In short, Privacy Sandbox is Google’s attempt to develop new technologies that will improve online privacy while also allowing advertisers to target ads . While the idea of Privacy Sandbox has been met with some skepticism, it’s important to understand its significance. Since its conception, Google has been refining design proposals with app developers and marketers to improve the system for widespread use.
“We plan to roll out Privacy Sandbox Beta early next year so developers can start testing these new solutions on Android 13 mobile devices.”
“We will start with a small percentage of devices and then steadily increase that number.”
Please note that Developer Previews will continue to be released on a regular basis. These are the builds where we will deliver new features first so we can get your feedback before they are released to devices .

Privacy Sandbox for Android uses API systems like “Attribution Reporting”, “Topics” and “FLEDGE” to replace cross-app identifiers and hidden tracking.
The Topics API serves as a classification model that identifies user interests from app usage so that advertisers can be better informed.
FLEDGE is a subsystem of the Privacy Sandbox that deals with ad selection and custom audiences.

Ad targeting serves advertisers by giving them information about which ads were successful on which device, so the advertiser can show the appropriate ad. Meanwhile, audience targeting allows publishers to select readers based on interests.
