Important

The Privacy Sandbox Relevance and Measurement origin trial ended September 20, 2023 and the APIs are now available for 99% of Chrome users, and origin trial enrollment is now closed. To keep abreast of the percentage of users each API is enabled for, refer to the Chrome status graphs.

Read the Private Aggregation API overview and Shared Storage overview. See the use cases and review fundamental concepts for the Private Aggregation API.

  1. Try the demo. The code is available on GitHub.
  2. Generate summary reports with the Aggregation Service.
    • Set up local testing. The Aggregation Service for the Private Aggregation API is not yet available to test in a production environment.
