Chart Funda — Privacy Policy

Last updated: 5 Oct 2026

Chart Funda is a Chrome extension that displays Indian stock market data (fundamentals, ownership, peer comparisons, and corporate filings) alongside TradingView charts.

What we collect

Nothing. Chart Funda does not collect, store, or transmit any personal information, browsing history, financial data, or usage analytics to any server we control. We have no backend, no database, and no account system.

What's stored locally

The extension uses Chrome's local storage (chrome.storage.local), which never leaves your browser, to remember:

- Your theme preference (light/dark)

- Your pill display mode (classic/compact)

- Your consolidated/standalone results preference

- Whether the Chartink redirect is enabled

- Whether the TradingView fundamentals panel is enabled

- Whether click-anywhere-to-minimize is enabled

- A temporary cache of company, peer, filings, and rank data (short-lived)

Third-party requests

To show fundamentals data, Chart Funda fetches publicly available pages from:

- Screener.in (company financials, shareholding, peer data)

- Trendlyne.com (company earnings dates)

- api.kite.trade (public BSE instrument list — no account or API key required)

- google.com/s2/favicons (site icons shown next to dashboard links — image requests only, no data sent)

- fish-rs-board.pages.dev (curated NSE corporate filings list and the experimental Fish RS rank shown in the Filings tab — NSE PDF links open in a new tab on request, no filing content is fetched)

These requests are made directly from your browser to display data in the extension. We do not see, log, or store the contents of these requests ourselves.

Permissions

- Storage: to save your preferences and cache locally, as above.

- Tabs: used only by the optional Chartink redirect, to read a Chartink stock page's address and open the equivalent TradingView chart.

- Website access (Screener.in, Trendlyne.com, api.kite.trade, TradingView): to read the public company data listed above and show the panel on TradingView charts. fish-rs-board.pages.dev is also contacted but is CORS-open, so it needs no extension permission.

Changes

Any changes to this policy will be reflected on this page with an updated date above.
