DNAF-1 Privacy Policy

1. Information We Collect

1.1 Location Data

DNAF-1 collects and uses your device's location information for the following purposes:

• Real-time Position: Your current GPS coordinates to display your location on the map and calculate fallout exposure at your position
• Ground Zero Coordinates: Locations you manually select or input for fallout simulation purposes
• Map Interaction: Coordinates associated with map panning, zooming, and marker placement

How We Use It: Location data is processed locally on your device for fallout calculations and is NOT transmitted to our servers or any third parties.

1.2 Weather and Wind Data

The App retrieves real-time weather and wind data from third-party services:

• NOAA (National Oceanic and Atmospheric Administration): Wind speed, direction, and atmospheric conditions
• Location-based requests: Your location coordinates are sent to NOAA servers to retrieve relevant weather data

Third-Party Privacy: NOAA's data services are subject to their own privacy policies. We do not control NOAA's data practices.

1.3 Map Data

The App uses Google Maps Platform services:

• Google Maps API: Displays interactive maps and terrain features
• Google Elevation API: Retrieves elevation data for terrain calculations
• Google Places API: Location search and geocoding (DNAF-1 Pro only)
• Coordinates sent to Google: Map tile requests include your viewing area coordinates

Third-Party Privacy: Google's collection and use of map data is governed by Google's Privacy Policy.
