An Ecosystem Update & Insights on Investing in Privacy

Since Apple’s April iOS update went into effect, the share of users who have upgraded to iOS 14.5 or higher has hit 70% worldwide, according to AppsFlyer’s iOS 14+ benchmark data.

With iOS 14.5 upgrades well underway, Apple’s privacy updates and ATT (App Tracking Transparency) enforcement will continue to impact advertisers’ ability to garner insights and attribute campaigns. Going forward, it will be important for advertisers to proactively communicate about privacy and data usage with their consumers.

eMarketer was pleased to moderate a Tech-Talk Webinar featuring AppsFlyer’s Chad Greenleaf, senior vice president, client services, and Barak Witkowski, vice president, product, along with Stash’s Tyler Pennell, vice president, growth. Together they shared valuable lessons learned throughout the iOS 14.5 readiness process, where the industry stands now, and best practices for a privacy-centric future.
