Privacy Sandbox
The Privacy Sandbox is a Google initiative, begun in 2019, to develop web and Android technologies intended to support advertising and measurement with stronger privacy. Its direction changed substantially: in April 2025 Google decided to keep third-party cookies in Chrome under existing user controls rather than introduce a new prompt, and on October 17, 2025 it announced it would retire most of the advertising and measurement APIs — including Topics, Protected Audience, Attribution Reporting, Private Aggregation, and IP Protection — citing low adoption. Google continues to support privacy and identity features such as CHIPS, FedCM, and Private State Tokens, and is pursuing an interoperable Attribution standard through the W3C.
