The release of Apple iOS14.5 introduced a requirement to obtain an official opt-in from app users to track them across apps and websites owned by other companies, referred to as ATT (AppTrackingTransparency). The ATT Opt-in rate refers to the percentage of users who select the Allow option when they are presented with the ATT prompt in an app.
When exploring ATT Opt-in rates, it’s important to understand how the rate is defined, as multiple definitions have been observed in the market.
Every app user can be one of these 5 states:
The most common definition of ATT Opt-in rate is A/(A+B+E), as defined above, which determines how effective the ATT prompt is at securing explicit permission.
The other definition seen in the market is A/(A+B+C+D) which reflects the total percentage of an app’s user base that has shared identifiable data with the app developer.
