Privacy Policy

Last updated: May 8, 2026

What information we collect

Extension Cost Calculator only collects the information needed to run the site and respond to enquiries. If you contact us through the contact form, we may receive your name, email address and the message you choose to send.

The site does not offer account registration and does not collect payment details. If analytics are active, we may collect anonymous usage information such as page visits, device type, browser type and general interaction patterns. This is used in aggregate and is not intended to identify individual visitors.

How we use your information

Contact form information is used only to read and respond to your enquiry. We do not use contact form submissions for marketing unless you have clearly asked us to do so.

Analytics information, where used, helps us understand which pages are useful, where the site can be improved and whether the calculator is working properly for visitors. We do not sell personal data.

Cookies

The site may use essential cookies or similar technologies where they are needed for basic website functions. If analytics tools are active, they may use first-party or third-party cookies depending on the service configured, such as Plausible or Google Analytics 4.

Where non-essential cookies are used, visitors should be given clear information about what those cookies do and, where required, a choice before they are set. If analytics or tracking cookies are not active on the live site, this section should be updated to state that the site does not use tracking cookies.

Data retention

Contact form submissions are retained only for as long as needed to respond to and manage the enquiry. As a working default, enquiries should be deleted within 12 months unless there is a clear reason to keep them for longer.

We do not sell personal data. We also do not share personal data with third parties except where it is necessary to operate the website, respond to an enquiry, comply with the law or protect the site from misuse.

Your rights under UK GDPR

Under UK data protection law, you may have rights to access, correct or delete personal data held about you. You may also have rights to restrict or object to certain uses of your data.

To make a data request, please contact us through the website contact page and include enough information for us to identify your enquiry. We may need to ask for further details before acting on a request.

Changes to this policy

We may update this privacy policy from time to time to reflect changes to the site, analytics setup or legal requirements. The page template shows the latest update date, and the current version published on the site replaces any earlier version.
