Love the period app Stardust's daily horoscopes and moon-witch vibes, but worried about data security?

Not all of that data is innocuous; in some cases, the data being shared can include things like your birth control method, like whether you use medication or an IUD, your reproductive goals, like whether or not you’re trying to conceive.
