Google is launching beta testing of the Privacy Sandbox on eligible devices.

 The Android Privacy Sandbox is in development after an announcement in February  2022. This is a multi-year initiative to bring more private advertising solutions to end users through the Topics API and FLEDGE. The goal is to prioritize user privacy by default while continuing to support a mobile ecosystem that relies on ads to support free and ad-supported apps. This is an Android-only solution that uses a standalone SDK separate from the rest of your app code, to ultimately replace Ad ID. Now, the first beta is out, but it's a  bit different from how Google usually does beta builds.

As Google explains, users will be prompted to try out the beta via a notification on their smartphone, and there is no way to manually sign up for the beta. That said, even if you have a Google Pixel smartphone running Android 13, there's still no way to guarantee you'll be able to play in the privacy sandbox. Developers should use the latest developer preview.

Once invited, you can control your participation in beta testing by going to the "Privacy Sandbox" section of your smartphone's settings. From this screen you can view and manage the interests the app can use to show you relevant ads, and block topics that don't match your interests. If you turn the beta off, you can also turn it back on later, so you don't have to turn it on or off all the time.

Apps are also required to participate in beta testing, and there is not yet a list of apps that will use Android's privacy sandbox. However, developers must opt ​​out of Advertising ID. Google has promised to proactively notify developers.
