SKAdNetwork (SKAN) is an Apple framework crafted to gauge conversion rates for mobile app install campaigns while safeguarding user privacy. It functions on an aggregated level, preserving user anonymity and abstaining from disclosing detailed per-device data. SKAdNetwork empowers ad networks and advertisers to assess their ad performance without divulging individual user or device information. Its significance has heightened with the advent of iOS 14 and the introduction of the AppTrackingTransparency (ATT) consent mechanism.
