Privacy Policy

Privacy Policy for OpenAthena™ applications

Effective Date: 2024-03-29

Theta, the devlopers of the OpenAthena™ applications, (“we”, “us”, “our”) are committed to protecting the privacy of our users (“you”) while using OpenAthena (the “App”). This Privacy Policy outlines the types of information we collect, how we use that information, and the steps we take to protect your privacy.

1. Information We Collect

Since the App processes all data locally on your device, we do not collect or store any of your information. Data processed by the App remains on your device and is not transmitted to our servers.

The only instance where data is sent to a third party online is if you choose to use the automatic Digital Elevation Model download feature of our software. In such usage, only the latitude and longitude of your drone photo is used with the online OpenTopography API (Application Programming Interface) service to download an elevation model of the surrounding area.

OpenTopography’s privacy policy for this API is available in the link below. At the time of writing, OpenTopography’s policy indicates they collect only aggregated and anonymized usage data for standard operational purposes:

OpenTopography is based at the San Diego Supercomputer Center at the University of California San Diego, with operational support from the Division of Earth Sciences at the National Science Foundation. OpenTopography is unafilliated with us or our OpenAthena App.

2. Open Source Protects Your Rights

To protect your privacy, all the source code which defines how the App operates is open source, meaning anyone can inspect it. You have inalienable rights to view the source code of the App, download the App, and/or modify the App to your own specifications. You may (subject to local and international law) distribute the App with any modifications you have made, provided that you give your users the very same rights. These rights do not obligate users to make their systems available for inspection. Further details and limited restrictions on these rights are provided in the software license included with the App. These rights do not apply to proprietary modules sold by us for enhanced functionality with the App.

3. Cursor on Target Message

The App is designed to be compatible with other devices and applications on your local network. It is capable of sending a standard Cursor on Target message from your device to others on your local network. This only occurs if you explicitly trigger this action with a specific button press in the User Interface. This message contains the location of your target, the estimated accuracy of the target resolution, a serial number for the target resolution, and a partial, one-way hash of your device’s hostname. While the one-way hash is a unique identifier for your device, this hash process cannot be reversed to recover information about you or your device. The message solely serves to establish compatibility and enhance the functionality of the App in conjunction with other devices of you and your team connected with a local area network.

3. Data Security

We take the security of your data seriously. As all data processed by the App remains on your device (except for OpenTopography DEM download as noted in Article 1).

Your data is never transmitted to our servers, which minimizes the risk of unauthorized access or data breaches. It is your responsibility to protect your device from unauthorized access to ensure the security of your data.

4. Third-Party Services

Downloading the App on the Google Play or Apple App store will cause basic anonymized metrics about your usage to be collected by such storefront. The only third-party service for data processing is the OpenTopography API for automatic elevation model downloading (as indicated in Article 1). All other information processed by the App remains on your device and is not shared with any third parties.
