Read my first comment again.

What baseband firmware do you use? And who maintains that firmware?

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.

How does this fix our menstrual apps?

Apple already fixed it years ago when they released iOS 12.

Backing up health records data

You can use iCloud to store your Health data, including health records, using end-to-end encryption (requires iOS 12 or later and two-factor authentication). Health and health records data is also included in local iTunes backups, if you’ve configured your iTunes backups to be encrypted.

Can you name a phone that has open source basebands that has a FLOSS license attached to it? Surely if you're arguing against apple, you are not using a phone that has proprietary blobs in the firmware.

Wrong, as shown above, Apple Health fails to include a libre software license text file. We do not control it, anti-libre software.

'Open source' misses the point of libre software.

Can you name a phone that has libre hardware as an alternative?

How does trapping ourselves in yet another anti-libre app, like Apple Health, help escape anti-libre software or hardware devices?

If libre apps run on proprietary hardware, is it really under your control?

Does Drip, a libre app, move towards or away from solving this?

It doesn't move at all. If your hardware is compromised, then it doesn't matter what apps or software you run, right? Its not under your control.

So which phone has libre baseband firmware?

You want us doing nothing at all unless we get perfect freedom and privacy?

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 legitimately have an idea for an app that solves this problem. Its key feature, besides being open source, would be that people without uteruses could use it too, making any data conceivably collected useless.

I don’t have the skills to make it myself (yet), but if any developer wants to talk I’ll give the idea away. I just want it to be made.

App would be open source, all data local. Perhaps the option to sync to encrypted iCloud or Android equivalent, but certainly not a cloud-based option you need a new login for. All the features currently in these kinds of apps and that make them useful for menstruating people. Now replace “period” with “hair cut”. Non-menstruating people can now use it, earnestly, for tracking when their last hair cut was, making it useful and the data (if it were to be collected somehow) just noise.

I even have a name in mind: “hair**.**cuts” (heavy emphasis on the period in the name.) Idea is that anyone with it on their device has plausible deniability that they are using it for period tracking, but the “period” in the name is an implicit wink so we all know what it’s really being used for.

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.

File this under "no shit."

The humans in my family who experience menstrual cycles have been pretty happy with Clue who have an explicit promise to never give up your data. YMMV and of course you should evaluate what a promise from this organization means to you.

I don't disagree with that, but the point here was freedom from advertisers and general data privacy, not data portability.

But there is an "export all data" feature in health, though.

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