Privacy Policy

Your data stays yours. Nexus Helper is designed with privacy-first principles — most data never leaves your device.

Last updated: February 2026 | Version 3.3.0

Information We Collect

Nexus Helper is designed with privacy in mind. Here's what we collect:

Locally Stored (on your device only):

  • Clipboard history (last 10 items)
  • Recent routes and pinned routes
  • Project mappings and file indexes
  • Widget position and preferences
  • Editor preferences
  • Firebase authentication tokens (if you sign in)

    • Transient Data (never stored):

  • Page content and DOM structure for context generation
  • Console errors and network requests
  • Screenshots (only when explicitly requested)
  • Selected text on the page

    • Authentication Data (Firebase):

  • Email address (if you create an account)
  • Google account info (if you use Google Sign-in)
  • User ID and display name

    • How We Use Your Information

    Local Data Usage:

  • Clipboard history: To show you recently copied items
  • Recent routes: To provide quick navigation between pages
  • Project mappings: To resolve routes to source files
  • Widget preferences: To remember your settings

    • API Docs Integration (Optional):

  • If you sign in, we fetch your published API documentation from NexusDocer
  • This data is only used to display your API docs in the widget
  • You can attach API docs to your AI context

    • We do NOT:

  • Track your browsing history
  • Collect data about the websites you visit
  • Share your data with third parties
  • Use your data for advertising
  • Sell your personal information

    • Data Storage & Security

    Local Storage:

  • All local data is stored using Chrome's storage APIs
  • Data never leaves your browser unless you explicitly use cloud features
  • Context generation happens entirely on your device

    • Firebase Authentication:

  • Authentication uses Firebase's secure infrastructure
  • Tokens are stored securely in Chrome's local storage
  • Tokens are automatically refreshed and expire after 1 hour

    • API Docs (Optional Cloud Feature):

  • API documentation is fetched from NexusDocer's Firebase backend
  • Only authenticated users can access their own API docs
  • API doc content is cached locally for performance

    • Your Rights & Data Control

    You have full control over your data:

  • **Export/Import:** You can export all your settings and data at any time
  • **Clear Data:** You can clear clipboard history, recent routes, and all stored data
  • **Sign Out:** You can sign out of Firebase authentication at any time
  • **Uninstall:** Uninstalling the extension removes all local data

    • To delete your account and all associated data:

  • Sign in to the widget
  • Go to Settings > Account
  • Click "Delete Account"
  • This removes your Firebase auth data and all API doc associations

    • Note: Deleting your account does not delete published API docs on NexusDocer. Manage those separately on the NexusDocer platform.
