DudeMap Privacy Policy

Last updated: December 2025

Welcome to the Privacy Policy for DudeMap — a free online map viewer and web-based geospatial file visualizer. Here you can understand how your map files and data are handled securely.

1. GeoJSON, FGB & Geospatial Files You Upload

Your uploaded map files are:

• processed locally in your browser
• never uploaded to any server
• never logged, stored, or transmitted

Your map and geospatial data stays 100% on your device.

2. Cookies

We use minimal cookies only for:

• basic website functionality
• anonymous traffic analytics

3. Analytics

DudeMap uses privacy-friendly analytics (like Cloudflare Analytics) to understand:

• feature usage
• performance
• traffic patterns

No personal or location information is collected.

4. Map Rendering Technologies

We use open-source mapping libraries:

• MapLibre GL - interactive maps
• deck.gl - rendering GeoJSON & geospatial layers

These libraries do not store or transmit your files.

5. Data Security

Because everything runs in the browser, your map data, GeoJSON, and FGB files never leave your machine.
