Terms of Service
I'm apparently required to write Terms of Service.
Shift Scheduler is a free application. You're free to use it however you'd like, but don't do any very bad things with it, like scheduling a murder or something I guess, because then I'd have to disallow you from continuing to use the application (and you'll go to prison).
It's designed with medical residency shift scheduling in mind, but as I mention in the application tutorial and help sections, it is NOT to be used for patient scheduling as it is not HIPAA compliant. If I find out you're using it for patient scheduling I'll disallow you from continuing to use it, as this is a serious patient privacy violation.
