Privacy policy

Last updated 2026-07-30.

The DETENT app collects no personal data. There is no account to create, no analytics SDK, and no tracking of any kind in the app.

Every message the app sends stays on your own local network. DETENT talks directly to the bridge you run on your PC, over a plain WebSocket connection between your phone or tablet and that PC. Nothing about your flights, your radios, or your device is sent anywhere else, and there is no server operated by us in between.

The app uses your camera for one purpose: scanning the pairing QR code the bridge shows on your PC, so the app can connect to it. Camera frames are processed on your device only, to find that QR code, and are never stored or transmitted.

The airport and frequency database is bundled with the app and works entirely offline. It comes from OurAirports, a public domain dataset. Looking up an airport does not contact any server.

This website. Separately from the app, flydetent.com uses Cloudflare Web Analytics to see basic, aggregate traffic, like how many people visit which pages. It is cookieless and privacy-preserving: it sets no cookies, builds no profile, does not track you across sites, and collects no personal data or fingerprints. It tells us nothing about you as an individual, and it has no connection to the app, which still sends nothing off your local network.
