The Privacy Sandbox on
Android
introduces new technologies to improve user privacy and enable effective,
personalized advertising experiences for mobile apps. The Privacy Sandbox
includes Privacy-Preserving
APIs,
each of which requires an Ad Services normal permission in order to support
core advertising use cases without reliance on cross-app identifiers.
The Topics
API
is part of the Privacy Sandbox designed to infer coarse-grained interest signals
on-device based on a user's app usage. These signals or "topics" are
recognizable categories that are inferred based on the apps they used.
Apps and advertising platforms can use topics to decide what ads are relevant.
Topics support interest-based advertising (IBA) use cases without requiring
tracking of individual users across mobile apps.
Google Mobile Ads SDK
22.4.0 accesses the Topics API and declares
the following permission by default:

Android's instructions.
Attribution Reporting API (with debug reports)
The Attribution Reporting
API
is part of the Privacy Sandbox and is designed to provide improved user privacy
by removing reliance on cross-party user identifiers and to support key use
cases for attribution and conversion measurement across mobile apps.
Google Mobile Ads SDK
22.4.0 accesses the Attribution Reporting API with
debugging reports and declares the
following permissions by default:
