SmokySignal is a personal/hobby project. The information shown is derived from public ADS-B telemetry — no private feeds, no enforcement-tier sources.
Aircraft positions come from adsb.fi (primary) and OpenSky Network (fallback / historical). Both are anonymous and require attribution, provided here and in the app footer.
The tail registry is built from publicly available state and county fleet records. If you spot a wrong tail or a misclassified aircraft, email feedback@smokysignal.app.
No warranty. Don’t use this app to evade enforcement — that isn’t the point. Knowing the bird is up is the same as seeing a marked patrol car ahead: ride within the limit and ride well.
