I can understand that. We are also working on an encryption feature that doesn’t use the default encryption primitives so people can have custody over their own keys and feel better about their data security at rest

Is that better than using the secure enclave type of default? Not everyone is an HN reader that would even know what a personal/private key pair is let alone how to properly/securely handle them.

True, but for many, even “local only” apps store their data on devices managed by US-based companies. Would Apple sell your data to advertisers? - probably not. Would Apple share your data with law enforcement? - of course, and they don’t even need to tell you.

why why why are you using a company device for such personal information? don't do this.

I don’t believe they mean storing it on a company owned device, just that Apple and Google are US companies

Then you haven't tried looking. Women are being arrested and even convicted for having miscarriages, including in the US. https://www.bbc.com/news/world-us-canada-59214544 https://www.nbcnews.com/news/us-news/georgia-arrest-miscarri... https://churchandstate.org.uk/2015/01/conservative-dream-com... https://www.cnn.com/2025/06/06/health/miscarriage-criminal-c... https://www.themarshallproject.org/2025/04/02/law-pregna…

Every single of the six links you provided are about miscarriages and not abortions. Either I don’t understand something medical (not a doctor), or you’re mixing things to derail a conversation (dishonestly or unintentionally). Whether those miscarriages were natural or a result of human malice, is an absolutely separate discussion.

How does all that prove an original point that an abortion can get a woman to prison?

Combine this with the Meta Pixel illegal localhost tracking that bypasses privacy measures [1] [2] and the privacy leaking could be off the scale. I think this goes for all things - medical data such as heart rate, blood sugar, steps, weight, VO2 max, etc, could all be seriously misused. Personally I try to use apps that are not cloud-based, or make my own, but this isn't an option for everybody. [1] https://www.zero…

You don't need a Meta pixel if the app simply... shares the data with Facebook, as Flo was caught doing.

Not sure how that's super relevant here? "my data could be used to accuse me of a crime" is a threat of physical harm anyway, unless you define being arrested as safe. And I don't really think public opinion has shifted on that part. You could argue about emotional comfort or something, maybe.

Being arrested by a “public safety officer” is not safe at all.

You could probably find 10 separate videos of "public safety officers" assaulting innocent people by shooting them with rubber bullets for no discernible reason or by trampling them with horses (also for no discernible reason), and that's only from the last 2 days.

Duress modes are a frequently overlooked feature in general - e.g. I don't want to just block access to my location, I want to lie about my location entirely.

I also would like “give an incorrect location” as an option. Something like that would probably never be supported by Google or Apple officially, because unlike some other privacy features, it’s actively and overtly hostile to advertisers.

regardless of what apple/google allow officially, the cell carrier also has tracking locations. if you're going out to do something that you would want to hide your location, it's best to just leave the device at home. get a burner phone paid for in cash by someone not you doing the transaction.

If anyone is interested in a privacy focused tracking app that stores all your data locally, I make an app called Reflect [0] whose sole purpose is this, plus on-device analysis. We’re working on a menstrual tracking feature right now and it’s pretty far along. We’ve just released an anomaly detection feature as well. [0] https://apps.apple.com/us/app/reflect-track-anything/id64638...

For people living in the US of Freedom, wouldn't it be good think to 'keep putting in' cycles, despite pregnancy? Should anything untoward happen later, a quick flash o' the app and "Nope, Officer, no siree. Like clockwork, me...".

As with most advanced features in Reflect, we’ll expose a low friction version to those who don’t want the control, but also the option for more control in the form of key management if they wish
