First, I'd ask myself how much I care about this. Do I care enough to pay legal fees to defend myself if Snapchat decides to come after me? If yes, consult an attorney and find out what you're looking at. Ignore any legal advice you get here. Unless it's from an actual attorney on your payroll (and attorneys you aren't paying won't give you much beyond an initial consultation)

If no, you've got an easy choice: take it down.
