Privacy Guarantee

Your financial data is yours. Here is exactly how Hisaab protects it.

Zero network requests with your data

Hisaab is a static website. After the initial page load, it makes zero outbound network requests with your trade data. Your CSV is parsed in your browser. Your P&L is computed in your browser. Your journal notes are stored in your browser. Nothing is sent to any server, ever.

How to verify: Open your browser DevTools (F12), go to the Network tab, upload your tradebook, and watch. You will see zero requests to any external server.

No server, no database

Hisaabis deployed as a static export on a CDN. There is no backend server, no database, no API, and no authentication system. Your data lives in your browser's IndexedDB storage and nowhere else.

No analytics tracking

No Google Analytics. No Mixpanel. No PostHog. No tracking pixels. No cookies. Hisaab does not collect any usage data, behavioral data, or personally identifiable information.

Open source -- verify it yourself

Every line of code is publicly available under the MIT license. You don't have to trust our claims -- you can read the source code and verify them yourself.

Your data, your control

  • ExportDownload all your data as JSON or CSV at any time from the dashboard.
  • DeleteClear all data with one click. No "are you sure you want to cancel?" dark patterns.
  • Self-hostClone the repo, run npm run build, and deploy the out/ folder anywhere.

Storage safety

Hisaab requests persistent storage from your browser to prevent accidental data eviction. We also prompt you to back up your data periodically. Since everything is browser-based, we recommend exporting a JSON backup regularly -- especially before clearing browser data or switching devices.

What Hisaab does send

For complete transparency: outbound links to trymetis.app (our parent product) include UTM parameters that tell Metis the click came from Hisaab. This tracks the click, not your identity or trading data. No trade data, no P&L numbers, no personal information is included in these links.
