Hi Freddie,
Thanks for your input I appreciate it. I would definitely agree.
To shed some light on it, I do not use a global keyboard hook.
Here's basically the code that does it. All it does is calls Window's API to register and unregister global hotkeys:

Besides posting source code, what can I do to prove legitimacy?
Welcome and good luck with your software. I don't think it's possible to prove that a program doesn't contain malware or that it can't break rules.
Of course you can avoid certain features that people find particularly scary, like global hooks. Probably this would encourage more people to try the program. But there are several other methods for logging every keystroke, so this doesn't prove anything.
I think the main thing you can do is act responsibly and over time, if nobody complains about your program, more and more people will trust it. It has to be handled as a social issue not a technical one.
