Data
Open-Meteo for air, UV, and weather. Place names from Nominatim / OpenStreetMap. We show which AQI signal you see and how fresh it is.
Data confidence
About input quality—not whether outdoors is safe for you. Thin data means softer guidance.
Privacy
Location stays in-session for API calls. See Legal.
