Following the announcement in February and the first release at the end of April, Google is now rolling out Privacy Sandbox Developer Preview 3, which includes APIs and developer resources for conversion measurement and remarketing use cases.
The new release includes two key additions: Event-Level and Aggregate Attribution Reporting APIs. These APIs let developers measure when an ad click or view event leads to a conversion, such as the download of a new game.
“They support key use cases for attribution across apps and the web, and improve user privacy by removing reliance on cross-party user identifiers,” Google says.
The new release also includes Custom Audience and Ad Selection APIs, which are part of FLEDGE for Android. These APIs provide the building blocks to serve customized ads to users based on previous app engagement, without third-party data sharing.
With Custom Audience and Ad Selection APIs, developers can handle impression reporting, configure and initiate on-device ad auctions, fetch JS auction code from remote endpoints, and manage Custom Audience membership and observe how its parameter values may affect auction outcomes.
In the announcement of the Privacy Sandbox on Android, Google said: “Our goal with the Privacy Sandbox on Android is to develop effective and privacy enhancing advertising solutions, where users know their information is protected, and developers and businesses have the tools to succeed on mobile.”
A beta version of Privacy Sandbox on Android for consumer mobile devices is scheduled for the end of 2022.
