Arpan Banerjee just sent me that starting June 2025, Google will roll out on-device conversion measurement for iOS App campaigns via the new Firebase SDK (v11.14.0).
This improves campaign optimization and reporting while protecting user privacy (no user-identifiable info leaves the device).
Key points:
– Uses IP and other signals for better attribution.
– Works with third-party App Attribution Partners.
– Automatically activates with the latest SDK and GA4F account link.
– Opt-out options will be available for developers and advertisers.
