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.
Learn more about Android's Privacy Sandbox initiative and
Ad Manager.
Topics API
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.
Next Gen Mobile Ads SDK
accesses the Topics API and declares
the following permission by default:
<!-- Topics API permission. -->
<uses-permission android:name="android.permission.ACCESS_ADSERVICES_TOPICS" />
If you want to opt out of Ad Manager testing of Android's Topics API,
see how to prevent the merging of permissions in
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.
Next Gen Mobile Ads SDK 22.4.0 accesses the Attribution Reporting API with
debugging reports and declares the
following permissions by default:
<!-- Attribution Reporting API (with debug reports) permissions. -->
<uses-permission android:name="android.permission.ACCESS_ADSERVICES_ATTRIBUTION" />
<uses-permission android:name="android.permission.ACCESS_ADSERVICES_AD_ID" />
If you want to opt out of Ad Manager testing of Android's Attribution
Reporting API, see how to prevent the merging of permissions in
Android's instructions.
