Is it normal for kids to just not regester swear words?

I swear a moderate amount, my wife dosent swear often but does when mini disasters occur. Our daughter (almost 7) just dosent regester them at all. She dosent know any swear words, dosent pick them up at home, her school is progressive and teachers clamp down on this sort of thing completely.Is this normal behaviour?
