User Age Category package

Updated: Sep 4, 2026

The Platform SDK User Age Category Package lets your application retrieve a user’s age category, so it can tailor content and features accordingly. The categories are Child, Teenage (13-17), and Adult (18+).

The package returns a category; it does not itself make an application compliant. Use it as one input when building age-appropriate behavior for regimes such as COPPA and GDPR. The obligations remain the developer’s. It matters most for applications with user-generated content or social features.

Before you begin

Complete the prerequisite steps in Get Started Kotlin Development.

How to install

Add the following to your project’s ./gradle/libs.versions.toml file:

 [libraries]
 # Existing lines
 user-age-category-kotlin = { module = "com.meta.horizon.platform.sdk:user-age-category-kotlin", version.ref = "horizonPlatformSdk" }

 dependencies {
     // Existing lines
     implementation(libs.user.age.category.kotlin)
 }

In Android Studio, click File > Sync Project with Gradle Files to install the package.
Click Build > Generate App Bundles or APKs > Generate APKs.
In the “External Libraries” section of your project, confirm that these packages are listed.
```
 com.meta.horizon.platform.sdk:core-kotlin
 com.meta.horizon.platform.sdk:user-age-category-kotlin
```
Now you can initialize the Platform SDK and use User Age Category package functions in your app.

API reference

See the exact requests and responses in the Platform SDK User Age Category Package.

Test this on Meta Spatial Simulator

Test these APIs on Meta Spatial Simulator without a physical device. Sign in to the simulator first. When signed in, these APIs call the Meta backend and return real responses. When signed out, they return an authentication error rather than sample data.
