Private advertising
Multiple technologies to serve advertising use cases have been developed as part of the Privacy Sandbox initiative.
We will continue to retain information on this site, even for features that have not been implemented or that are scheduled to be phased out.

Core private advertising APIs
Some of these APIs are scheduled for phaseout: see individual guides for more information.
Protected Audience
The Protected Audience API serves remarketing and custom audience use cases without third party cross-site tracking.
Attribution Reporting
The Attribution Reporting API enables measurement of ad performance without third party cross-site tracking.
Private Aggregation
The Private Aggregation API has been built for aggregating and reporting on cross-site data in a privacy-preserving manner.
Topics
The Topics API enables interest-based advertising while preserving user privacy.
Additional services, infrastructure, and APIs
Learn about shared services that were designed to work with the private advertising APIs.
Aggregation Service
The Aggregation Service processes aggregatable reports from the Attribution API or Private Aggregation API to create a summary report.
Shared Storage
Shared Storage allows unlimited, cross-site storage write access with privacy-preserving read access.
Bidding and Auction
The Bidding and Auction server allows a Protected Audience computation to take place in a trusted execution environment rather than running locally on device.
SDK Runtime
The SDK Runtime allows SDKs to run in a dedicated sandbox that's separate from the calling app.
