Clear Handling of Inquiry Data

Privacy Policy

This policy explains how information submitted through this website is handled.

Last updated: September 2, 2026

Information you provide

When you submit a quotation request or contact us, we receive the details you enter, such as your name, work email, company, country or region, product and project requirements, and any message you send.

When you submit a form, we also receive limited technical and submission context, including the source page, page title, submission times, device time zone, browser language, device/browser/operating-system estimates, screen and viewport size, referrer, campaign parameters, Cloudflare request identifier, user agent, and approximate country and time zone supplied by Cloudflare. The inquiry email does not include the visitor's IP address.

How we use information

We use the information to review your request, confirm specifications, prepare a quotation, respond to questions and continue the business conversation you initiated.

Analytics and campaign attribution

We use Google Analytics to understand aggregate website usage and actions such as starting an inquiry, completing an inquiry, opening the quotation form, and clicking our email or WhatsApp contact links.

When a visitor arrives through a tagged campaign, campaign parameters and Google advertising click identifiers may be stored temporarily in the browser session. This allows the original campaign to remain connected to a quotation request after the visitor moves between pages. We do not sell this campaign-attribution data.

Inquiry delivery and security

The quotation form sends inquiry data to a server-side email delivery service. We apply same-origin checks, input limits and a spam-trap field. No online form can guarantee absolute security, so do not submit passwords, payment-card data or other account credentials.

Retention and sharing

We retain inquiry records for business follow-up and recordkeeping for as long as reasonably needed. We do not sell inquiry data. Information may be processed by service providers used to deliver and operate the inquiry service, or disclosed when required by applicable law.

Your choices

You may ask us to correct or delete information you submitted by emailing [email protected]. You can also use browser controls to restrict cookies or clear cookies and session storage, although this may reduce analytics and campaign-attribution accuracy. We may retain limited records when needed for legal, security or legitimate business recordkeeping.
