Welcome to Nexus Radar. Your privacy and data security are our highest priorities. This Privacy Policy explains how our Chrome Extension collects, uses, and protects your information, particularly regarding our free daily tier, paid subscriptions, and commercial licensing model.
To comply with the Google Chrome Web Store Developer Program Policies and international data protection laws, this document outlines our transparent data practices.
Nexus Radar is built on a strict "Zero-Knowledge" architecture. We do not operate central database servers to harvest user profiles, we do not require user account registration to use the extension, and we do not track your browsing activity across the web. All core P2P connection analysis happens directly inside your own browser's local sandbox.
To provide real-time connection intelligence during peer-to-peer (P2P) video chats, the extension processes the following technical metadata:
Peer IP Addresses: The extension extracts the IP address of the stranger you connect with via standard WebRTC and WebSocket signaling.
Geographic Metadata: The extension queries public geolocation APIs (such as ipwho.is, ipapi.co, get.geojs.io, ip-api.com) using the peer's IP address to retrieve geographic context (City, Country, Region, ISP).
Device & Browser Signals: The extension analyzes Session Description Protocol (SDP) fingerprints to estimate the peer's device category (e.g., Mobile vs. Desktop).
We DO NOT collect or access:
Your personal identifiable information (Name, Physical Address, SSN).
Your personal IP address or browsing history outside of supported video chat platforms.
Audio, video, or text chat content streams.
The data processed by Nexus Radar is used for one single purpose:
To display real-time connection intelligence, geolocation, and VPN detection on your screen during active P2P video chat sessions.
We use this data to populate the floating UI panel and popup dashboard within the extension so you can safely identify the network origin and potential risk signals of the person you are communicating with.
Nexus Radar operates under a freemium model with paid tier upgrades (Monthly, 6-Month, 1-Year, and Lifetime licenses).
All payment processing, orders, subscriptions, invoicing, tax calculation (VAT/GST/Sales Tax), and financial transactions are handled exclusively by Lemon Squeezy (lemonsqueezy.com), our authorized Merchant of Record (MoR).
When you click "Buy" or "Upgrade", you are securely redirected to Lemon Squeezy's hosted checkout domain (fastrsoft.lemonsqueezy.com).
No Financial Data Handling: The Nexus Radar Chrome Extension and its developers never see, collect, process, or store credit card details, CVC codes, bank accounts, or billing addresses.
Upon purchasing a paid subscription or lifetime license, Lemon Squeezy issues a unique License Key.
When you enter your key into the extension settings, the background service worker makes secure POST requests to Lemon Squeezy's official Licensing API (https://api.lemonsqueezy.com/v1/licenses/activate and /v1/licenses/validate).
This validation check returns only the license status (active, expired, unpaid), variant plan name, and an anonymized instance ID.
The extension checks key validity every 24 hours. If a subscription is cancelled or refunded, Lemon Squeezy returns an inactive status, and the extension automatically reverts back to the Free tier.
Offline Grace Period: Includes a 3-day grace period so valid users maintain premium access during momentary internet disruptions.
Free Tier: Includes 20 IP lookups per day and a 100-entry local history log.
Premium / Ultimate Tier: Unlocks unlimited daily lookups, unlimited history logs, CSV export/import capabilities, and advanced ISP/VPN risk analysis.
Local Storage Only: Encounter logs (Peer IP, Location, Timestamp) are saved locally on your device using Chrome's secure chrome.storage.local API. The extension utilizes the unlimitedStorage permission solely to prevent your historical logs from being deleted by browser storage caps.
No Cloud Databases: Your encounter logs and personal license status are never uploaded to any remote cloud database or tracking server.
User Deletion: You have full control to clear your local history (24 hours, 7 days, 30 days, or ALL data) at any time via the extension's Settings tab. Uninstalling the extension permanently wipes all stored data.
To be 100% transparent and fully compliant with the Google Chrome Web Store Developer Program Policies:
❌ We do NOT sell user data to third parties.
❌ We do NOT transfer user data to data brokers or advertising networks.
❌ We do NOT use or transfer user data for creditworthiness or lending purposes.
❌ We do NOT use remote code execution. All logic is self-contained within the compiled extension package.
If you need to cancel a subscription, update billing details, or request a refund according to Lemon Squeezy's terms:
You can manage your subscription anytime via the order confirmation email link provided by Lemon Squeezy.
