Privacy Policy — Kite Fundamentals Overlay
What the extension does
Kite Fundamentals Overlay is a free Chrome extension that shows stock fundamentals (P/E ratio, ROE, Debt/Equity, price, RVOL, 52-week range, earnings date) in a small overlay on Zerodha Kite (kite.zerodha.com and kite-demo.zerodha.com).
What it reads from your browser
Only one thing: the stock trading symbol currently visible on the Kite page (e.g. "RELIANCE", "TCS"). It reads this from the page's DOM by matching a pattern like an NSE code.
Nothing else on the page is read — no account information, holdings, balances, order history, or any other content.
What it sends to our server
When a new symbol is detected, the extension makes a GET request to kfo-api.cookiescursor.com/api/stock/<SYMBOL>/. The symbol comes from the URL path — no request body, no cookies, no user identifiers of any kind are sent.
What our server stores
The server caches publicly available fundamental data in a DailySnapshot table keyed on (symbol, date). The row contains only the stock symbol, the date, and the financial metrics returned by Yahoo Finance (via yfinance).
There is no user ID, IP address, session token, or any other per-user field stored anywhere — not in the database, not in logs. Two people looking up the same stock on the same day read from the exact same cached row. The cache resets daily (one snapshot per symbol per calendar day).
Third-party data source
Fundamentals are fetched from Yahoo Finance via the open-source yfinance library. We don't control the accuracy of that data. The extension displays a disclaimer for this reason.
What we don't do
- No accounts, sign-in, or profiles of any kind.
- No cookies set by the extension or the API.
- No analytics, tracking pixels, or third-party scripts.
- No data sold or shared with any third party.
Changes
If this policy changes, an updated version will be posted at this same URL with a new "Last updated" date.
