Not all women menstruate, and not all people who menstruate are female.
It's a sea of well-meaning ridiculousness, that doesn't make me want to use clue when there are so many other period tracking apps out there.
It's also the co-opting again - 'not all women menstruate' - no, they don't they might be pregnant or on birth control, or post menopause, or have had a hysterectomy, or have some kind of disorder - plenty of reasons. None of these reasons apply to males. None of these non-menstruating women are emailing clue asking for more inclusive language because they feel left out of an app they don't need.
Don't use non-menstruating women as a way to shoehorn men into the woman category.
