1. Information We Collect
Information you provide
- This app does not collect personal information. There is no sign-up or login.
Automatically collected
- Advertising identifier (IDFA): used by Google AdMob to serve ads (only if you allow ATT).
2. How Information Is Used
| Data | Purpose | Stored |
|---|
| Selected monitoring station, last reading | Show air-quality info / widget | On-device, locally |
| Location (optional) | Auto-select the nearest monitoring station | Used on-device only, never stored |
| Advertising identifier | Serve Google AdMob ads | Google servers |
3. Location Handling
- Location permission is optional. If you decline, you can still pick a monitoring station manually and use the app fully.
- Your location is used once, only at the moment you ask the app to find the nearest station. It is never stored in the app or sent to our own servers.
- To convert coordinates into an address, Apple's geocoding service may be called from your device.
- Only the station name — never your coordinates — is sent to the air-quality API.
4. Data Storage & Security
- The selected station and last reading are stored only in local on-device storage (shared between the app and its widget).
- The app does not send usage data to our own servers. (We operate no backend.)
- Air-quality data is fetched from the Korea Environment Corporation Air Korea public API (data.go.kr) and cached for 15 minutes to avoid excessive requests.
- Network requests may occur to Google AdMob to display ads.
5. Third-Party Services
| Service | Purpose | Privacy Policy |
|---|
| Korea Environment Corporation Air Korea (data.go.kr) | Air-quality readings (only the station name is sent) | Open Data Portal |
| Apple Geocoding | Coordinates → address conversion (when auto-selecting a station) | Apple Privacy Policy |
| Google AdMob | Ads (banner) | Google Privacy Policy |
Overseas Transfer of Personal Data
To serve ads, this app transfers personal data overseas as follows.
| Recipient | Country | Items | When & How | Purpose | Retention |
|---|
| Google LLC | United States | Advertising identifier (GAID/IDFA) | Sent over the network when requesting ads | Serve Google AdMob ads | Per Google's Privacy Policy |
This app uses public data from Korea Environment Corporation Air Korea (attribution — no derivatives).
6. Advertising
- We use the Google AdMob SDK to show a bottom banner ad.
- On iOS we request App Tracking Transparency (ATT) permission; you may decline and still use the app fully.
7. Children
This app is intended for a general audience and is not primarily directed at children under 13.

- Location: change anytime in Settings > 나가두돼? > Location.
