When starting an immersive web experience in Browser, you can choose to allow or block individual websites’ access to your hand and body tracking or spatial data.

Remember, Meta does not control how third party websites use, store, or share your data once hand tracking or spatial data permissions are granted, so you should only allow access to this data on websites that you trust.

Spatial data

What is Spatial data?

Spatial data refers to the information collected about the size, shape, and location of walls, surfaces, and objects in a physical space. Immersive web experiences that blend virtual and real-world environments use spatial data to understand the space around you and where you are within that space. You will receive a notice when you visit a website that requests access to spatial data, and you can decline the request. Learn more about spatial data.

What spatial data is shared with websites?

When you give a website permission to access your spatial data, you are giving access to:

• Scene data: Used to create a simplified model of a room and enables more physical awareness of a user’s surroundings. Without scene data, virtual objects cannot interact with physical objects.
• Mesh data:This allows the headset to understand the shape and structure of objects in a physical space. Without mesh data, virtual objects are not able to realistically interact with physical environments. Mesh data is only available on Quest 3 and Quest 3S headsets.
• Depth data: A rough approximation of the distance of real world objects from the headset. Websites can use this depth data to occlude graphics behind real world objects and render virtual objects in a way that feels three-dimensional. Depth data is only available on Meta Quest 3 and Quest 3S headsets.

Hand and body tracking data

What is hand and body tracking data?

Hand and body tracking is a feature for Meta Quest devices that allows you to switch between hands and controllers to interact with content in your headset. You have the choice to turn hand and body tracking on and off in Settings. Learn more about hand and body tracking.

What hand and body tracking data is shared with websites?

When you enable hand and body tracking and visit a third party immersive website that supports hand tracking features, your hand pose data and your estimated hand size may be shared with the website to improve your experience. You will receive a notice when you visit a website that requests access to hand and body data, and you can decline the request.

When using hand input on non-immersive (2D) websites that do not request access to hand and body tracking features, your hand pose data and estimated hand size are not shared with the website.

Managing website permissions

You will receive a notice when you use Browser to visit a website that requests access to spatial or hand and body tracking data. From the notice, you can decline or approve the permission request. To review or revoke permissions that have been given to a website:

Removing permissions does not delete or modify any data that a third-party website has already accessed.
