Should Google decide to discontinue support for the services and functionality provided by Cloud Anchors and the ARCore Cloud Anchor API introduced in ARCore 1.12.0, Google will announce this decision in the ARCore release notes and in What’s New in ARCore, and make commercially reasonable efforts to continue to operate these services for one year after that announcement.
However, Google may discontinue support earlier if it decides, in its reasonable good-faith judgment, that it is required to do so by law, third-party relationship, security risk, or substantial economic or material technical burden. Google makes no such commitment with respect to Cloud Anchors and the AR Cloud Anchor API as supported prior to ARCore 1.12.0, in which the device uploads the 3D feature map to the ARCore Cloud Anchor API.
