An Android-specific identifier used for ad tracking. Install referrer is a unique string sent to the Play Store when a user clicks on an ad that is similar to device IDs and device probabilistic matching. When the app is installed, the referrer is sent to Kochava and may be used for attribution or to mitigate fraud.
Per Apple’s user privacy & data use policy, fingerprinting and probabilistic forms of attribution are restricted when an iOS 14+ user has not opted-in to tracking under the AppTrackingTransparency (ATT) framework.
