Airspace Explorer — Privacy Policy

Last updated: 16 June 2026

Airspace Explorer is a macOS application developed by freethinker AG (“we,” “us”). We designed it to do its job without collecting your personal data. This policy explains what that means in practice.

The short version

Airspace Explorer does not collect, store, transmit, or sell any personal information. There are no user accounts, no analytics, no advertising, no tracking, and no third-party tracking SDKs. The app does not access your location, contacts, camera, or microphone.

Data stored on your device

All of your settings and the list of airspace sources you configure are stored locally on your Mac (in the app’s Application Support folder) and in the macOS user defaults for the app. This information never leaves your device through us, and we have no access to it.

Network connections

To provide its features, the app makes outbound requests directly from your Mac to third-party servers that we do not operate:

Terrain elevation data. When you use the 3D view, the app downloads public elevation tiles from the Terrarium dataset hosted on Amazon Web Services (s3.amazonaws.com/elevation-tiles-prod).

Airspace files. When you load an airspace source, the app downloads the corresponding OpenAir file from its web address — either an entry from the built-in catalog or a URL you add yourself.

As with any internet request, the operators of those servers may automatically receive standard technical information such as your IP address and the file requested. This data is handled by those third parties under their own privacy policies and is not collected by, sent to, or accessible to us. We do not add any identifiers to these requests.

Children’s privacy

The app is not directed at children and collects no data from anyone, including children under 13.

Changes to this policy

If we change this policy, we will update the “Last updated” date above and post the revised version at this address.
