Hello everyone,

I've searched around but I've not found anything. I want my user to buy or register the software in my app itself. So I don't want to go to a URL or something like that. I'm searching for a safe and free licensing method, that can check if the user has paid his serial.
Any ideas?

Thanks in advance!

Madmatt.
