Aircraft Overhead is a Chrome extension that detects aircraft flying over a user-defined home location using public flight tracking APIs and displays them in a real-time radar popup.
None. The developer does not collect, receive, or store any data from users. There are no servers, no databases, and no analytics operated by this extension.
All data — including your home coordinates, detection settings, OpenSky credentials, and today's flight history — is stored exclusively on your own device using Chrome's local storage (chrome.storage.local).
Your coordinates are either entered manually or detected once via the browser's geolocation API when you click "Use my location" in Settings. They are stored only on your device and are never transmitted to the developer or any third party beyond the flight data requests described below.
The extension makes outbound requests to these services to fetch flight and map data. Each receives the minimum data necessary:
Receives your latitude, longitude, and search radius (in nautical miles) to return a list of nearby aircraft. No account or personal identifiers are sent.
Receives a bounding box or aircraft identifier to look up route data (origin and destination airports). If you optionally provide OpenSky credentials in Settings, they are stored locally on your device and transmitted only to OpenSky's API over HTTPS for authentication. OpenSky's own privacy policy applies.
Receives standard map tile requests (zoom level and tile coordinates) to render the radar background map. No personal data is included in these requests.
This extension does not load or execute any remotely hosted code. All JavaScript runs locally from within the installed extension package.
This extension does not knowingly collect any information from anyone, including children under 13.
If this policy changes, the updated version will be posted at this URL with a revised date.
