KashVector (kashvector.com) is a collection of free financial tools built for everyday people. This policy explains what data these tools handle — and what they deliberately do not.
No accounts, no personal data
KashVector has no sign-up, no login, and no user accounts. We do not collect, store, or transmit your name, email address, phone number, location, or any other personally identifiable information.
Tools that run entirely in your browser
The following tools perform all calculations locally in your browser. They make no network requests for calculation — none of the values you enter leave your device:
- Budget Planner
- Debt Recycling / Investment Property Calculator
- Portfolio Health Check
- FIRE Calculator
- Mortgage Calculator
- Salary Sacrifice / Super Compare
- Life Buyback Calculator
- Rent vs Buy vs Rent-vest Calculator
- 2026–27 Budget Impact Calculator
Values you enter into these tools stay in your browser. Some of them save your most recent inputs to your browser's local storage so they can be restored on your next visit (see "Local storage" below); this data never leaves your device.
Stock Evaluator, DCF Valuation and the Most Undervalued screens — network requests
Four tools — the Stock Evaluator, the DCF Valuation calculator, and the Most Undervalued ASX 300 and Most Undervalued S&P 500 screens — fetch live financial data from Yahoo Finance. When you enter a ticker symbol and run an analysis (or, for the undervalued screens, simply open the page), the tool sends one or more ticker symbols to a Cloudflare Worker endpoint operated by KashVector. The Worker forwards the request to Yahoo Finance and returns the financial metrics or live prices to your browser. The only data sent over the network is:
- The ticker symbol you entered (e.g.
AAPL,BHP.AX) - Your IP address, as seen by Cloudflare — used solely for rate limiting to prevent abuse
The Worker does not log ticker lookups against your IP address beyond a short-lived in-memory rate-limit window (approximately one minute). No lookup history is persisted server-side.
Local storage
KashVector tools use your browser's localStorage to save data on your own device so it can be restored on your next visit. Specifically:
- Theme preference (light or dark) — shared across all tools.
- Recent ticker symbols — the Stock Evaluator and DCF Valuation remember the last few symbols you searched, for quick-tap suggestions.
- Your entered values — most calculators (Budget Planner, Debt Recycling, Portfolio Health, FIRE, Mortgage, Salary Sacrifice, Life Buyback, Rent vs Buy, Budget Impact) save the inputs you last used so you don't have to re-enter them.
All of this data stays on your device. It is never shared, transmitted, or synced to any server. You can clear it at any time by clearing your browser's site data for kashvector.com.
Third-party services
- Yahoo Finance — provides stock data for the Stock Evaluator via our proxy. Yahoo's own privacy policy governs their handling of the proxied request: https://legal.yahoo.com/us/en/yahoo/privacy/index.html.
- Cloudflare — hosts the proxy Worker and serves this website via Cloudflare Pages. Cloudflare's privacy policy applies to network-level data they observe: https://www.cloudflare.com/privacypolicy/.
Analytics, advertising, and tracking
KashVector contains no analytics SDKs, no advertising SDKs, no crash reporters, and no fingerprinting scripts. Some pages contain an affiliate link to Sharesight (see below) — clicking that link may set a tracking cookie on the Sharesight domain, governed by Sharesight's own privacy policy.
Cookies
KashVector does not set any cookies directly. Cloudflare may set technical cookies as part of its infrastructure (e.g. for DDoS protection); these are governed by Cloudflare's policy above. If you click the Sharesight affiliate link on this site, Sharesight may set a cookie on their domain to track the referral — this is standard affiliate tracking and is governed by Sharesight's privacy policy.
Affiliate links
Some KashVector pages contain an affiliate link to Sharesight, a portfolio tracking service. If you purchase a paid Sharesight plan after clicking this link, KashVector may receive a commission. This comes at no extra cost to you — the special offer (save 4 months on an annual plan) is available exclusively through this link. KashVector does not receive any personal information about you from Sharesight, and the affiliate relationship does not influence the content or advice provided by any KashVector tool.
Children's privacy
KashVector is not directed at children under 13 and does not knowingly collect any information from them. Since these tools collect no personal information at all, this is structurally the case.
Not financial advice
All KashVector tools are provided for informational and educational purposes only. Nothing on this site constitutes financial, investment, tax, or legal advice. Consult a licensed professional before making any financial 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.
