Privacy Policy
What information Design Mix Concrete processes, why advertising may use cookies, and what choices visitors have.
Free calculator inputs
Inputs used in the free calculators are processed in your browser. We do not ask you to create an account to use the free calculation tools.
Paid reports
If you purchase a report, information needed to fulfil that purchase can include the email address you confirm, an optional name, the calculation/report data needed to generate the document, and payment identifiers returned by the payment provider. Payment-card or bank credentials are entered into the payment provider's checkout and are not stored by Design Mix Concrete.
Google advertising, cookies and similar technologies
Design Mix Concrete uses Google AdSense to fund free engineering content and calculators. Google and its advertising partners may use cookies or similar technologies to deliver, measure and protect advertising. Depending on your location and consent choices, ads may be personalised or non-personalised.
You can review Google's advertising controls through My Ad Center. You can also learn how Google uses information from sites and apps that use its services through Google's own privacy documentation.
Consent in the EEA, United Kingdom and Switzerland
Where advertising consent is required, the site must use a Google-certified consent management platform for the advertising choices presented to visitors. The consent message and available options can vary by jurisdiction and by Google's current advertising requirements. Your consent choice is separate from the region preference described below.
Advertising should not be activated for affected visitors unless the required consent configuration is enabled in the site's Google advertising account.
Region preference
If you select a region from the site menu, a first-party cookie named region may remember that choice for up to one year. It is used to make regional navigation easier; it is not used by Design Mix Concrete to build an advertising profile.
Third-party services
The site may use Cloudflare for hosting/security, Google for advertising, Razorpay for supported payments, and email/report-delivery infrastructure when a paid report is requested. Those providers process information under their own terms and privacy policies where applicable.
Data minimisation and retention
We aim to collect only the information needed to operate the requested feature. Free calculator inputs are normally handled in the browser. Information associated with a paid report may be retained as reasonably necessary for delivery, transaction records, fraud prevention, support and legal/accounting obligations.
Your choices and questions
You can use the free engineering content without purchasing a report. Browser controls can be used to manage first-party cookies, and advertising-consent controls may be presented where required. For privacy questions or requests concerning information handled directly by Design Mix Concrete, email support@designmixconcrete.com.
