Data and privacySources, and what stays on your device
Monitor readings and model forecasts are shown separately. The AQI in Saans is indicative: it follows the CPCB method (24-hour averages, 8 hours for O₃ and CO, highest sub-index) on CAMS model data, with PM corrected by nearby monitors or CPCB-anchored monthly factors. It is not the official CPCB National AQI. Delhi ward forecasts come from a graph neural network trained on CPCB stations. Wind, mixing height and past weather come from Open-Meteo (ERA5 for history); fire hotspots come from NASA FIRMS satellites. Maps use OpenStreetMap tiles; trip routes come from OSRM. Your name, onboarding answers, conditions and challenge streak stay in this browser. If you sign up for alerts, your email, place, profile answers and conditions are stored with Saans on AWS only to write those emails; every email has an unsubscribe link.
