> It seems like we can’t just necessarily leave it up to companies – or their ragtag teams of crackpot lawyers rewriting privacy policies every few months – to keep our private data private.

It's not a medical requirement from a doctor, so just keep a diary if you want to. Not everything needs to be an app. All the money spent on regulations and regulators to cover increasingly niche opt-in services that are entirely unnecessary is a waste.

johnny22•56m ago
privacy legislation would just solve the problem by itself though.
ceejayoz•54m ago
They've been thumbing their noses at EU privacy legislation and fines for quite some time already.
arijun•25m ago
What does thumbing their noses mean? They have been paying while continuing their behavior, or not paying at all?

The first seems like it could be resolved with an escalating fine schedule, and the second could be mitigated by requiring Apple/Google to remove it from the app store (one of the rare cases walled gardens are on consumers' side).

ceejayoz•22m ago
> What does thumbing their noses mean? They have been paying while continuing their behavior, or not paying at all?

Malicious compliance. For example: https://en.wikipedia.org/wiki/Epic_Games_v._Apple

"While Apple implemented App Store policies to allow developers to link to alternative payment options, the policies still required the developer to provide a 27% revenue share back to Apple, and heavily restricted how they could be shown in apps. Epic filed complaints that these changes violated the ruling, and in April 2025 Rogers found for Epic that Apple had willfully violated her injunction, placing further restrictions on Apple including banning them from collecting revenue shares from non-Apple payment methods or imposing any restrictions on links to such alternative payment options. Though Apple is appealing this latest ruling, they approved the return of Fortnite with its third-party payment system to the App Store in May 2025."

Or https://developer.apple.com/support/dma-and-apps-in-the-eu/

"UPDATE: Previously, Apple announced plans to remove the Home Screen web apps capability in the EU as part of our efforts to comply with the DMA."

(This one resulted in enough fuss they backed down.)

Zak•48m ago
Privacy legislation by itself does not solve the problem; what Flo did was already illegal. Effective enforcement is also necessary.
kortex•10m ago
They need to make an example out of these companies. If your whole business model is built around handling sensitive data, and you are caught shipping off that data to brokers, you should be liquidated or at least fined to within an inch of bankruptcy, as basically all of your profits are a sham.
krystalgamer•30m ago
"would just solve", lol.
sdoering•55m ago
Why is it a waste? If you want to provide an app, one should follow the law and the regulations. It isn't the wild west (and even that had regulations).

Also: Why blame the victims, not the perp?

kakacik•41m ago
Nobody is blaming victims, please stop these wild fabulations. OP meant that you can't trust app owners especially long term, as you write its worse than wild west, literally nobody.gives.a.fuck. till they are dragged to the court, then they fight, dissolve company, still sell the data, start a new one and rinse and repeat. People are simply way more greedy than moral on average if there is any lesson in current times.

Look at say zuckenberg - a typical sociopath lying again and again through his nose with big grin just to get what he wants (ie scandals how FB employees go to DB to spy on their exes or enemies is popping up for 10 years at least and there is no stop, every time there is another assurance how it can't be done now blablabla... and thats just specific meta employees).

Nobody likes that, but just sitting and waiting for almighty regulators while blindly trusting apps in good faith to do their jobs is... not working much, is it. Be smart, adapt to real environment out there, not some wishful thinking. In parallel push for change as much as you can, vote with wallet and your time. Once sought-for paradise comes then feel free to use anything anyhow. At least that seems like smarter approach to me.

ndriscoll•27m ago
> still sell the data

So add liability for the buyers of the data or any services derived from the data (e.g. targeted ads). Make it so large advertisers demand audits showing privacy laws are being followed. Also have personal criminal liability for people building and maintaining systems that collect, store, or process data for illegal purposes. Executives, PMs, engineers, the whole lot. Put them in prison if they continue.

I'll make a period tracker for you for 5 bucks a month. You won't buy it, because it costs 5 bucks a month. So I'll have to find alternative monetisation strategies.
moffers•31m ago
I don’t have the right configuration of equipment to use an app like this, but does anyone know why this needs to be a service-driven app? What piece of functionality requires a server to track your health?
jumpconc•10m ago
The spying part requires a server.

If you use GrapheneOS, you can enable or disable internet access for each app.

childofhedgehog•31m ago
Why would anyone think that a non-HIPPA compliant app would keep medical information private to the level of security needed for medical data? Flo has definitely breached user trust, but that trust seems misplaced from the get-go.
john_strinlai•24m ago
>Why would anyone think that a non-HIPPA compliant app would keep medical information private to the level of security needed for medical data?

because lots of people dont know what HIPPA is, and (naively to us more familiar with tech) assume that a medical-related app on a curated app store would be safe for medical-related stuff.

ceejayoz•20m ago
> lots of people dont know what HIPPA is

Ironically, it's HIPAA.

You're right, though; it's much more limited than people think. During COVID people claimed everything violated HIPAA (masks, vaccine requirements, testing), but it only applies in a very narrow subset of patient/provider relationships.

gizmo686•18m ago
People are used to living in highly regulated markets. When they go to a grocery store to buy lettuce, people don't stop to ask "what regulatory regime is this lettuce being sold under?". They just trust that food being sold in a food store will meet our societal standards for food. I can go to Amazon and order a raw steak for delivery, and still trust it will meet standards.

The situation with wellness apps is that they are a product that are designed specifically to exist outside of the regulatory regime that people associate with them.

elAhmo•16m ago
People just wanna track stuff, they don't really look into is something HIPPA compliant or read the ToS. App store push, recommendation, word of mouth are what makes the app like this spread, not really details HIPPA compliance.
frankdenbow•30m ago
its crazy to me that Flo is used so widely, as its started by Russian men and their treatment of data has bee public for a while, it just hasnt spread fast enough. I know theres at least one other option called Calessa (http://Calessa.app)
aboringusername•25m ago
I don't actually see this as a problem, and instead it's a PSA everyone needs to internalize:

If you put data onto a networked device it may be sent to some place else.

If you don't want your data being shared:

Use a device that does not have any networking capability (both hardware and software wise)

Use a pen and paper, you can shred and destroy as you see fit.

If you're using an application on a mobile device with mobile data/wifi, the chances are, your data is being uploaded.

boesboes•20m ago
that is a really fucked up view
defrost•14m ago
Less a f-u-view, more a f-u-world, the above is pragmatic advice about the actual IRL challenges of keeping data secure.

Further, a view that ignores many real world digital data risks faced by those considered to be useful targets; eg: compromised supply chains delivering "pre hacked" hardware with discreet wifi chips or hidden out of band comms, etc.

elsjaako•17m ago
There are four open source period tracking apps on F-droid. I didn't do a full investigation of the source code, but unless your data is being uploaded outside the app (e.g. for backups), I feel safe assuming it will stay local only.
reorder9695•6m ago
It sounds like the real solution to this is to be able to control permissions at an OS level for network per app, as you would be able to do if you had root access. I have no idea why regular Android distros don't allow you to do this, it seems like a really sensible thing to expose in app settings given the permissions model of Android.
