Privacy Policy

Your Data Stays in Your Browser

All portfolio data you enter (cash amounts, holdings, share counts, debts, valuables) is stored exclusively in your browser's localStorage. It is never transmitted to or stored on our servers beyond what is needed for a single calculation request.

What the API Receives

When you calculate your zakat, the following data is sent to our server-side API for processing:

• Ticker symbols (e.g., AAPL, VTI)
• Share counts and prices per share
• Cash and debt amounts (aggregate numbers only)
• Calculation preferences (nisab method, jewelry treatment)

This data is used only to compute your zakat obligation and is not stored, logged, or associated with any identity. API requests are processed and discarded.

No Accounts or Personal Information

We do not require account creation, email addresses, names, or any personally identifiable information. There is no login, no profile, and no way for us to identify individual users.

No Tracking or Analytics

We do not use cookies, tracking pixels, or third-party analytics services. We do not track which pages you visit, how long you spend, or what you enter into the calculator. We use Sentry for error monitoring only — it captures technical diagnostics when something breaks, not your activity or financial data.

Discovery Cache

When you enter a ticker symbol that isn't in our pre-computed database, our system automatically looks it up from SEC filings or Yahoo Finance. The resulting financial ratio (not your personal data) is cached so that future users benefit from faster lookups. This cache contains only ticker-level financial data (e.g., “AAPL has a zakatable ratio of 12.3%”) and is not linked to any individual user.

Third-Party Services

• Vercel — Hosts our application and serverless functions
• Yahoo Finance — Provides stock prices (queried server-side, not from your browser)
• SEC EDGAR — Provides regulatory filing data for ratio calculations
• Sentry — Error monitoring service. Receives technical diagnostics (error messages, page URLs, performance metrics) when something goes wrong. Does not receive your portfolio data, holdings, or financial amounts.

None of these services receive your personal information or portfolio composition. They only receive individual ticker symbol lookups (Yahoo Finance, SEC EDGAR) or technical error reports (Sentry).

Clearing Your Data

To delete all data stored in your browser, clear your browser's localStorage for this site, or use your browser's “Clear site data” feature. This will remove all saved portfolio information.
