Check out your iPhone’s Settings > Privacy and scroll to the very bottom. You’ll see “Analytics & Improvements” and “Apple Advertising”, which both contain toggles and details about the data that has been gathered so far. There was also an iOS update in the past where the onboarding flow asked me to grant these permissions, though I vaguely remember seeing it on every major iOS version update.

Now, that’s not to say that the iPhone setting guarantees that Apple is not up to something sketchy. We can’t tell what’s going on under the hood or in their servers, but if we really wanted to be extremists about privacy, then we have to resort to apps that we’ve built and self-hosted ourselves.
