That would be for
@Bartolomeu o Portugues to decide, since she's part of his storylines.

Anyway, the difference between privateer and pirate is that the former does his - or in this case, her - raiding on behalf of a nation under a LoM, and Roxanne goes on to say that she has a French LoM. That's also the distinction you make when you choose the Corsair character type - if you pick a nation then you get the relevant LoM and become a privateer, if you pick Pirate then you become a pirate. Roxanne apparently picked France.

But she's perhaps more independent-minded than some privateers and not averse to joining forces with an outright pirate, e.g. Bartolomeu. All of which means "I'm not a pirate, I'm something that could also be a pirate" is about right.
