MortgageCalc UK ("we", "us", "our") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights. We operate at https://mortgage-overpay-calc.netlify.app.
The short version: we don't collect or store any of your mortgage data. All calculations happen entirely in your browser.
Calculator data: The mortgage figures you enter (balance, rate, term, overpayment amount) are processed entirely in your browser. We never transmit, store, or have access to this information.
Analytics: We may use anonymised analytics (such as page view counts) to understand how many people visit our site. This does not identify you personally.
Contact form: If you contact us via our contact page, we will receive your name and email address solely to respond to your message. We do not share this with third parties.
Our site may use minimal functional cookies required for the site to operate. We do not use advertising cookies or tracking cookies that follow you across other websites. You can control cookies through your browser settings.
We use the following third-party services:
We do not sell, rent, or share your data with advertisers or marketing companies.
Under UK GDPR, you have the right to access, correct, or request deletion of any personal data we hold. Since we hold virtually no personal data, this is rarely applicable — but if you have a query, please contact us via the contact page.
We may update this policy occasionally. The "last updated" date at the top of this page will reflect any changes. Continued use of the site after changes constitutes acceptance of the updated policy.
If you have any questions about this privacy policy, please use our contact page.
