Data & methodology

We keep this simple on purpose: one live data source, nothing stored on our end, and plain definitions for the numbers on your dashboard.

📡
Live data source
Conditions come from WeatherAPI.com, refreshed roughly every 10 minutes per pinned city. Hit "Refresh" any time to force a new pull.
🔒
Your data stays on your device
Pinned cities are saved in your browser's local storage only. There's no account system, so we never see or log which locations you're checking.
📊
Reading the numbers
AQI ranks how safe the air is to breathe, from Good to Hazardous. Pressure (hPa) measures atmospheric weight — falling pressure usually signals a change in weather is on its way.
