App Tracking Transparency (ATT)

App Tracking Transparency (ATT) is Apple’s iOS privacy framework requiring apps to request user consent before tracking across apps or websites. It significantly impacted mobile attribution and personalized targeting. For advertisers, ATT limits data availability but also encourages adoption of privacy-compliant measurement. Publishers must adapt to retain ad revenue in this new privacy-first environment. Partner with Blasto to run compliant campaigns in the ATT era without losing performance.
