I'm very curious how this works, so this is from a report [0] from Flurry Analytics, "owned by Verizon Media, is used in over 1 million mobile applications, providing aggregated insights across 2 billion mobile devices per month" How is Flurry Analytics measuring app tracking on iOS devices? Are they just reporting how much they themselves are being disabled?

I believe so, which is why that % is very small. I’ve seen quite a few reports from different providers in the last couple of weeks and suspect the _real_ average of opt-ins is considerably higher. I’m hoping to see some numbers from Apple at WWDC, which I expect would be in the 30-50% opt-in. Why? Because some apps (like Facebook) make it seem like it’s mandatory to opt-in. And I believe that if you opt-in for Facebook you’re more inclined to just hit that same button for every app…

  I disagree that Facebook makes it seem mandatory. Receiving their in-app popup yesterday brought me great joy in denying access.

    Haha. I totally get that. But… I don’t think that popup was designed to get the HN folk to opt in but rather those that use Facebook (and Instagram, which has the same language) to communicate actively. It’s really the pre-prompt I’m referring to here, which, as one of its bullet points for why you should opt in, says it helps keep Facebook free. That’s a big statement to drop in a tiny bullet point, which makes me feel like they thought about it a lot. Meaning, it’s very targeted.

      I flatly refuse to have the Facebook app on any of my devices, and if they start charging to use it I'll happily delete my account.

  Apple has guidelines on the screens displayed before the opt-in. I've seen apps fail audit because of the pre-text.

    Yes, but a quick look at attprompts.com will show you most apps that use pre-prompts do at least one thing that’s not allowed by the rules. I Worte about a few, including McDonald’s which uses misleading language and a popular game that shows a fake prompt altogether. https://appfigures.com/resources/this-week-in-apps/20210430#1-digging-into-app-tracking-transparency https://appfigures.com/resources/this-week-in-apps/20210430#...

Flurry provides an analytics library to app makers that gets compiled into their applications and then reports back. Flurry compiles data from all users and apps and gets a global portrait.

The setting controls whether Flurry can retrieve the advertising id (IDFA) which allows for cross-app identification. Without that, Flurry can still count devices using an app, but cannot identify if they are the same across apps. So they can easily sample what portion of an apps users allow access to the IDFA.
