Ask before any tracking

How to do it

Apple counts as tracking any link of your app's data with other companies' data for targeted ads or ad measurement. Sharing with data brokers counts too. Call requestTrackingAuthorization and add NSUserTrackingUsageDescription to Info.plist, or the app crashes. Never lock features behind a yes, and never reward one. Start ad and attribution SDKs only after a yes. Android has no system prompt, so use your own consent screen, as track only after consent says. An app that does no tracking asks nothing.

Examples

Plain text example

import AppTrackingTransparency

let status = await ATTrackingManager.requestTrackingAuthorization()
if status == .authorized {
    AdAttribution.start()
}

TypeScript example

const status = await consent.requestTracking();
if (status === 'authorized') {
  adAttribution.start();
}

How to check

On a fresh install, answer no to the tracking prompt and capture the app's traffic. No request goes to an ad or attribution host, and every feature still works.
