Hi I am new here...

I am about to complete my first PyQt desktop software for commercial release.

I have never released a desktop software, so this is a new adventure for me.
My main concern is how to protect my software from being "cracked", meaning stolen and redistributed.

I looked for some guidelines online, but surprisingly, I haven't found anything.

I am trying to figure out some ways to do this and I have some ideas; but, I don't want to reinvent the wheel,
if there is a standard solution for this already. I figure, there must be people out there who are actually selling
their PyQt desktop apps and know what they're doing.

Any guidance will be greatly appreciated.
