Privacy Policy

Last updated: 23 January 2026

Overview

MortgageViz is designed with privacy at its core. We believe your financial data is yours alone. This policy explains how we handle information when you use our mortgage calculators and tools.

Data We Collect

Calculator Inputs

When you use our calculators, any mortgage details you enter (loan amount, interest rate, term, overpayment amounts) are processed entirely in your browser. This data is never sent to our servers.

Analytics

We use Plausible Analytics, a privacy-focused analytics service that does not use cookies and does not collect personal data. We only see aggregate statistics like page views and general geographic regions. No individual user tracking occurs.

Account Data (Optional)

If you choose to create an account, we store your email address to enable login and to save your mortgage data for tracking over time. You can delete your account and all associated data at any time.

How We Use Data

  • To provide and improve our calculators and tools
  • To save your mortgage data if you have an account
  • To understand how our site is used (aggregate analytics only)
  • To respond to support requests

Data Sharing

We do not sell, rent, or share your personal data with third parties for marketing purposes. We may share data only:

  • With service providers who help us operate the site (hosting, email)
  • If required by law or to protect our legal rights

Cookies

We use minimal cookies. If you create an account, we use a session cookie to keep you logged in. We do not use advertising or tracking cookies.

Your Rights

Under UK GDPR, you have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your data
  • Object to or restrict processing
  • Data portability
