Privacy policy

Last updated: October 18, 2026

This privacy policy explains what happens to your data when you use LeaseMathHub ("we", "the site"), in any of its language versions.

Numbers you type into the calculators

All calculations run locally in your web browser. The numbers you enter are not sent to our server and are not stored by us. Your currency and light/dark theme choices may be saved in your own browser's local storage so the site remembers them; you can clear them at any time.

Fonts

Fonts are served from our own server. We do not load fonts or scripts from third-party font services.

Server logs

Like most websites, our hosting provider may keep standard technical logs (IP address, browser type, pages requested, date and time) for security and to keep the site running.

Advertising and cookies

This site may show ads served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

You may opt out of personalised advertising by visiting Google Ads Settings. You can also learn more at How Google uses information from sites that use its services.

Visitors from the UK, the European Economic Area and Switzerland will be asked for consent before personalised ads or non-essential cookies are used.

Your rights

Depending on where you live (for example under the GDPR/UK GDPR or US state privacy laws such as the CCPA), you may have the right to access, delete or object to the processing of your personal data. Contact us to exercise these rights.

Children

The site is not directed at children under 13 and we do not knowingly collect their data.
