## What is DeepBreath?

DeepBreath helps you quickly find indoor places with clean air during heavy pollution days.

WHY YOU NEED THIS APP
During smoggy days, it's hard for children to stay home all day. Many large shopping malls are equipped with Dedicated Outdoor Air Systems (DOAS) that effectively filter PM2.5 and PM10 particles. DeepBreath helps parents find these indoor spaces with excellent air quality, so children can play safely.

FEATURES
- Outdoor Air Quality Map - View real-time air pollution levels at your location. Data updates daily at noon.
- Indoor Air Quality Map - Tap the switch button in the top-right corner to see indoor PM2.5 levels at nearby malls. Green markers indicate places with good air quality.
- Mall Details - Tap any mall marker on the map to view its name, address, and latest air quality data.
- Air Quality Ranking - Tap the menu in the top-left corner to see all nearby malls sorted by PM2.5 levels. Quickly find the cleanest indoor spaces.

FOR MALL MANAGERS
Shopping mall managers can register to upload real-time photos and data from their PM2.5 monitors. All data is valid for 48 hours to ensure freshness and accuracy.

DATA SOURCES
- Outdoor data: IQAir professional monitoring stations
- Indoor data: Uploaded by mall managers, automatically verified

PRIVACY
- Location is only accessed while using the app
- We do not store or track your personal location data

Help every family find a safe place to breathe.
