Privacy Policy

1. Introduction

Nuclear Fallout Calculator ("we", "our", "the app") is an interactive web-based tool that simulates nuclear blast zones and fallout risk for educational and informational purposes only. This Privacy Policy explains how we collect, use, and protect information when you use our service.

2. Information We Collect

We may collect the following types of information:

  • Location data you provide: Addresses, zip codes, post codes, or town names entered into the calculator for blast-radius and fallout-risk calculations.
  • Map interaction data: Coordinates of bomb placement and observer pins you place on the map.
  • Device and browser information: IP address, browser type, operating system, screen resolution, and referring URL.
  • Usage data: Pages visited, features used, warhead selections, calculation results, and session duration.

Important: Location data you enter (addresses, coordinates) is used temporarily in your browser to perform the calculation. It is not stored persistently on our servers unless you explicitly choose to save or share your results.

3. How We Use Your Information

  • To provide nuclear fallout risk calculations based on the locations you enter.
  • To display interactive blast-zone maps and survival assessments.
  • To improve app performance, fix bugs, and enhance features through aggregated analytics.
  • To serve relevant advertisements via third-party ad networks.

4. Cookies and Tracking Technologies

We and our third-party partners use cookies and similar technologies, including:

  • Essential cookies: Required for the app to function (e.g., session management).
  • Analytics cookies: Google Analytics 4 (Measurement ID: G-GQNYEKM8N3) tracks aggregated, non-personal usage patterns — such as pages visited, warhead selections, risk-level outcomes, and calculation frequency — to help us improve the tool. No personally identifiable information (e.g., names, exact addresses) is sent to Google Analytics.
  • Advertising cookies: Google AdSense and its partners may place cookies to serve ads based on your interests and prior visits to this and other websites.

You can manage cookie preferences through your browser settings. Disabling certain cookies may affect app functionality.

5. Third-Party Services

We use the following third-party services:

  • Google AdSense: For displaying advertisements. Google may use cookies to personalise ads. See Google's ad policies.
  • Google Analytics: For aggregated usage analytics. See Google's privacy policy.
  • OpenStreetMap / Nominatim: For geocoding addresses and rendering map tiles. Queries are sent to OpenStreetMap's public API.

6. Data Sharing and Disclosure

We do not sell your personal information. We may share aggregated, non-identifiable data with analytics and advertising partners. We may disclose information if required by law or to protect the rights and safety of our users.

7. Your Rights

  • Access and deletion: You may request access to or deletion of any personal data we hold by contacting us.
  • Opt-out of personalised ads: Visit Google Ads Settings to manage ad personalisation preferences.
  • Do Not Track: We honour Do Not Track browser signals where technically feasible.

8. Children's Privacy

This app is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the app after changes constitutes acceptance of the revised policy.
