Privacy Policy
The short version: we collect as little as possible, and the calculator runs entirely in your browser.
Who we are
This website is doubleglazingcostcalculator.co.uk, an independent UK cost-information site. We are not an installer and we do not sell, broker or pass on leads. For anything in this policy, you can reach us at hello@doubleglazingcostcalculator.co.uk.
What we collect
Very little. The site has no user accounts, no contact forms and no marketing cookies. The cost calculator runs entirely in your browser: the figures you enter (property type, window count, style, material) are never sent to our servers, stored or shared.
Our hosting provider keeps standard server logs (IP address, browser type, pages requested, timestamps) for security and capacity purposes, as virtually every website does. These are retained briefly and are not used to identify or profile you.
Cookies
We do not set tracking or advertising cookies, and we do not run third-party analytics scripts. If this changes in future, this policy will be updated first and a consent mechanism added where the law requires one.
If you email us, we will hold your message and address for as long as needed to deal with your enquiry, then delete them. We do not add you to any list.
Your rights
Under UK GDPR you have the right to access, correct or request deletion of personal data we hold about you, and to complain to the Information Commissioner's Office (ico.org.uk). Given how little we collect, the most we are ever likely to hold is an email you sent us.
Changes
Any change to this policy will be published on this page with the date below. This policy was last updated on 4 June 2026.
