Privacy Policy

Last updated: January 2025

The Short Version

We don't collect your financial data. All calculator inputs stay in your browser. We use minimal analytics to understand site usage. That's it.

Information We Don't Collect

Let's start with what we don't do:

  • We don't collect or store your financial information (loan amounts, income, debts, etc.)
  • We don't require you to create an account
  • We don't sell any data to third parties
  • We don't use tracking cookies for advertising
  • We don't share data with financial institutions

Calculator Data

All calculations are performed locally in your web browser using JavaScript. The numbers you enter into our calculators never leave your device. When you close the browser tab or refresh the page, your data is gone—we never see it.
