How the Extension Works

ChartView Pro operates locally in your browser and only:

1. Accesses Screener.in Pages: The extension only activates on https://www.screener.in/company/* pages to provide chart visualization features
2. Local Data Storage: Uses Chrome's local storage API to save your chart display preferences (show/hide charts setting) locally in your browser
3. Chart Rendering: Processes publicly available financial data from Screener.in pages to create interactive charts
4. External Links: Provides links to TradingView.com for additional chart analysis

The extension requests the following permissions:

• activeTab: To access the current Screener.in tab and inject chart functionality
• scripting: To execute scripts that enhance the page with chart features
• Host Permission (https://www.screener.in/company/*): To operate only on relevant Screener.in company pages

These permissions are used solely to provide the extension's core functionality and are not used for data collection.
