How It Works

Data Collection

Visit phone specification pages on GSMArena and the extension will automatically extract and cache phone data including:

• Brand and model
• Dimensions, weight, and build materials
• Display specifications
• Operating system and chipset
• Memory and storage
• Camera specifications
• Battery capacity and charging
• Colors and pricing

Data Storage

All data is stored locally in your browser. Nothing is sent to external servers.

Data Export

The extension provides functionality to export your cached data as CSV (accessible via browser's extension storage API).

2. Click "Load Temporary Add-on"
3. Select cachearena/manifest.json
