Privacy Policy

Last updated: June 4, 2026

Short version: we don't collect your personal or financial information. Everything you type into our calculators stays in your browser.

The data you enter into calculators

Every calculation on Paysaurius runs entirely in your web browser using client-side JavaScript. The figures you enter — balances, rates, terms, cash amounts — are never transmitted to us or to any third party. We have no backend server that receives them, and no database that stores them. When you close the tab, the data is gone.

Information we do not collect

  • We do not require accounts, logins, or registration.
  • We do not collect names, email addresses, phone numbers, or financial details.
  • We do not sell, rent, or share personal information — because we don't have any.
  • We do not operate lead-generation forms that pass your details to lenders.

Cookies and analytics

Paysaurius does not set advertising or tracking cookies. If we enable analytics in the future, we will use a privacy-friendly, cookieless solution that measures aggregate page views without profiling individuals or tracking you across sites. This page will be updated before any such change takes effect.

Server logs

Like virtually all websites, our hosting provider may keep standard server logs (such as IP address, browser type, and pages requested) for security and reliability. These logs are not used to identify you and are retained only as long as needed for operational and security purposes.

Advertising (not currently active)

We do not currently display ads. If we introduce advertising in the future (for example, Google AdSense), the ad provider may use cookies or similar technologies subject to their own privacy policies. We will update this page and provide any legally required notices and choices before ads go live.

Third-party links

Our guides may link to external resources. We are not responsible for the privacy practices of other sites; external links open with rel="noopener noreferrer" for your security.

Children's privacy

Paysaurius is intended for adults making mortgage decisions and is not directed to children under 13.

Your rights

Because we don't collect personal information, there's nothing for us to access, correct, or delete on your behalf. If you have questions about this policy, email privacy@paysaurius.com.

Changes to this policy

We may update this policy as the site evolves. Material changes will be reflected by the "last updated" date above.
