Android Privacy Sandbox Will Enter Beta in Early 2023

As of early 2023, a select group of Android 13 devices will start receiving the Android Privacy Sandbox technology, according to a recent announcement from Google.

Google unveiled a suite of technologies called the Privacy Sandbox for Android in February of this year with the goal of limiting user monitoring while still giving marketers useful performance-measurement alternatives.

Since then, Google has improved the system and prepared its components for possible deployment by debating alternative design concepts with app developers and marketers.

According to a news release, “we expect to push out the initial Privacy Sandbox Beta to Android 13 mobile devices beginning early next year so that developers may take the next steps in evaluating these innovative solutions.”

We’ll begin with a modest number of devices and gradually grow it.

The latest features will be delivered in Developer Previews first for early input before being launched on production devices; therefore, take note that these releases will continue.

App developers are encouraged to sign up so they can access the system’s APIs and start working on their integrations right away, all the while assisting Google with the upcoming testing phase.

The testing for the Privacy Sandbox SDK Runtime will be less extensive, so it will still be in closed beta.

Privacy Sandbox for Android

Cross-app identifiers and covert tracking are replaced with API mechanisms including “Attribution Reporting,” “Topics,” and “FLEDGE” in the Privacy Sandbox for Android.

The Topics API functions as a classifier model that determines user interests based on app activity and notifies advertisers appropriately.

The top 5 topics are chosen from a list of thousands after the user interests are calculated weekly using data from the device.

FLEDGE is a further component of the Privacy Sandbox that includes the Custom Audience and Ad Selection APIs.

While the latter gives publishers the option to identify target audiences based on interests, ad selection gives advertisers information on which ads performed well on a given device, enabling them to render the right one.

Buyers Creates custom Audiences

Together, these APIs eliminate the long-standing Android advertising IDs that can potentially be used to track users.

Third-party advertising code will be segregated by the SDK Runtime, preventing the apps from including it any longer. User interest indicators and other marketing-related data won’t be available to them.

Privacy Sandbox has come under fire from DuckDuckGo for being a pretentious system that does nothing more than give indirect user tracking new names.

Furthermore, Brave claims that the Privacy System forces Google centralization while only achieving small privacy advances at the price of user choice.

Google is continuing with its plan to roll out the new system across all of its products, including Chrome and Android, in spite of these criticisms.

The tech behemoth also pledges to keep considering complaints and feedback in order to target interventions to specific issues.

Time to run

A crucial part of developing apps and software is using third-party SDKs.

Without having to write any code themselves, developers may add features and functionality to their apps, such as monetization, analytics, and crash reporting.

However, after being integrated into an app, certain SDK providers may utilize that access to gather and share data with other third parties in an unrestricted manner. Apps have been removed from the App Store as a result of bad behavior on the part of some SDKs.

The Android Privacy Sandbox’s SDK Runtime API separates an SDK’s code execution from the rest of the app, effectively preventing it from collecting in-app data without explicit consent.

Although this feature will primarily impact what one might consider to be the underbelly of the industry, it will also have an impact on larger companies that sell SDKs.

What about the ironSource SDK, which is currently owned by Unity, or AppLovin’s MAX SDK for mobile mediation, for instance?

Google Ad ID

What will become of the Google Ad ID?

The vice president of product management for Android security and privacy at Google, Anthony Chavez, made a commitment in February to “support existing ad platform features, including Ad ID, for at least two years” and to “provide substantial notice ahead of any further changes,” despite the fact that Google has refrained from stating that it will eliminate its advertising ID.

It’s alluring to try to interpret things in another way.

Supporting something “for at least two years” begs the question: What happens after the two years are up? There is just over a year left on that clock.


Google is urging developers to test the fixes in the Android Privacy Sandbox and give their comments in the interim.

Earlier this year, Google published a number of developer previews of the Android Privacy Sandbox in order to gather early input, which it then incorporated into the APIs that are currently available for wider developer testing.

A registration and authentication process is required for developers and ad tech firms who want to test the Android versions of Topics, FLEDGE, and the reporting attribution API. To sign up for the beta early tester program, they will also need to complete a form.

SDK Runtime, however, will continue to be in closed beta for a few projects. Companies that are interested in giving it a try must submit a separate application.


Google’s Android Privacy Sandbox attempts to reduce user tracking while providing marketers with practical performance-measuring options. Starting in the first few months of 2019, the system will be rolled out to Android 13 mobile devices. Developers are urged to register in order to access the system’s APIs and begin developing their integrations. The SDK Runtime API of the Android Privacy Sandbox divides the code execution of an app from the rest of the app, essentially prohibiting it from gathering in-app data without explicit agreement. A number of developers’ improper actions have led to the removal of apps from the App Store.

To test the updates in the Android Privacy Sandbox, Google is urging developers. Developers and ad tech companies need to go through a registration and authentication process.

What is privacy sandbox Android?

The Android Privacy Sandbox is designed to significantly improve privacy for the ecosystem without compromising essential ad functionality or jeopardizing the availability of free ad-supported apps.

What is the privacy sandbox on my phone?

Android’s Privacy Sandbox will protect privacy while giving app developers the resources they need to run and expand their companies. In addition to limiting data sharing with other parties, it will develop new solutions that work without cross-app identifiers, such as Advertising ID.

Does Android have a sandbox?

The Android architecture separates apps from one another and shields them against intrusive software and harmful apps. To build a kernel-level sandbox, Android gives each application a distinct user ID (UID). At the process level, this kernel guarantees security between apps and the system.

Should I turn on the Sandbox?

The concept that the Web is first and foremost for people will be undermined by the Privacy Sandbox. These guiding principles—that the Web should put users first and provide them power and control—are outlined in key W3C documents.
