These commercial period-tracking apps are DANGEROUS. They constantly urge you to divulge personal information (When was your last period? Did you have sex? Did you have an orgasm? Are you trying to conceive?), what they eventually do with this pile of intimate data is basically unknown. Will some overzealous law enforcement agency use this data to identify men with uteruses? Will they use it to persecute people who may have had abortions? Will they use it to find pregnant teens? None of those scenarios seem out of the realm of possibility right now.

So if you’re like me, go download a period tracker app and start using the free tier right now. Turn on notifications, and each time you get one, go poke some dates and random buttons. It doesn’t matter what you press. Make their data a little noisier.
