## Expo installation

> This package cannot be used in the "Expo Go" app because [it requires custom native code](https://docs.expo.io/workflow/customizing/).

First install the package with yarn, npm, or [`npx expo install`](https://docs.expo.io/workflow/expo-cli/#expo-install).

```sh
npx expo install expo-privacy-manifest-polyfill-plugin
```

After installing this npm package, add the [config plugin](https://docs.expo.io/guides/config-plugins/) to the [`plugins`](https://docs.expo.io/versions/latest/config/app/#plugins) array of your `app.json` or `app.config.js`:

```json
{
  "expo": {
    "plugins": ["expo-privacy-manifest-polyfill-plugin"]
  }
}
```

Next, rebuild your app as described in the ["Adding custom native code"](https://docs.expo.io/workflow/customizing/) guide.

  "expo": {
    "name": "My App",
