The article compares iOS's SKAN (soon AdAttributionKit) and Android's Privacy Sandbox Attribution Reporting API, highlighting their shared privacy-first principles of obscuring identifiers and using data aggregation.
SKAN is a closed, iOS-only system with strict 2/7/35-day reporting windows, significant delays (24-144 hours), and limited data granularity (6 bits for conversions).
Privacy Sandbox is more open and collaborative, offering flexible 30-day reporting, faster aggregatable reports, and much higher data capacity (128 bits), though it requires careful budget planning and adds noise for privacy.
Key differences include SKAN's simplicity versus Sandbox's complexity and innovation potential, with both posing challenges for cross-platform analysis, emphasizing the need for tools like AppsFlyer's Single Source of Truth.
