It’s honestly kind of disturbing. Period tracking apps used to feel like a helpful tool, but now they feel more like surveillance. Most people have no idea their most personal data might end up in an ad network.

What we really need is stronger default privacy, not just longer consent forms. I’d love to see more apps that are local-first and don’t upload anything by default.

Can anyone tell me why this would be as much of a problem for safety as they are saying? The only thing I can see happening is easier selling of pads and tampons during a certain phase of the moon. Apparently this is what the article suggests too, that certain things are easier to sell at a certain point in the cycle. It’d be embarrassing if someone knew, not dangerous. And even that much feels weird to me for a very…

Woman gets pregnant, flagged as such in business intelligence database, she doesn't start buying baby stuff and instead travels out of state, suddenly treated as criminal suspect. https://www.eff.org/deeplinks/2025/05/she-got-abortion-so-te... I cannot fathom why you think that highly personal data like this should be sold or shared with law enforcement.

I’m not saying it should be shared. I’m just struggling to come up with truly terrifying things you can do with the information.

That whole article is going mental over the fact that a cop can run a nationwide search on license plates of all things? What’d be the point of running it on a select few states?

“I’ve established that the suspect is not in Texas.”

CNN: “A West Virginia prosecutor is warning women that a miscarriage could lead to criminal charges”. A gap in periods followed by their resumption could theoretically be enough to lead to prosecution.

The problem here is definitely not that someone has information about who is on their period.

You mention Pokemon Go... this would basically be the end of that game, no? That's probably worth the tradeoff, but worth mentioning.

People are already spoofing location, and it hasn't been the end of the game so far. Or did I miss something?

It depends on how many people are doing it though, right? If you make it trivially easy by building the functionality into the operating system—and potentially even prompting people to lie when the app asks for their location—I feel like things would be very different.

Blocking network access by a specific app at the OS level would be the way to achieve this. I don't believe iOS currently has this ability (all network, not just cellular). Android has solutions like NetGuard.

But you can make updates manual instead of automatic, that’s something.

The issue with this in practice is that it collapses to one of (a) never take updates ever again or (b) risk that any update changes privacy behavior.

Given that it's impossible for a user to vet each update's content effectively.

I agree about a) but b) does not make sense to me, otherwise you cannot instal the app in the first place. I think that a quick internet search about the apps privacy is sufficient for b), definitely better than automatic updates. And it does not have to happen for every release.

FYI - many couples track cycles because they are trying to get pregnant.

Yes but as I said in my post - it's not effective. Hormone measuring strips are and they costs very little - $2 / month - and are very effective. We wouldn't have three kids now if we relied on counting days.

You use them in conjunction with each other. For instance, if one of you travels for work, you can try to plan around when you think the next cycle will be.

A strip confirming you’re ovulating is pretty useless by itself if your partner is on the other side of the country.

there is an alternative contact app that doesn't share your data. you can then fill the default contact app with fake data or leave it empty. i am not sure if the last point is a good idea though. i get what you want to achieve. anonymity in numbers and plausible deniability, but you are more likely to get mixed up with problematic stuff others are doing rather than protecting yourself. having a common name already s…

> there is an alternative contact app that doesn't share your data. you can then fill the default contact app with fake data or leave it empty. You may want to share your contacts with app X but not with app Y, though.

yes, fair point. i solve that by using shelter where the app and a contact app run with an independent configuration. the downside is that i have to duplicate contacts in the shelter vs outside. however that is what i want because not all contacts are duplicated.

As I had failed finding an app that was not ad-ridden or oldish, my girlfriend and I are using this (I am copying her values, to know when her period will be). Also contributing some code :)

Can I ask why you use it? We used test strips - they're really cheap and way more accurate as women's bodies aren't clocks. That was effective for getting pregnant. Using anything except some kind of active measures to avoid pregnancy doesn't pass my engineer brain and certainly doesn't pass my wife's Pharmacologist brain (i.e. she actually knows what she's talking about whereas I'm using applied probability theory w…

For the opposite FYI; some aren't trying to either target or not target pregnancy, they want to have a forecast for the next 3 days so they can pack their purse.
