Google to Roll Out Privacy Sandbox Beta on Android 13 by Early 2023

Internet behemoth Google on Tuesday said it plans to roll out
Privacy Sandbox for Android in beta to mobile devices running
Android 13 starting early next year.

“The Privacy Sandbox Beta will be available for ad tech and app
developers who wish to test the ads-related APIs as part of their
solutions,” the company said^[1].

To that end, developers will need to complete an enrollment
process in order to utilize the ads-related APIs, including
Topics^[2], FLEDGE^[3], and Attribution Reporting^[4].

Topics, which replaced^[5]
Federated Learning of Cohorts (FLoC) earlier this year, aims to
categorize user interests under different “topics” based on their
device web browsing history. These inferred interests are then
shared with marketers to serve targeted ads.

FLEDGE and Attribution reporting, on the other hand, enable
custom audience targeting and help measure ad conversions^[6]
without relying on cross-party user identifiers, respectively.

Organizations can also request access for a limited number of
devices to test the Beta, plus register any apps which will utilize
the Privacy Sandbox APIs.

The development comes after the search and advertising giant
expanded^[7]
the initiative to include its mobile operating system in February
2022, and followed it up with a developer preview^[8]
in May 2022.

Privacy Sandbox is an effort^[9]
led by Google to create a set of web standards for websites to
access user information without compromising on privacy. It aims to
facilitate online advertising without resorting to invasive methods
like third-party tracking cookies or fingerprinting.

That said, the company’s plans to turn off third-party cookies
in the Chrome web browser have been delayed^[10] twice^[11], with the technology
now expected to be phased out sometime in the second half of
2024.

To complicate matters further, the proposals have drawn
criticism from rival browser vendors like Mozilla Firefox^[12] and developers of other
Chromium-based browsers such as Brave, Opera, and Vivaldi, who have
said the newer methods^[13] would cement “Google’s
position as a web monopolist.”

DuckDuckGo, which blocks Privacy Sandbox through its Chrome
browser extension as of May 2022, said Topics allows Google to
surveil users’ online activities and share that information with
advertisers for behavioral targeting without their consent.

“This targeting, regardless of how it’s done, enables
manipulation (ex. exploiting personal vulnerabilities),
discrimination (ex. people not seeing job opportunities based on
personal profiles), and filter bubbles (ex. creating echo chambers
that can divide people) that many people would like to avoid,” the
company noted^[14].

Despite the pushback, Google said it’s looking to engage with
the broader ecosystem and gather “continued feedback as we enter
this next phase of testing.”
