Google Releases First Developer Preview of Privacy Sandbox on Android 13

Google has officially released^[1]
the first developer preview for the Privacy Sandbox on
Android 13, offering an “early look” at the SDK Runtime and Topics
API to boost users’ privacy online.

“The Privacy Sandbox on Android Developer Preview program will
run over the course of 2022, with a beta release planned by the end
of the year,” the search giant said^[2]
in an overview.

A “multi-year effort,” Privacy Sandbox^[3]
on Android aims to create technologies that’s both
privacy-preserving as well as keep online content and services free
without having to resort to opaque methods of digital
advertising.

The idea is to limit sharing of user data with third-parties and
operate without cross-app identifiers, including advertising ID, a
unique, user-resettable string of letters and digits that can be
used to track users as they move between apps.

Google originally announced^[4]
its plans to bring Privacy Sandbox to Android earlier this
February, following the footsteps of Apple’s App Tracking
Transparency (ATT^[5]) framework.

Integral to the proposed initiative are two key solutions —

• SDK Runtime^[6], which runs third-party
  code in mobile apps such as software development kits (SDKs),
  including those for ads and analytics, in a dedicated sandbox,
  and

• Topics API^[7], which gleans
  “coarse-grained” interest signals^[8]
  on-device based on a user’s app usage that are then shared with
  advertisers to serve tailored ads without cross-site and cross-app
  tracking

To address criticisms that the model could possibly give Google
an unfair advantage, the tech behemoth noted that the
privacy-oriented systems will be developed as part of the Android
Open Source Project (AOSP^[9]) to ensure transparency
into the design and implementation of these solutions.

“Android will collaborate with the entire industry and app
ecosystem on the journey to a more privacy-first mobile platform,
and one which supports a rich diversity of value-exchange that
benefits users, developers, and advertisers,” the company said^[10].
