Privacy Policy

Last updated: October 29, 2026

The short version

Niner collects no personal data. There is no account, no analytics, no advertising, and no tracking of any kind.

What stays on your phone

Your station list, cached reports, and the unlock flag are stored only on your iPhone. Deleting the app deletes them.

The requests the app makes

To fetch a report, Niner asks aviationweather.gov (a US government service run by NOAA) for the METAR and TAF of a station. That request contains the station's ICAO code and nothing else about you. NOAA's own privacy policy applies to its servers. Niner is not affiliated with or endorsed by NOAA.

Nearby airports and your location

If you tap Nearby, Niner asks for your location once, with your permission. It sends NOAA only a rough area about 60 miles wide, snapped to a coarse grid, to list the stations inside it. Your exact position stays on the phone, is used only to sort that list by distance, and is never stored or sent anywhere. Typing a station code works with location off.

The one-time purchase

Niner Unlimited is handled entirely by Apple's App Store under Apple's privacy policy. Niner only stores a local flag that the unlock was bought, so it keeps working offline.

What we don't do

We don't collect usage statistics, crash reports, identifiers, or location. We don't sell or share data. There is no data to sell or share.
