Privacy Policy for
Air Quality Index

This Privacy Policy governs your use of Air Quality Index ("App", "Service"), a real-time air quality monitoring and weather application created and developed by AppAspect Technologies Pvt. Ltd. ("we", "us", or "our"). The App is available on both the Google Play Store (Android) and the Apple App Store (iOS) and is designed to help users monitor air pollution levels, track key pollutants, view weather conditions, and make informed health and travel decisions.

By downloading, installing, or using the App on either platform, you agree to the terms of this Privacy Policy. If you do not agree, please do not use the App.

Air Quality Index is a comprehensive environmental monitoring companion available on both Android and iOS that keeps you informed about the air you breathe and the weather around you.

The App uses the standard Air Quality Index scale on both platforms to categorise pollution levels and provide health guidance.

Air Quality Index requests the following permissions on each platform. All permissions are used only for the stated purpose and can be reviewed or revoked at any time in your device settings.

The table below summarises every category of data the App may collect across both platforms:

Air Quality Index does not collect personal information on either platform. There is no account creation, no login, no registration, and no collection of names, email addresses, or any personally identifying data through the App.

The App automatically collects limited non-personal, non-identifiable information to improve performance and serve advertisements:

• Device model, OS version, and device language.
• Android: Google Advertising ID (GAID) — resettable device-level identifier used by AdMob.
  iOS: Apple Identifier for Advertisers (IDFA) — subject to App Tracking Transparency (ATT) consent on iOS 14.5+.
• App activity: city searches, AQI categories viewed, features accessed, session duration (anonymised via Firebase Analytics).
• Android: ANR (Application Not Responding) reports and crash logs.
  iOS: Crash logs and diagnostic data (via Firebase Crashlytics).
• General geographic region (derived from location) included in analytics data.
• IP address used to connect your device to the internet (used by data APIs and ad networks).
• Favourite places saved locally on your device — not transmitted to our servers.

Location is the primary data point this App uses to deliver its core value — on both Android and iOS. Here is exactly how your location is used:

• Automatic local AQI detection — your GPS coordinates are sent to our AQI data providers to find the nearest monitoring station and display current pollution levels.
• Local weather conditions — your location is used to fetch temperature, humidity, wind speed, and weekly weather forecasts.
• Map view — your coordinates determine the initial map centre, showing AQI levels for nearby cities with colour-coded overlays.
• Nearby city discovery — your coordinates are used to suggest AQI data for cities in your vicinity.
• Analytics region data — a general geographic region (not precise GPS) is included in anonymised Firebase Analytics reports.
• Ad delivery — general location may be used by Google AdMob to serve geographically relevant advertisements on both platforms.

Air Quality Index aggregates environmental data from trusted third-party data providers and monitoring networks on both platforms. We do not generate or own the AQI or weather data displayed in the App. All data is sourced in real time from external APIs and monitoring stations. By using the App, you acknowledge that:

• AQI readings are real-time estimates and may differ from official government monitoring stations.
• Data availability and accuracy depend on the density of monitoring stations in your area.
• Your location coordinates are transmitted to these data providers to retrieve relevant local data on both Android and iOS.
• These data providers operate under their own privacy policies and terms of service.

Air Quality Index is a free application supported by advertisements via Google AdMob on both Android and iOS. AdMob uses a platform-specific advertising identifier to serve relevant ads.

• Android — GAID: Resettable Google Advertising ID for ad personalisation.
• iOS — IDFA: Apple's Identifier for Advertisers, used only after ATT permission is granted on iOS 14.5+.
• Device model, OS version, and language for contextual ad targeting.
• General location for geographically relevant advertisements.
• Ad impression and click interaction events.

No specific AQI readings, pollutant data, or health-related information about your location is used for ad targeting on either platform.

We use Google Firebase Analytics and Firebase Crashlytics on both platforms to understand how users interact with the App and to fix stability issues. No personal data is included.

Firebase Analytics collects: app events (city searches, features accessed), screen views, session duration, device model, OS version, app version, and general geographic region. Firebase Crashlytics collects: crash stack traces, ANR reports (Android) / crash diagnostics (iOS), and device state at crash time. All data is anonymised. By using the App, you accept the Firebase Analytics Terms.

Air Quality Index integrates the following trusted third-party services across both Android and iOS. Your location is shared with AQI and weather data providers and the mapping service to deliver the App's core functionality.

The App uses platform-specific resettable advertising identifiers for ad delivery. These are not linked to your personal identity.

We implement commercially reasonable safeguards on both platforms:

• HTTPS / TLS encryption for all data transmitted between the App and external AQI, weather, mapping, analytics, and advertising services.
• Local-only storage for favourite places and preferences — stored in the platform's private app storage, inaccessible to other apps.
• Platform sandbox security — both Android and iOS isolate the App's data from other applications.
• Transactional location use — location coordinates are used only for the duration of the API request and are not retained by us after the response is returned.
• iOS Keychain — sensitive tokens on iOS are stored in the hardware-backed Keychain.

Air Quality Index is a general environmental information application available on both platforms. The App does not collect personal information. However, the App does share location data with third-party AQI and weather data services — parents and guardians should be aware of this when allowing children to use the App.

For family use: Android — manage location permissions via Google Family Link. iOS — use Screen Time parental controls and deny the ATT prompt. On both platforms, children can use the manual City Selector to browse AQI data worldwide without granting location permission.

We do not knowingly collect personal information from children under 13 on either platform.

We may update this Privacy Policy from time to time. When we make material changes, we will update the Effective Date at the top of this page and may notify you via an in-app notice on either platform. Continued use of the App after an update constitutes your acceptance of the revised policy.

For any questions, concerns, or privacy-related enquiries, please contact us.
