Privacy Policy
HantaWorld provides hantavirus outbreak intelligence, country risk information, public health reports, and related educational content through the HantaWorld website and Android application.
1. Information We Collect
We do not require users to create an account to access the public website or Android app. The app may collect technical information needed to operate core features, including device platform, app version, locale, Expo push notification token, notification delivery status, and basic usage events from analytics or advertising services.
2. Push Notifications
If you allow notifications, the Android app sends an Expo push token to the HantaWorld API so we can deliver public health updates and newly published reports. You can disable notifications at any time from your device settings. Push tokens are used only for app notifications and are not sold.
3. Advertising and Cookies
The website may use Google AdSense Auto Ads, and the Android app may display ads through Google AdMob. Google and its partners may use cookies, advertising identifiers, device information, approximate location, diagnostics, and interaction data to deliver, measure, and personalize ads according to Google policies. You can manage browser cookies through your browser settings and mobile advertising preferences through Android privacy settings.
4. Analytics
The website uses Google Analytics to understand aggregate traffic and improve the service. Analytics data may include browser, device, page view, and approximate location information. We do not use analytics to identify individual medical status.
5. Public Health Content
HantaWorld publishes verified and source-attributed public health information. The service is for informational purposes only and does not provide medical diagnosis, treatment, emergency response, or patient-specific health advice.
6. How We Use Information
We use collected technical data to operate the app, deliver notifications, improve reliability, measure aggregate usage, prevent abuse, and support advertising. We do not sell personal information.
7. Data Sharing
We may share limited technical data with service providers that help operate the platform, including hosting providers, notification services, analytics providers, and advertising SDK providers. These providers process data according to their own terms and applicable law.
8. Data Retention and Security
We retain technical records only as long as needed for operational, security, analytics, or compliance purposes. We use encrypted connections and reasonable administrative and technical safeguards to protect platform data.
9. Your Choices
You can disable push notifications from Android settings, reset or limit your advertising ID from Android privacy settings, and use browser controls to manage cookies or analytics preferences.
