Privacy Policy

Last updated: August 2026

This Privacy Policy explains how Kleinfeld Mortgage Calculators (“we”, “us”, “our”) collects, uses, stores and protects information when you visit or use this website (the “Site”). We are committed to protecting your privacy and handling any personal data we do collect openly, fairly and in line with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.

1. Who We Are

Kleinfeld Mortgage Calculators provides free, independent online calculators covering mortgages, property and personal finance for UK users. For any privacy-related query, you can reach us via our Contact page.

2. Information We Collect

We have deliberately built this Site so that you do not need to create an account, log in, or provide personal details to use any calculator. Specifically:

Calculator inputs — figures you enter into a calculator (e.g. income, property price, mortgage balance) are processed entirely in your web browser using JavaScript. They are not transmitted to, or stored on, our servers.
Contact form — if you email us via the details on our Contact page, we will process the name, email address and any information you choose to include, solely to respond to your query. We retain this correspondence only for as long as reasonably necessary to deal with the matter and any follow-up.
Automatically collected data — like most websites, our hosting and analytics providers may automatically log technical information such as your IP address, browser type, device type, pages visited, and time spent on the Site. This is used in aggregate to understand how the Site is used and to keep it secure; it is not used to identify you personally.
Currency Converter — this tool sends the currency codes and amount you enter to a third-party exchange-rate API in order to return a live rate. No personally identifiable information is included in that request.

3. Cookies and Similar Technologies

We use a limited number of cookies to run the Site and, where enabled, to understand aggregate usage through analytics. Full details of the cookies we use, their purpose, and how to control them are set out in our separate Cookie Policy.

4. Legal Basis for Processing

Where we do process personal data (for example, your contact form submission), we rely on the following legal bases under UK GDPR: (a) legitimate interests — to respond to enquiries and keep the Site secure and functioning correctly; and (b) consent — for optional analytics or non-essential cookies, where applicable, which you can withdraw at any time via your browser or cookie settings.

5. How We Use Your Information

Any personal data we hold (principally, contact form submissions) is used only to: respond to your enquiry; improve and maintain the Site; and comply with our legal obligations. We do not sell, rent or trade personal data to third parties for marketing purposes.

6. Sharing and Third Parties

We may share limited technical or usage data with trusted third-party service providers who help us run the Site, such as our hosting provider, analytics provider, and the currency exchange-rate API used by the Currency Converter tool. These providers only process data on our instructions and are required to keep it secure. We do not share personal data with third parties for their own independent marketing purposes.

7. Data Retention

We keep contact form correspondence only for as long as reasonably needed to resolve your query and for a limited period afterwards in case of follow-up, after which it is deleted. Aggregated, non-identifiable analytics data may be retained for longer to help us understand trends over time.

8. International Transfers

Some of the third-party providers we use (for example, analytics or exchange-rate data providers) may process data outside the UK. Where this happens, we expect those providers to have appropriate safeguards in place, such as the UK’s International Data Transfer Agreement or the EU Standard Contractual Clauses, to protect your information to a standard broadly equivalent to UK law.

9. Your Rights

Under UK GDPR, you have the right to: request access to any personal data we hold about you; request correction of inaccurate data; request deletion of your data; object to or restrict certain processing; request a copy of your data in a portable format; and lodge a complaint with the Information Commissioner’s Office (ICO) at ico.org.uk if you believe we have not handled your data properly. To exercise any of these rights, please contact us via our Contact page.

10. Children’s Privacy

This Site is intended for general use by adults researching UK mortgage, property and financial topics. We do not knowingly collect personal data from children.

11. Security

We take reasonable technical and organisational steps to protect any information we hold, including secure hosting and access controls. However, no method of transmission or storage over the internet is completely secure, and we cannot guarantee absolute security.

12. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. The “Last updated” date at the top of this page shows when it was last revised. We encourage you to review this page periodically.
