Data Collection
The Extension does NOT collect, transmit, or share any personal data.
What Data is Stored Locally
The Extension stores the following information locally on your device only:
- Visited Chart Links: When you click on a TradingView chart link, the URL is stored in your browser's localStorage to mark it as visited (displayed in purple color).
This data:
- Remains only on your device
- Is never transmitted to any server
- Is never shared with any third party
- Is never accessible to the extension developer
- Can be cleared by clearing your browser's localStorage or uninstalling the extension
What Data is NOT Collected

- Collect personal information (name, email, phone, address, etc.)
- Track your browsing history
- Access your financial information
- Monitor your trading activity
- Use cookies or tracking technologies
- Send any data to external servers
- Share data with third parties
- Use analytics or telemetry
How the Extension Works
The Extension operates entirely within your browser:
- Detects stock screener tables on www.screener.in/screens/* pages
- Reads company symbols from table links (e.g., "NATIONALUM" from "/company/NATIONALUM/")
- Adds a new column with TradingView chart links
- Stores clicked links in localStorage to mark them as visited

Third-Party Services
When you click a TradingView link, you will be redirected to TradingView's website (in.tradingview.com). At that point, TradingView's privacy policy applies. The Extension does not control or have access to any data collected by TradingView.
