You're offering a Windows installer for an application that appears to add complexity to simple passwords - probably hashing it with a seed - but without source code, there's no way for anyone to validate the effectiveness of that process, that it doesn't make passwords easier to guess, or even that the app isn't sending everyone's passwords directly to you. You're not even offering a signed binary.

Some people will probably use it and it might work perfectly well but I think most, especially here, are going to be suspicious.
