Terms of service

LEGAL AGREEMENT: These Terms of Service ("Terms") constitute a legally binding agreement between you and Noxdren, LLC ("Company," "we," "us," or "our") governing your use of the RangeSight application and related services.

1. ACCEPTANCE OF TERMS

By downloading, installing, accessing, or using RangeSight ("the App," "the Application," or "the Service"), you acknowledge that you have read, understood, and agree to be bound by these Terms of Service, our Privacy Policy, and our Disclaimer (collectively, the "Agreement").

IF YOU DO NOT AGREE TO ALL TERMS OF THIS AGREEMENT, DO NOT DOWNLOAD, INSTALL, OR USE THE APPLICATION. Your continued use of RangeSight after any modifications to these Terms constitutes acceptance of those changes.

We reserve the right to modify these Terms at any time. Material changes will be communicated through the App or website. It is your responsibility to review these Terms periodically for updates.

2. DESCRIPTION OF SERVICE

RangeSight is a drone flight planning application that uses two proprietary engines, RangeIQ™ (single-point range analysis) and RangeIQ+™ (multi-leg waypoint mission analysis), to provide:

• Point-to-Point range analysis powered by RangeIQ™ ("safe-return ring" estimates based on weather, battery, payload, and aircraft specifications)
• Waypoint Mission analysis powered by RangeIQ+™ (leg-by-leg feasibility checks for imported routes in Litchi, DJI WPML, GPX, and KML formats)
• Multi-Battery (hot-swap) planning with automatic swap-point identification for missions that exceed a single charge
• Weather data integration for flight planning
• Map visualization with range rings, flight boundaries, and color-coded mission segments
• Offline map capabilities for remote operations
• Multi-drone database with manufacturer specifications and a custom drone builder
• Battery, cycle, and payload calculation tools
• Fine-tune calibration that adapts predictions to your specific aircraft and conditions

The Service is designed to assist drone pilots in flight planning and is intended for INFORMATIONAL AND EDUCATIONAL PURPOSES ONLY. RangeSight is NOT a safety system, navigation device, or certified aviation tool.

6. INTELLECTUAL PROPERTY RIGHTS

All intellectual property rights in and to RangeSight, including but not limited to the RangeIQ+™ and RangeIQ™ algorithms, software code, user interface design, and trademarks ("RangeSight," "RangeIQ+," and "RangeIQ"), are and shall remain the exclusive property of Noxdren, LLC and its licensors. These Terms do not grant you any rights to our intellectual property except for the limited license expressly granted herein.

Third-party content, including drone specifications, map data, and weather information, remains the property of their respective owners and is used under license or fair use provisions.

7. THIRD-PARTY SERVICES AND CONTENT

RangeSight integrates with third-party services, including:

• Weather Services: Real-time weather data from OpenWeatherMap and other providers
• Mapping Services: Map tiles and satellite imagery from OpenStreetMap, Esri, CartoDB

• Google Firebase (Analytics & Crashlytics): Anonymized app-usage events (app opens, screen views, map generations, weather fetches, mission imports, upgrade modal opens, purchase initiations) and automatic crash reports (device model, OS version, stack trace) are sent to Google Firebase to improve reliability and inform product decisions. A randomly-generated, app-scoped Firebase Installation ID is associated with these events; it is not your Google account or advertising ID and resets when you reinstall. The contents of your missions, coordinates, and inputs are never sent. Disable any time at More → Settings → Anonymous analytics.
