Privacy Policy
This Privacy Policy explains how Kv Software ("we", "us", or "our") collects, uses, stores, and shares information when you use AirQ, also referred to as Airpollution on some platforms (the "App").
By using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with this policy, please do not use the App.
Information We Collect
The App is designed to show air quality information, nearby monitoring stations, saved stations, maps, and forecasts. To provide these features, the App may collect or process the following information:
- Location information: With your permission, the App may access your device location to find nearby air quality stations. If location permission is not granted or location services are unavailable, the App may use approximate IP-based location to provide nearby station results.
- Saved preferences: The App may store your selected language, favorite station IDs, nearest station ID, cached station information, and cached location information on your device.
- Usage and diagnostics data: Firebase Analytics and Firebase Crashlytics may collect app usage, crash reports, device information, operating system information, and diagnostic data to help us understand app performance and fix issues.
- Advertising data: Google AdMob may collect or use identifiers, device information, approximate location, and ad interaction data to show and measure ads.
- Air quality requests: When the App requests station data, search results, map bounds, or nearby station information from our backend API, request information such as station IDs, search keywords, coordinates, language headers, and basic network metadata may be processed.
How We Use Information
We use information to:
- Show air quality data and forecasts.
- Find nearby air quality stations.
- Display stations on a map.
- Save your language and favorite station preferences.
- Improve app reliability, performance, and user experience.
- Detect, diagnose, and fix crashes or technical issues.
- Display and measure advertisements.
- Respond to support requests when you contact us.
Location Information
Location access is used to identify air quality stations near you. You can deny or revoke location permission at any time through your device settings. If precise device location is unavailable, the App may use approximate IP-based geolocation as a fallback. The App may cache location information locally on your device to improve the nearby station experience.
Local Storage
The App stores some information on your device using secure local storage, including selected language, saved station IDs, cached station data, nearest station ID, and cached location data. This information helps the App remember your preferences and improve loading behavior. You can remove locally stored App data by clearing the App's data or uninstalling the App.
Third-Party Services
The App uses third-party services that may collect information according to their own privacy policies:
- Google Privacy Policy for Google Maps, Google AdMob, Firebase Analytics, and Firebase Crashlytics.
- Firebase Privacy and Security.
- Google AdMob privacy information.
- IP geolocation service legal information, where applicable for approximate location fallback.
Advertising
The App may display banner ads through Google AdMob. AdMob may use advertising identifiers and other data to provide, personalize, limit, and measure ads, depending on your device settings, consent choices, region, and applicable law. You can manage ad personalization through your Google account and device privacy settings.
Analytics and Crash Reporting
We use Firebase Analytics to understand general app usage and Firebase Crashlytics to receive crash and diagnostic reports. This information helps us identify problems, improve stability, and make the App better. Crash reports may include technical details such as device model, operating system version, app version, timestamps, stack traces, and diagnostic metadata.
Data Sharing
We do not sell your personal information. We may share information with service providers that help operate the App, including Google services, Firebase, AdMob, mapping services, IP-based geolocation providers, and our backend API providers. We may also disclose information if required by law, regulation, legal process, or to protect our rights, users, or the public.
Data Retention
Locally stored App data remains on your device until you clear App data, remove the information through App features where available, or uninstall the App. Data processed by third-party services is retained according to those providers' policies and settings. Backend API logs and diagnostics, if any, are retained only as long as reasonably necessary for app operation, security, analytics, troubleshooting, and legal compliance.
Your Choices
- You can grant, deny, or revoke location permission in your device settings.
- You can clear locally stored App data through your device settings or by uninstalling the App.
- You can manage advertising personalization and identifiers in your device or Google account settings.
- You can contact us to ask privacy-related questions or request assistance.
Children's Privacy
The App is not intended for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the App, please contact us so we can take appropriate action.
International Transfers
The App and its third-party services may process information on servers located in countries other than your country of residence. These countries may have data protection laws that differ from those in your location.
Security
We use reasonable technical and organizational measures to protect information processed by the App. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
Changes to This Policy
We may update this Privacy Policy from time to time. When we make changes, we will update the "Last updated" date above. Your continued use of the App after changes are posted means you accept the updated policy.
