having a really useless and stupid and intrusive anti-piracy mechanism, as that usually makes me go away from that software. Example of that are games like Kerbal Space Program that are useful, fun, and have no anti-piracy mechanism. I paid for it. And the other example is pretty much any huge game like GTA V, that I bought my brother as a gift but it often stops working and has to be reinstalled because it detects some tampering or something like that, it's from Steam BTW. I'd also recommend that you DON'T offload processing to a server, as that will prevent people with spotty Internet (like me) or those in special circumstances / behind firewalls from using it properly, and also has data security issues.
