Stock Evaluator ("the app") is a free tool that includes two investing tools: the Buffett Evaluator, which scores publicly listed stocks against the investment criteria of Warren Buffett, Ray Dalio, and Benjamin Graham (with additional ROCE and Governance scoring for Indian NSE/BSE stocks); and the DCF Valuation tool, which estimates intrinsic value and margin of safety using Discounted Cash Flow and Dividend Discount models. This policy describes what data the app handles and what it does not.
No accounts, no personal data
The app has no sign-up, no login, and no user accounts. We do not collect, store, or transmit your name, email address, phone number, location, contacts, photos, device identifiers, or any other personally identifiable information.
What the app sends over the network
The app communicates with a Cloudflare Worker endpoint operated by the developer in the following situations:
- Company name search (autocomplete): As you type in the search box (after 3 characters), the text you have typed so far is sent to the Worker, which forwards it to Yahoo Finance's search API and returns a list of matching companies. This applies to both the Buffett Evaluator and DCF Valuation tools.
- Stock analysis (Buffett Evaluator): When you tap Analyse, the ticker symbol is sent to the Worker, which forwards it to Yahoo Finance's
quoteSummaryAPI and returns the company's financial metrics. - Stock valuation (DCF Valuation): When you tap Analyse, the ticker symbol and a request for live risk-free rate data are sent to the Worker, which forwards them to Yahoo Finance and returns the financial data needed to calculate intrinsic value.
In all cases the only additional data sent is your IP address, as seen by Cloudflare — used solely for rate limiting to prevent abuse. The Worker does not log search queries or ticker lookups against your IP address beyond the short-lived in-memory rate-limit window (one minute). No lookup history is persisted server-side.
Most Undervalued stock rankings
The app includes links to monthly "Most Undervalued" rankings for ASX 300, S&P 500, and NIFTY 500 stocks. Tapping these links opens kashvector.com in your device's default browser — outside the app. Once you leave the app, the privacy practices of that external site apply. No data is transmitted to that site from within the app itself.
Third-party services
- Yahoo Finance — provides the underlying stock data. Your ticker lookups are fulfilled by Yahoo's public API via our proxy. Yahoo's own privacy policy applies to their handling of the proxied requests: https://legal.yahoo.com/us/en/yahoo/privacy/index.html.
- Cloudflare — hosts the proxy Worker. Cloudflare's privacy policy applies to any network-level data they observe: https://www.cloudflare.com/privacypolicy/.
What the app stores on your device
The app uses your device's local browser storage (localStorage) to store the following:
- Recent tickers: The last few ticker symbols you searched in either tool, so they can appear as quick-tap chips on your next visit.
- Theme preference: Whether you have selected light or dark mode, so the app opens in your preferred theme.
None of this data ever leaves your device. It is not synced, shared, or transmitted to anyone. You can clear it at any time by uninstalling the app or clearing the app's data from Android Settings → Apps → Stock Evaluator → Storage → Clear data.
Analytics, advertising, and tracking
None. The app contains no analytics SDKs, no advertising SDKs, no crash reporters, no fingerprinting, and no third-party tracking of any kind.
Children's privacy
The app is not directed at children under 13 and does not knowingly collect any information from them. Since the app collects no personal information at all, this is structurally the case.
Permissions
The app requests only the standard Internet permission required to fetch stock data. It does not request access to your camera, microphone, location, contacts, storage, calendar, or any other sensitive device capability.
Data retention and deletion
No personal data is retained on our servers because none is collected. Any IP-based rate-limit counters held by the Cloudflare Worker expire within 60 seconds. To remove locally stored data (recent tickers and theme preference), uninstall the app or clear app data from Android Settings → Apps → Stock Evaluator → Storage → Clear data.
Not financial advice
The app's scores and valuations are informational and educational only. They are not financial advice, investment recommendations, or solicitations to buy or sell any security. You should conduct your own research and consult a qualified financial adviser before making investment decisions.
Changes to this policy
If this policy changes, the updated version will be published at the same URL with a new "Last updated" date. Material changes will also be noted in the app's release notes on Google Play.
