My portfolio is worth ₹2 crore. It includes my life's savings, my retirement plan, and my children's education fund. I'm not giving that data to anyone.
The problem with most portfolio trackers
Moneycontrol stores your portfolio on their servers. MarketsMojo requires broker login credentials. Groww and Kuvera need bank account linking. INDMoney asks for your PAN and Aadhaar. Every convenience comes with a privacy trade-off.
Data breaches happen. In 2023, a major Indian financial platform leaked 30 lakh users' financial data. Portfolio values, stock holdings, transaction history — all exposed.
How White Stallion AI is different
White Stallion AI is a single HTML file that runs entirely in your browser. When you upload a CSV, the file is processed by JavaScript on your device. The parsed data is stored in your browser's localStorage — on your computer, not on any server.
No account creation required. No email, no phone number, no PAN. You can use the entire app without even signing in with Google (OAuth is optional, for convenience features only).
No server storage. The Vercel deployment serves the HTML file. That's it. There's no database, no user table, no portfolio storage on the backend.
No API keys for your broker. You download a CSV from your broker and upload it to the app. The app never connects to your broker account.
What about the AI?
When you use Ask Stallion, your portfolio context is sent to the AI model for that specific query. No data is stored after the response. Each conversation is ephemeral. If you use the free tier (Haiku), queries go through a Vercel proxy. If you use BYOK (your own API key), queries go directly to Anthropic. In both cases, no portfolio data is retained.
Privacy isn't a feature. It's the architecture.
