🏗️ Architecture

StorageFlow follows a modular architecture with clear separation of concerns:

Component Structure

StorageFlow/
├── manifest.json          # Extension configuration
├── src/
│   ├── background/         # Service worker & background tasks
│   ├── content/           # Content script for page interaction
│   ├── popup/             # Main UI components
│   └── assets/            # Icons and static resources
└── docs/                  # Documentation (auto-generated)

Technology Stack

• Manifest V3: Latest Chrome extension standard
• Vanilla JavaScript: No external dependencies for performance
• Modular CSS: Structured stylesheets with theme support
• Chrome APIs: Extensive use of storage, tabs, scripting, and contextMenus APIs

🛡️ Security & Privacy

StorageFlow is built with security and privacy as top priorities:

• No External Connections: All operations are performed locally
• Minimal Permissions: Only requests necessary permissions
• Data Isolation: Respects Chrome's security model
• No Data Collection: Zero tracking or analytics
• Open Source: Full transparency of all operations
