Privacy Policy

1. Information we collect

• Enquiry & consultation details— when you submit the Request a Consultation / RFQ form or a calculator’s “email me this report” gate, we receive the name, company, email, phone, service interest, and any message you provide.
• Calculator inputs — engineering calculators run entirely in your browser; their inputs are not sent to our servers unless you choose to email yourself a report.
• Privacy-friendly analytics — we measure aggregate, anonymised usage (pages viewed, broad device type) without advertising or cross-site tracking cookies to understand what content is useful.
• Standard server logs — like any website, our servers record technical data such as IP address and browser type for security and reliability.

2. How we use it

We use your information to respond to your enquiry, scope and prepare quotations or BOQs, follow up on a project, and improve our website and services. We rely on your consent and our legitimate interest in serving prospective and existing clients.

3. Sharing & disclosure

We never sell or rent your information. We share it only with our internal sales/CRM systems to follow up with you, and with trusted service providers that operate our site and email delivery on our behalf under confidentiality. We may disclose information where required by law or to protect our rights.

4. Cookies & tracking

Our analytics are cookieless and do not track you across other websites. We do not use advertising cookies. Essential cookies may be used only where needed for core site security and functionality.

5. Data retention

We keep enquiry information only as long as needed to handle your request and for reasonable follow-up, plus any period required by law, after which it is deleted or anonymised.

6. Security

The site is served over HTTPS and access to enquiry data is restricted to authorised staff. No method of transmission is perfectly secure, but we take reasonable technical and organisational measures to protect your information.

7. Your rights

You may ask us to access, correct, or delete the personal information you have given us, or to stop contacting you. Email [email protected] and we will action your request.

8. Children

This site is intended for businesses and professionals and is not directed at children.

9. Changes to this policy

We may update this policy from time to time. The “Last updated” date above reflects the latest revision.
