I wish that it was more prevalent for people to just assume and know that any website, regardless of whether or not it has a chat function, has the ability to record what you're saying (read: typing). Everyone out there should act like everything they type into their web browser has the potential to be seen by, at the very least, the website they're typing it on and, at worst, by everyone online.
If you really need the kind of security or peace of mind that this situation is not suitable for, type everything into a text editor and paste it into the website when you're ready to send it. Otherwise, you can't ever have any expectation of privacy on the web.
