If anyone is in need of a more secure option in these dystopian times: drip keeps all your data on your phone. You can export the data, so you can keep the tracked data when changing phones. I only use it for tracking my cycle and sometimes symptoms though, so I can't say much about using it for birth control.
I know it's not feasible, but if a lot of males would just use the apps that are know to report to US authorities and input data, that most likely will raise a alarms, they would have to deal with heaps of false-positives and it would obscure the real data.
If you absolutely have to have it in your phone, use the calendar and pick some event that's plausible monthly with a unique name so you can search on it. "Checked for Mxyzlptik updates", "Look at travel to Canada prices" or whatever.
If you need more functionality than that you'll need an offline solution. We live in a fascist dictatorship now. They hate women. And they will 100% use that information against you if they can.
I'm glad this article is about Clue. I hope I can continue to trust them.
I've been using Clue for years and it's nicely trans-friendly and not-pink. When I was first looking for a period app, many options were focused on fertility--either seeking or avoiding pregnancy--which rubbed me the wrong way.
As a man who have been with the same woman the last 20 years I have an extremely limited experience in the field of periods to put it mildly, but what benefits does using these apps give you.
Could you get the same effect from an airgapped notebook?
