Apple’s Cycle Tracking app is also locally and E2E encrypted in iCloud.

When your phone is locked with a passcode, Touch ID, or Face ID, all of your health and fitness data in the Health app, other than your Medical ID, is encrypted. Any health data synced to iCloud is encrypted both in transit and on our servers. And if you have a recent version of watchOS and iOS with the default two-factor authentication and a passcode, your health and activity data will be stored in a way that Apple can’t read it.

This means that when you use the Cycle Tracking feature and have enabled two-factor authentication, your health data synced to iCloud is encrypted end-to-end and Apple does not have the key to decrypt the data and therefore cannot read it.

What a name lol

their given reasons are "to keep backups" and "academic and clinical research with de-identified datasets"

they seem to actually do a fairly good job with anonymizing the research datasets, unlike most "anonymized research data", though for the raw data stored on their servers, they do not seem to use encryption properly and their security model is "the cloud hoster wouldn't spy on the data right?" (hint: their data is stored on american servers, so the american authorities can just subpoena Amazon Web Services directly, bypassing all their "privacy guarantees". (the replacement for the EU-US Privacy Shield seems to be on very uncertain legal grounds, and that was before the election))

When they start prosecuting women for miscarriages and suspected abortions under Trump's national abortion ban.

dystopian hellscape where government has an algorithm to check whether your period has come in a given month, and if you've missed more than a few weeks, you'll be listed as pregnant. And then if you're not pregnant anymore for any reason other than giving birth, then you'll be prosecuted for having an abortion.

To prosecute criminals. Like women not following a shit take like "Your body, my choice". Or terrorists. With wombs? Idk.

This shit is just fucked up.

China had a database that stored fertility information including information like in the article leak a few years back too. Worse cause it leaked/got hacked. Creepy AF

I imagine they collect data to improve their algorithm so it can more accurately predict a woman's cycle. Quite a few women use these apps as an alternative birth control, so knowing the specific days where they need to avoid sex is helpful.

I can recommend Mensinator. It includes logging and calculated ovulation day too. Something I could not see in bluemoon screenshots.

All US-based apps and all the apps that store their data in US-owned cloud providers at very least.

I'm in. Anyone know of any apps that DO report data?
