Air Today — Effective October 25, 2026
Air Today is an ambient air quality app for iPhone and Apple Watch developed by Owen McLoughlin. This privacy policy explains what information the app accesses, how it is used, and your choices regarding that information.
Air Today does not collect any personal data. The app does not require an account, does not use analytics or tracking frameworks, and does not serve advertisements.
The app may access the following information on your device:
Your location, when provided, is used solely to request air quality data for the area near you: station readings from the World Air Quality Index (WAQI) API, and estimates, forecasts and weather from the Open-Meteo API (with the coordinates rounded to about 1 km). The location is sent directly from your device as part of each data request — it does not pass through any server owned or operated by the developer.
To show the name of your town, your device asks Apple Maps for the place at your location. Apple handles that request under Apple's privacy policy.
Saved locations, preferences and your health profile are stored on-device using standard iOS storage. Data is shared between the app, its widgets and Apple Watch app through an App Group container, and between your iPhone and Apple Watch using Apple's WatchConnectivity — directly between your own devices. The coordinates of your last check are kept on your device so widgets and background updates can stay current.
Widgets and complications read data stored on your device. When it is more than an hour old, they request a fresh reading in the same way the app does.
Notifications (the daily verdict, air-quality alerts, best-time and spike alerts) are created on your device from data the app has fetched. Air Today does not use a push notification server.
Siri and Shortcuts: when you ask Siri about the air, Air Today answers using the same data as the app. Siri requests are handled by Apple under Apple's privacy policy.
Air Today uses the World Air Quality Index (WAQI) API to retrieve air quality data. When the app fetches air quality information, it sends a network request that includes the coordinates or name of the location you are viewing. This request goes directly from your device to the WAQI service.
The WAQI API is operated by the World Air Quality Index project. Their use of data is governed by their own privacy policy, available at aqicn.org/privacy.
Air Today also uses the Open-Meteo air quality and weather APIs, whose air quality data comes from the Copernicus Atmosphere Monitoring Service (CAMS). These requests include the location you are viewing, rounded to about 1 km, and go directly from your device to Open-Meteo. Open-Meteo states that its server logs, which can include request coordinates, are not shared and are deleted after 90 days; see open-meteo.com/en/terms.
Air Today does not integrate any other third-party services, SDKs, analytics platforms, or advertising networks.
Since no personal data is collected or transmitted to the developer, there is nothing to retain on our end. Data stored locally on your devices (saved locations, preferences, health profile) persists until you change it within the app or uninstall the app.
Air Today does not share your data with anyone. There is no server-side storage, no user database, and no data broker relationships. Your information stays on your device.
Air Today does not knowingly collect personal information from children under 13 (or the applicable age in your jurisdiction). Since the app does not collect personal data from any user, it is safe for use by people of all ages.
If this privacy policy is updated, the revised version will be posted at this URL with an updated effective date. Because the app does not collect contact information, we cannot notify you directly of changes — we encourage you to review this page periodically.
