Privacy Policy

TL;DR: We don't collect, store, or share any personal information. Your data stays on your device. This extension is completely offline and privacy-first.

Introduction

This Privacy Policy describes how "Lumina by HassTagg" extension collects, uses, and handles user data. This extension is committed to protecting user privacy and follows Google Chrome's privacy guidelines.

Data Collection

We do NOT collect, store, or transmit any personal information.

The extension operates entirely offline and uses only local browser storage (Chrome Storage API) to save your preferences and shortcuts.

Data Storage

All data is stored locally on your device using Chrome's secure storage system:

  • Website shortcuts and custom names
  • Background image uploads (stored locally)
  • UI preferences (grid size, time format, etc.)
  • Bookmark import selections (temporary during import)

Third-Party Services

The extension uses Google's favicon service (google.com/s2/favicons) to automatically fetch website icons. This is a standard, privacy-respecting service that only receives the URL to generate an icon.

Permissions Used

Storage Permission:
To save your shortcuts and preferences locally.

Host Permissions:
To fetch favicons from websites you add as shortcuts.

Data Sharing

No data is shared with anyone. Everything stays on your device. We have no servers, databases, or third-party analytics.

User Rights

You have complete control over your data:

  • Delete Data: Remove shortcuts and reset preferences anytime
  • Uninstall: All data is removed when you uninstall the extension
  • Export/Import: No external export needed - everything is local

Security

The extension follows security best practices:

  • Uses HTTPS for all external requests when possible
  • Content Security Policy prevents cross-site scripting
  • No inline JavaScript execution
  • Regular code audits and updates

Children's Privacy

This extension is not intended for children under 13. We do not collect any information that could identify children, but we recommend parental supervision for users under 18.

Changes to This Policy

Any changes to this privacy policy will be posted here and updated in the extension. We will never change our core privacy principles without clear user notification.
