Cambridge researchers urge public health bodies like the NHS to provide trustworthy, research-driven alternatives to platforms driven by profit.

Women deserve better than to have their menstrual tracking data treated as consumer data - Prof Gina Neff

Smartphone apps that track menstrual cycles are a “gold mine” for consumer profiling, collecting information on everything from exercise, diet and medication to sexual preferences, hormone levels and contraception use.

This is according to a new report from the University of Cambridge’s Minderoo Centre for Technology and Democracy, which argues that the financial worth of this data is “vastly underestimated” by users who supply profit-driven companies with highly intimate details in a market lacking in regulation.

The report’s authors caution that cycle tracking app (CTA) data in the wrong hands could result in risks to job prospects, workplace monitoring, health insurance discrimination and cyberstalking – and limit access to abortion.

They call for better governance of the booming ‘femtech’ industry to protect users when their data is sold at scale, arguing that apps must provide clear consent options rather than all-or-nothing data collection, and urge public health bodies to launch alternatives to commercial CTAs.

    For christ sake, is there no open source option for such a simple task?

    Edit:
    2 people here could point to drip within 15 minutes of my post, and a third to the fact there are options on F-droid. So why the fuck don’t women just use that?
    Well i guess the ones with harmful advertising have better graphics or somemeting. Or the fact they allow advertising makes them more visible on google play. And you probably can’t even get drip on iPhones.

      I get what you’re trying to say, but this is basically just roundabout victim blaming. Women shouldn’t have to worry about whether or not someone is going to weaponize data on their menstrual cycle against them. Yes it is good to lock your door at night, but ultimately you don’t blame somebody for getting robbed just because they didn’t lock it. You blame the thief.

      Not everybody is as aware of privacy issues as the rest of us. We have to help them, not berate them.

      So why the fuck don’t women just use that?

      They probably don’t know about it. If I search “period tracker” on Google Play, Drip is in about 40th place in the results. That’s several screens down, past a bunch of search suggestions, and the parts where it’s open source, on-device, and optionally encrypted aren’t clear until I tap on it and read the description.

      And you probably can’t even get drip on iPhones.

      There’s some irony in a comment dealing with people making decisions that are against their interests because they’re insufficiently informed speculating incorrectly about something like this when it’s easy to check. Drip is, in fact available for iPhone.

          I’m not sure what the best answer to that is. I don’t think it’s forcing Google to improve its search results.

          I want it to be the average person gaining a baseline level of computer and media literacy such that they seek out and find apps that cannot send sensitive data to third parties without the user’s clear intent, but I don’t think we’ll ever get there.

            Personal responsibility only gets you so far when the big money actively fights against it. I think the answer lies in both holding companies like Google to higher standards as well as improving access to the knowledge we need to navigate what the world has become. It doesn’t help anybody when the FBI has recommended people use an ad blocker for over a decade but nobody has ever heard them say it.

      Because its effort. We have to get the average person to care about their security and privacy before they will bother using these alternatives. It’s much easier for them to download a popular one off an app store and have the data stick with them, than it is to download f-droid, find the right app, make sure its still supported and setup their own data backup.

        To be honest, the backing up is not trivial for most.

        Even for me, while the technical aspect is no problem, the mental burden of thinking to do the backup and then the few minutes it takes to do the backup. Not a problem for a local only FOSS app but its quite a task to keep track of 10+ apps with different backup/export options, backup-passwords and so on. I use a ToDo-App with recurring tasks but still

          Everybody’s a bad ass talking about Darwin awards when that’s something they understand, but suddenly you will expect sympathy when it’s something you don’t. Maybe try havinga little more empathy for the people of the world who are not as aware of how bad privacy has gotten. Believe it or not, we are of a minority perspective. A very small one at that.

          I’m more inclined to believe it’s partially a failure on our part to educate people, but mostly the issue is that it’s not a fair fight. You are expecting the average person to successfully overcome the resources and influence of sometimes decades old, billion dollar, multinational companies and governments. But I guess it’s a lot easier to just call everybody who doesn’t take this as seriously as we do a dumbass. Certainly allowed you to wipe your hands of it and act smug that’s for sure.

              Not knowing how to install F Droid/to look for open source projects for sensitive data is not the same as voting for Trump or supporting Russia over Ukraine. The latter are taking bad information/prejudices and acting on them. The other people simply are not aware of the issue, or how serious of an issue personal privacy has become more broadly. Comparing them to MAGA and calling them stupid is not going to help them.

              I bet if I looked at your smart phone or computer I would see plenty of services you use that compromise your privacy. Should I call you an ignorant hypocrite and berate you as well?

      yes, it is the state of the world, but the attitude of your comment is victim blaming.

      let’s not forget that while we on Lemmy may be aware of the danger of mass surveillance tech, we’re not the majority.

      snowden told us years ago how fucked everything is, and surveillance has only grown since then. let’s not forget that it is not normal that corpo data-mining is the norm (along with included de-facto warrantless surveillance). Even though we all should be better, nobody should have to be as careful as we are.

      hell, let’s be real. As long as we use a smartphone, we’re not being careful enough either.

        Well on iOS there’s the Apple health app. To my knowledge it stores health data locally. I’ll double check now.

        Edit: it does store health data in iCloud by default, but according to Apple its end to end encrypted

        By default, iCloud automatically keeps your Health app data, including health records, up to date across your devices. To disable this feature, open iCloud settings and turn off Health. iCloud protects your health records data by encrypting it both in storage and during transmission. If you’re using iOS 12 or later and have turned on two-factor authentication for your Apple Account, health records are encrypted using end-to-end encryption through iCloud. This means only you can access this information, and only on devices where you’re signed in to iCloud. No one else, not even Apple, can access end-to-end encrypted information.

            I mean, sure - but if you really don’t trust Apple to keep their word, then it wouldn’t matter if their Health app was FOSS or not. iOS itself is still (and probably forever will be) a closed source operating system. That gives them the power to do anything, including hijack the data from FOSS apps.

      Do people need an app for taking notes? Or a calendar?

      Sure, I used to do it on paper for many years. But it’s much more convenient to track it on my phone, which I have almost always with me. That way I can check whether I’m likely to be bleeding heavily before making plans with my friends to go swimming that day or on a long hike without access to a toilet.

      Also many women don’t just track the blood flow but also other data like temperature, cervix and cervical mucus. This helps calculate the most fertile days. It’s much easier to let an app do that.

        Exacty, Drip features tracking for temperature, cervical mucus, the cervix, sex (solo or partner), desire, pain, and mood, along with spotting and your bleeding levels. It’s not just about “when will I have my period?” Additionally I love Drip because of the heads-up notif I get from them 3 days before my predicted period date. Also ut’s nice to have a computer calculate when my period will be and shows me if any were a little off or earlier than expected.

        Plus since it’s encrypted and local, law enforcement would have to crack that to find my period data. I could totally imagine law enforcement coming up with a bullshit warrant and breaking into someone’s home, and finding a calendar or notebook marked with their period data and being tried for it.

      The same could be said of to-do lists, right? But I still like having an app with a checklist, because my phone is always with me and a piece of paper is not.

      When I did have periods (thank god for testosterone), I had a really difficult time keeping track of them and they were often very irregular. The app I used helped me pick up patterns and would warn me when I needed to be prepped. My dysphoria cope was pretending that they didn’t happen ever, so it was helpful to have that occasional “hey, pack some pads today” as a notification without constantly checking a calendar.

    If you have an iPhone just use the Apple Health app. It works great and the data is encrypted and never shared with anyone.

      it can be tracked safely with an app that only stores local data.

      I’m not sure what you’re scared of.

      Drip, the app mentioned several times in this thread, let’s you encrypt the locally stored database with a password you have to enter every time you open the app. How is that not safer than a random piece of paper?

      It’s so exhausting that this thread is full of men telling women what they should and shouldn’t do while having very little knowledge about the topic.

          I’m sorry if I misgendered you. I was already exhausted from the other comments that clearly state that they are men and probably was biased in that regard. But my point still stands that there is no reason to completely forego tracking apps.

            Yeah, and of course I haven’t looked into all of the tech and security of ways to set up these apps. I’m just exhausted myself from it seeming like nothing is ever 100% secure or free from risk, and I’m so cynical about the country I live in and what it will become in the future that I would just rather not trust anything at this point. I’m sure that doesn’t 100% hold water/is completely rational, but it’s where my head is.

              I get that. It shouldn’t be necessary to do research just to be sure it’s safe. I apologise for my aggressive tone. It must be really scary and exhausting to live somewhere like that. My country is still holding up but seems to be sliding slowly in that direction too.

              So do whatever makes you stay safe and feel safe.

      Convenience wins out 99% of the time. Why carry a pen/paper when one can use the same device they already carry around? Hell, I don’t even use pen/paper anymore because my phone handles all that for me.

      That said, I did set up some infrastructure at home that I use to store as much of my private data as possible.

    My wife used to use the tracker in fitbit (I think), but once US states started passing laws to track periods, she’s stopped using it. It’s the wild west in my house now.
