Simple + open source + no access to network + no updates (idk about Android/iOS cross-app data sharing).

Still data can be uploaded to the cloud and will be available to cloud providers. So there is more vectors to protect user data.

It is painfully evident sometimes that America desperatelyl needs a GDPR-like federal law. The state-by-state laws are by nature peicemeal and it makes for a wild west of outright PII abuse.

Even if you could create such a law, at this point in time, no law can protect americans agains persecution by government-affiliated groups who are immune from court scrutiny thanks to their protections at the very top. You would first have to send corrupt SC justices to prison, impeach Trump and prosecute all his henchmen. Forgive me, but i doubt this is going to happen now that the US is officially a dictatorship. There is no point in laws if you have no independent courts and almost no one is willing to stand up for democratic principles.

Historically, "safety" referred to protection from physical harm. It has now expanded into psychological, emotional, economical realms. This had the (very much intended) effect of redefining "unsafe" from imminent and persistent threat to anything that makes me uncomfortable .

In America, in many states, you can be imprisoned for having an abortion. Sharing your menstrual data and therefore having it available for subpoena is quite literally a physical safety risk. If you don't understand, or disagree that the word "safety" is entirely appropriate here, can you talk about why?

I understand, and I do agree. I simply answered the GPs question.

Paper is easier to destroy quickly, and to also plausibly lose or deny having. This is actually one of the biggest problems I've found with Yubikeys: they're both too fragile yet also hard to reliably, deliberately destroy quickly.

I really don't agree. If I take a photo on my phone, it can be deleted in less than a millisecond. Shredding a paper calendar takes at least 30 seconds. I don't see denial of ownership as a legitimate strategy to data confidentiality.

Assuming the ToS for your photo app didn't change at some point and do something different with the data.

It can be marked as deleted in the file table. Destroying a paper can be done on the toilet or simply eaten.

In the current climate, no one should use a menstrual tracking app of any kind, even those with on-device-only data. Asking normal people to figure out the risk profile of that data, and to evaluate the trustworthiness of a given app, is just too much. Use a paper calendar.

The risk profile of paper seems to be equal to the risk profile of on-device-only? How do they differ? Something you have v. something you have

You can give file access to other apps on your phone, no? Apps can be sold to a new owner with different views on what to do with this data. Data on a device vs data on an Internet connected device vs paper have obvious differences.

The practicality of dragnetting it. Google and Apple could decide or be forced to start syncing that previously only-local data. There is no central entity to mass-collect paper without sending out an army of people to raid homes.

They don't need apps to do this. I sat in a meeting with a data broker in 1998 where one of their managers was chuffed that they could determine menstrual cycles by analyzing purchasing records. And it wasn't hygiene products. Various foods and other spending patterns pop out after a 28-day correlation over groups of women that are artificially "synced" into cohort groups. This invasiveness will continue so long as t…

Joke's on them, my wife likes ice cream every day.

For those wondering why this is a safety issue, in many American states abortion or "fetal harm" is considered murder. You can be imprisoned, theoretically for life. This is of course a rapidly evolving area of law since the fall of Roe v. Wade. Having one's menstrual data available for subpoena is therefore quite a literal safety risk.

Then you haven't tried looking. Women are being arrested and even convicted for having miscarriages, including in the US.
