Party Hooking My Keyboard

[SlowHabit]

For a while, I used SnoopFree to prevent Party from hooking to my keyboard because I was paranoid that they might know what my passwords are for other things I do online while playing. However, I want to be able to say "hi" or "thanks" while playing so I enable it again.

My question is: Is it possible for Party to know what I type on web browsers but not in their chatbox?

Thanks.
