# Does Batch Push and In-App work on alternative app stores?

## Push <a href="#push" id="push"></a>

On Android, Batch relies on Google's push protocol, Firebase Cloud Messaging (FCM), to deliver push notifications to your users.

This means you can send push notifications to any devices that have recent **Google Play Services** installed, no matter where the app was installed (e.g. PlayStore, alternative store, standalone apk, etc).

For Huawei and Honor devices that do not include Google Play Services, Batch Push v1 relies on **Huawei Mobile Services.**

## In-App <a href="#in-app" id="in-app"></a>

In-App messages will be fully functional, regardless of the app store used to install your app or of any Google Play Services issues.
