# How visual data powers shared AR experiences

With apps powered by Google's AR platform, ARCore, you can enjoy multiplayer or
collaborative AR experiences. To understand your physical environment, ARCore
uploads images from your device's camera to Google servers. These images are
processed to extract the visual data needed to allow multiple users to view and
interact with virtual objects in a shared physical space.

## What to know about data storage

- Images are automatically deleted after processing by Google servers.

- Visual data is securely stored on Google servers and isn't accessible to app
  developers.

- To enable shared experiences, apps are required to request camera permissions
  and to notify users that Google is processing visual data from the
  camera.

- No personally identifiable information is stored and shared experiences aren't
  linked to user accounts.
