Pocket Avionics privacy policy

Effective 5 November 2026.

In short

Pocket Avionics collects nothing. Everything it measures and records stays on your device, and the Android app has no permission to use the internet.

Location

With your permission, Pocket Avionics uses your device’s location for ground speed, track, true heading, GPS altitude and the track in recordings. It is used on the device only and is never sent anywhere. The app works without it.

Pocket Avionics gets your location from your device’s location services, which on most Android phones are provided by Google Play services. How those services work, such as whether they use Wi-Fi and mobile networks to improve accuracy, is set in your device settings and covered by that provider’s privacy policy. In the web version, your browser provides your location, and its settings and privacy policy cover how.

Sensors

The rotation, motion and pressure sensors drive the instruments. Their readings are used on the device only.

Recordings and settings

Recorded flights and your settings are kept in the app’s private storage on your device. They are not backed up to the cloud. Uninstalling the app deletes them, and you can delete a recording at any time.

Sharing

A recording leaves your device only when you export it as CSV or GPX. The Android app hands it to the app you choose to share it with, and the web version saves it as a download. What happens to it after that is up to you and the app you give it to.

No accounts, ads or tracking

There are no accounts, advertising, analytics or crash reporting, and no data is sold or shared with anyone.

The web version

Pocket Avionics also runs in your browser, from https://avionics.cobblebench.app/, which is hosted on GitLab Pages. As with any website, GitLab receives ordinary request details when your browser loads it, and may keep them in its server logs: your IP address, the time and the pages requested. GitLab’s privacy statement is at https://about.gitlab.com/privacy/.

Everything the app needs, fonts included, comes from that site; nothing is loaded from any other server. After it has loaded, the app sends nothing: what it measures and records stays in your browser, and it is blocked from contacting anyone else. Your recordings, your settings and a copy of the app (so that it works offline) are kept in this site’s storage in your browser. Clearing this site’s data in your browser deletes them.

Children

Pocket Avionics is not directed at children.
