Air Quality Router uses location coordinates to estimate nearby air quality and route readiness. Coordinates may be sent to Air Quality Router’s Cloudflare-based service for air-quality snapshot requests. The service limits provider access to the app and may cache air-quality responses from OpenAQ and CAMS / Copernicus ADS.
Data used for app functionality
The app may use precise or approximate location to compare route options near a selected route center. Air-quality responses are based on nearby OpenAQ readings or CAMS / Copernicus ADS forecast fallback data when recent readings are unavailable.
The app stores settings on device and uses iCloud key-value storage for shared Target AQI, availability, route centers and saved places, notification preferences, selection context, and recent route-readiness snapshots across the Apple app family. A route-readiness snapshot can include candidate planned-route geometry, the requested planning center, the resolved walking start, timing, estimated AQI, and source and freshness context. This continuity data remains in the signed-in Apple Account’s iCloud storage; Dot 1 Technologies VBA does not receive it through developer servers.
Guided walks, location, and Apple Health
Guided AQI-Aware Walk is optional and requires Plus, an eligible selected route, precise When In Use location, and permission to share and read Apple Health workout and workout-route records. Starter does not request Health permission.
During a guided walk, actual location fixes are processed on Apple Watch and passed to HealthKit to build the workout route. Air Quality Router does not create an app-managed workout history or app-managed iCloud workout record, transmit completed-route coordinates to Dot 1 Technologies VBA servers, the Cloudflare AQ Proxy, or air-quality providers, or include them in advertising or analytics. After a record is saved in Apple Health, Apple may store or synchronize it through iCloud according to Apple Account and Health settings. Apple Health controls storage, system synchronization, access, and deletion of the saved workout and route.
The separate guided-walk course package is transferred only between the paired iPhone and Apple Watch for staging and guidance; route-readiness snapshots described above are the app-managed iCloud continuity record. The Watch stores the guided-walk package in a protected, backup-excluded local file, and minimal recovery state contains no coordinates. The guided-walk package and recovery state are not sent through app-managed iCloud synchronization or to developer servers. When the route is replaced or expires, or the walk finishes or is discarded, the package is retired, the Watch file is deleted, and removal of any last paired-device transfer context is requested immediately or queued until the devices reconnect.
The Estimated Route AQI recap uses the AQI snapshot associated with the planned route at the start. It does not calculate exposure from the completed path.
Notifications and Calendar
Local notifications are scheduled on device from configured availability windows and route reminder preferences. A target-only notification can be selected so that no daily alert is sent unless the latest available route estimate is at or below Target AQI. Missing, stale, unavailable, or above-target data produces no target-only alert. Notification permission is required, and background preparation and delivery times are controlled by the operating system rather than guaranteed by Air Quality Router.
Calendar access is used for confirmed manual route event creation, scheduled-route display, and duplicate route-reminder avoidance. With Plus, you can turn on device-local automation on one iPhone or iPad. With notification permission and full Calendar access, automation checks timed availability across readable calendars for busy conflicts and writes a qualifying route event only to the selected writable calendar.
An Air Quality Router Calendar event can include route time, location or Maps context, and a saved estimated-AQI snapshot with source and freshness. The selected Calendar provider may store or synchronize those event details according to the Calendar account settings. Calendar information is processed on device and is not sent to the Cloudflare AQ Proxy, OpenAQ, CAMS / Copernicus ADS, or other external air-quality providers as Calendar data.
Diagnostics and support
Diagnostic logs remain local unless shared manually during support. Support requests may include information voluntarily provided in an email or support message.
Advertising and analytics
No advertising or third-party analytics are included in Air Quality Router.
App Privacy disclosure
Apple’s App Privacy information lists precise and approximate location as data used for app functionality. Health and Fitness data, including completed workout routes, remains in Apple Health and is not received by Dot 1 Technologies VBA. Information deliberately included in a support request is handled as described under Diagnostics and support.
