Data Collection

The libraries cardboard and cardboard-xr-plugin do not collect any data. However, when a QR code is recognized during scanning as requested by the developer, these libraries may make multiple web requests to retrieve the Cardboard viewer device parameters.


See (Android) and (iOS) for the code that does the above.

Brand guidelines

The "Google Cardboard" name is a trademark owned by Google and is not included within the assets licensed under the Apache License 2.0. Cardboard is a free and open-source SDK that developers can use to create apps that are compatible with the Google Cardboard VR platform. At the same time, it's important to make sure that people don't use the "Google Cardboard" mark in ways that could create confusion.

The guidelines below are designed to clarify the permitted uses of the "Google Cardboard" mark.

Things you can do:

  • Use the "Google Cardboard" mark to describe or refer to apps developed with the Cardboard SDK in ways that would be considered "fair use."
  • Use the "Google Cardboard" mark to make truthful factual statements regarding the compatibility or interoperability of your app. For example, "This app is compatible with Google Cardboard" or "This app works with Google Cardboard."

Things you can't do:

  • Don't use the "Google Cardboard" mark in a manner that implies that Google has endorsed or authorized your app or that makes your app appear to be an official Google product. For example, you shouldn't reference your product as "an official Google Cardboard app."
  • Don't incorporate the "Google Cardboard" mark into your own product names, service names, trademarks, logos, or company names.
  • Don't display the "Google Cardboard" mark in a manner that is misleading, unfair, defamatory, infringing, libelous, disparaging, obscene or otherwise objectionable to Google.
  • Don't alter or distort the "Google Cardboard" mark. This includes modifying the mark through hyphenation, combination or abbreviation. For example, don't say "G Cardboard" or "Google-Cardboard."

In addition to these guidelines, please ensure that you follow the trademark usage guidelines available here:
