The CNN article talks a bit more about privacy issues. This bit caught my eye:
It’s only available on iOS because Aaron says the app would have to collect information that could ultimately put users at risk to provide the same experience on Android.
I would like to see some details about this. Perhaps there’s a way to work around that problem, even if it meant publishing on F-Droid instead of Google Play.
Only for iOS… Oof.
At this point my understanding from other sources is that they can’t distribute via the android App Store in a way that uses location tracking and notifications but is still anonymous where they can with iOS because location services is device side only.
Android Location manager can get the location without Google Services and there are alternative notification services like ntfy.
EDIT: The location manager is part of the official API and ntfy is available on the play store, so apps using them will also be allowed. Besides, it’s android, you can install alternative app stores or install apps directly. Maybe it’s a good time to teach vulnerable communities how to do it safely, because using Big Tech services is not safe for them.
Fused Location Provider data sent to Google is anonymized with a temporary device id anyway. They also can’t tell if you needed location for this, maps, or Pokémon Go. But they do sometimes collect GPS, WiFi, and cell data. Not using it is more private but I don’t think it’s worth worrying about.
