Hand and Body Privacy Notice

Effective November 1, 2023

We collect and retain certain data from your device to provide hand and body tracking and ensure it works properly, consistent with our Supplemental Meta Platforms Technologies Privacy Policy.

For hand and body tracking, our software analyzes images of your hands and body from the cameras on your headset to estimate the location of certain key points on your hands and body (such as your knuckles, arms, legs and torso). All of this analysis is done on your device in real time as you move, and the images and estimated points are deleted in real time after processing. We do not collect or store this data on Meta servers.

The software fits a generic hand and body model over the estimated points on your hands and body, resulting in estimated body scale data (which estimates the proportion of certain parts of your body to the generic body model), estimated hand size (represented by standardized numerical values such as between 0.5 and 1.5), and estimated hand and body pose data (such as approximate position and orientation of fingers and body parts).

Estimated body scale and estimated hand and body pose data are processed on your device or Meta servers (e.g., the data may be processed on Meta servers to animate your avatar’s movements in a multiplayer scenario), and are continuously generated and overwritten in real time as they provide hand and body tracking.

Estimated hand size data is also processed on device or on Meta servers. It is generated every time you put on your headset and start using hand and body tracking. We store estimated hand size data on our servers to ensure hand and body tracking works properly; this data will be deleted within 90 days, when no longer needed for that purpose. Estimated hand size data may be stored on your device to provide you with a more consistent experience across play sessions. If estimated hand size data is stored on your device, the device will be programmed to delete the data within three years, or if you choose to turn off storage, whichever occurs first. Unless storage is on, estimated hand size data will be deleted from your device at the end of each play session.

Since estimated body scale, estimated hand size, and estimated hand and body pose data (collectively, “abstracted hand and body data”) is based on generic models and standardized numerical values, it is not unique to you. For example, your estimated hand size might be “1”, and many other people would have that same estimated hand size.

On Meta Quest Pro, Meta Quest 2, and earlier devices, our software may process only a subset of this hand and body tracking data (e.g., only data about your hands) due to system limitations.

If another person uses your account on your Meta Quest devices, and uses hand and body tracking, the raw hand and body images, estimated points on hands and body, and abstracted hand and body data from such person may also be processed unless they turn off hand and body tracking. You can permit other people to use hand and body tracking through your account only if they have enabled it through their accounts or if you are their legally authorized representative.

We also collect and retain your usage data, image telemetry (e.g., exposure, contrast), and other information about your interactions with hand and body tracking, such as tracking quality, the amount of time it takes to detect your hands and body, and the number of gestures you make. If you have chosen to share additional data with Meta, we collect additional data about how you use your headset (including hand and body tracking) to help Meta better personalize your experiences and improve Meta Quest (Learn More). The data described in this paragraph is sent to and stored on our servers and will be disassociated from your account when we no longer need it to provide the service or improve hand and body tracking. If you delete your account, the data associated with your account will be deleted or disassociated from your account.

If your device crashes, we send crash logs about your device to our servers, which may contain recently generated estimated body scale and estimated hand and body pose data as well as other information about your interactions with hand and body tracking, consistent with our Privacy Policy. This data is stored on Meta servers until no longer necessary to provide hand and body tracking or until your account is deleted - whichever comes first.

Hand and Body Tracking in Applications

When you choose to use an application from the Meta Horizon Store that supports hand and body trackinge, the app will collect your abstracted hand and body data. If you use an app offered by Meta, the app will use this data consistent with this Privacy Notice and our Privacy Policy. If you use a third party app, the app will process your abstracted hand and body data in accordance with the app developers' privacy policies. App developers are permitted to use this data only for purposes outlined in the Developer Data Use Policy, which describes how developers must handle user data. But we do not control how a third party app uses, stores, or shares your abstracted hand and body data. Please read the developers' privacy policies to understand how they process your data. See also our Privacy Policy for more information about how third parties access your data.

Hand and Body Tracking on Websites

When you choose to visit a third party website that supports hand and body tracking, the website may collect your estimated hand and body pose data. You will receive a notice when you visit a website that requests access to this data, and you can decline the request. Meta does not control how third party websites use, store, or share your estimated hand and body pose data once they collect it, so you should only allow access to this data by websites that you trust.
