While the explanation is great, I feel like it shouldn't even be necessary. Like, if people are using an app, can we not just assume that they have a reason for it? A reason that, to them at least, is a good one? Regardless of what the app is about, or which demographic is using it, it seems infantilising not to make that assumption.

Periods are never properly explained in school, a lot of people simply get taught by their mother, or survive with what little knowledge the biology textbook holds about them.

I cannot blame someone for not knowing how awfully complicated they are, when school at most teaches about the ideal period, not even mentioning how much can affect them, or how awful they can be for some people.
