When Apple announced period tracking in its Health app, there was another round of articles of how Apple eats its own from the app store.
I mostly agree that it's problematic that Apple runs the App Store AND competes with other apps on it. But we have to take this sort of thing into consideration too.
But we have found again and again, that these third party apps have absolutely no data protections and will happily sell your data to other entities.
So if you want to track your period (and other such sensitive data) and not have your sex life sold to everyone, use the first party app. Even Apple can't see your data.
That stuff would cut into the planet-size hoard of profit Apple makes off the app store, though, so I wouldn't hold my breath.
There are dozens of times when app developers say "oops" during a data sharing leak, either because they want to fake not having known that they were sharing data, or (probably more likely) they were using an SDK that itself was leaking tons of data that they didn't know they were signing up for.
Apple closes loopholes, the press cries about App Store dominance, app developers cry out, new rules are put in, and then they circumvent those rules. Rinse and repeat.
Edit: "impossible" -> "nearly impossible"
If personal data companies don’t start regulating themselves they will get it forced on them by the government. Financial, medical, and defense companies already do it.
Aka the Facebook model.. tldr: "developer, click here to promise to behave". Aka the "click here if you are 18 or older" model. Thanks Zuck, for giving us Cambridge Analytica.
What a bunch of effing liars. "We promise we keep your data secure" is yet another meaningless statement...
I try to shy away from blanket statements but this seems like a pretty good one :P
