Privacy Policy

1. Introduction

Welcome to DeRadar. We are committed to protecting your privacy and ensuring transparency in how we handle data. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you use our decentralized aircraft tracking service.

DeRadar is built on decentralized technologies (Ar.io & Arweave), which fundamentally changes how data is stored and managed compared to traditional centralized services.

2. Information We Collect

2.1 Aircraft Tracking Data

DeRadar displays publicly available aircraft tracking information, including:

• Aircraft identification codes (ICAO addresses, flight numbers)
• Position data (latitude, longitude, altitude)
• Flight parameters (speed, heading, vertical rate)
• Aircraft type and registration information
• Origin and destination airports

This data is publicly broadcast by aircraft via ADS-B (Automatic Dependent Surveillance-Broadcast) and is collected by community-operated receivers worldwide.

2.2 Usage Information

We may collect anonymous usage statistics through our analytics provider, including:

• Page views and navigation patterns
• Browser type and version
• Device information and screen resolution
• Approximate geographic location (country/region level)
• Referral sources

2.3 Local Storage

The DeRadar application uses browser local storage to save your preferences, including:

• Map view settings (position, zoom level)
• Display preferences and filters
• Theme settings (dark/light mode)
• Mini app settings and configurations

This data is stored locally on your device and is not transmitted to our servers.

3. How We Use Information

We use collected information for the following purposes:

• Providing real-time and historical aircraft tracking services
• Improving the functionality and performance of DeRadar
• Understanding usage patterns to enhance user experience
• Maintaining and troubleshooting technical issues
• Complying with legal obligations and regulations

4. Decentralized Data Storage

DeRadar leverages the Arweave network for permanent, decentralized data storage:

• Historical aircraft tracking data is stored on the Arweave blockchain, which is a permanent, immutable, and decentralized storage network
• Once data is stored on Arweave, it cannot be deleted or modified - this is a fundamental characteristic of blockchain technology
• Data stored on Arweave is publicly accessible and replicated across multiple nodes in the network
• We use Ar.io gateways to access and retrieve data from the Arweave network

5. Data Sharing and Disclosure

DeRadar does not sell your personal information. We may share data in the following circumstances:

• Public Data: Aircraft tracking data displayed on DeRadar is already publicly available and may be accessed by anyone
• Service Providers: We may share data with trusted third-party service providers who assist in operating our service (e.g., analytics, hosting)
• Legal Requirements: We may disclose information if required by law or to protect the rights and safety of DeRadar, our users, or others
• Decentralized Network: Data stored on Arweave is automatically replicated across the decentralized network and is publicly accessible

6. Cookies and Tracking Technologies

DeRadar uses minimal cookies and similar technologies:

• Analytics Cookies: We use analytics tools to understand how visitors use DeRadar
• Functional Storage: Browser local storage is used to remember your preferences

You can control cookies through your browser settings. However, disabling cookies may limit certain functionality of DeRadar.

7. Data Security

We implement reasonable security measures to protect information:

• HTTPS encryption for all data transmission
• Secure hosting infrastructure
• Regular security assessments and updates
• The decentralized nature of Arweave provides additional security through distributed storage and cryptographic verification

However, no method of transmission or storage is 100% secure. We cannot guarantee absolute security of data.

8. Your Rights and Choices

You have the following rights regarding your data:

• Access: Request information about data we hold
• Local Data: Clear your local storage through browser settings
• Opt-out: Disable analytics through browser extensions or settings

Important Note: Due to the immutable nature of blockchain technology, data stored on the Arweave network cannot be deleted or modified once stored. This is a fundamental characteristic of decentralized permanent storage.

9. Children's Privacy

DeRadar does not knowingly collect information from children under 13 years of age. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.

10. International Data Transfers

DeRadar operates globally and data may be processed in various countries:

• The Arweave network is distributed across nodes worldwide, meaning data may be stored and accessed from multiple jurisdictions
• We ensure appropriate safeguards are in place when transferring data internationally

11. Third-Party Services

DeRadar integrates with third-party services and links:

• Arweave blockchain network
• Ar.io gateway services
• Analytics providers
• External mini apps (SkyQuery etc.)

These third parties have their own privacy policies. We are not responsible for their privacy practices.

12. Changes to This Privacy Policy

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