"Restée" is the correct past participle for a female, right?
You could program to accept both male and female answers, perhaps.
Women and girls need to get in the habit of using the feminine.
Yeah, yeah, I know that genderless is coming down the pike, but for now it is incontrovesial that women use feminite forms in French. How elegant it would be if I could write, "Je suis restée."
