Privacy Policy


This Privacy Policy describes how your personal information is handled in GST[AR] for iOS.

We Collect No Personal Information Using Our Application

We do not collect, use, save, or have access to any of your personal data recorded in GST[AR] for iOS.
Individual settings related to the GST[AR] app are not personal and are stored only on your device.
You will be asked to provide access to your camera. This is required to place geological models in augmented reality and is essential for the core functionality of the app. We do not have any access to or save any captured footage.
Furthermore, we ask for local network access. This access will be used to enable collaboration via peer-to-peer connections with other devices. If you do not want to use any collaborative features, you do not have to grant the permission for this to use this app. Your phone will only advertise its name to other instances of GST[AR] if you want to share a collaborative session. During a collaborative session, only information about the session is exchanged locally between devices. No model or session data will be transmitted over a server.
A user is able to store an URL pointing to an endpoint providing data and models to the app. This information will be stored on device and is never transmitted to us or a remote server. This URL might be transmitted locally to other devices joining a collaborative session created from the device on which the URL is stored. This is required for all peers of the collaborative session to access the model data.

Our Application Complies with the Children’s Online Privacy Protection Act

Our application does not collect personal information from anyone, including children under the age of 13.
