Thank you for not taking any offense to my frustrated tone, as it was indeed just that, frustration. Having questions and posting them here is completely understandable, and for what it’s worth, I’d rather people ask than just never get an answer.

Though you are allowed to have your own opinion and come to your own conclusions, I think the fact you stated that you think using the apps was a bad idea even before now, and that doctors have been helping people long before apps, demonstrates that either I was not clear enough, or you were unable to appreciate the lived experience of people affected by their periods.

Doctors regularly misunderstand, misdiagnose, and outright ignore period related medical issues. I’m not sure where you live, but even in a country with the best healthcare in the world, it’s literally impossible for doctors to provide the personalized information that apps can. I’m not saying that apps therefore must be used and are better than doctors, but I, a woman with periods, am telling you that my app has been more helpful than my doctor as far as managing my cycle goes. You don’t have to believe me, or you can say that you don’t think anything is worth the trade off in data for you as an individual, but people using these apps would obviously disagree. And not just because they don’t know they’re being tracked. We’re all being tracked to a certain extent and we decide what we’re willing to put up with in exchange. If you don’t think you’d share your data for that convenience, fine, but people share data for other conveniences all the time. It’s just extremely unfortunate that this data has now become so contentious.
