Privacy Policy
We keep data collection to the minimum needed to run this site.
What we collect
Our calculators run in your browser. The figures you enter — bill amounts, roof size, household details — are not sent to us or stored on our servers.
Analytics
We may collect aggregated, anonymous usage statistics to understand which pages and calculators are useful. This does not identify you personally.
Third parties
We do not sell or share personal data with installers, utilities or advertisers. If we ever introduce an optional quote request feature, your details would only be shared with your explicit consent.
Your rights
Under the GDPR you can request access to, correction of, or deletion of any personal data we hold about you. Contact us and we'll action it.
