5. Cookies

We use first-party cookies and similar technologies for site functionality, session handling, language preference, security, analytics, and advertising measurement.

We may use Google Tag Manager, Google Analytics 4, Google Ads conversion tracking, remarketing tags, and similar tools to understand how visitors interact with our website, measure advertising performance, and improve lead quality. These tools may process page URLs, browser information, approximate location, referrer, advertising click identifiers such as gclid, wbraid or gbraid, and website event data such as form submissions or contact clicks.

If legally required in your region, we will use a consent mechanism such as Consent Mode or a cookie banner before activating non-essential analytics or advertising tags.

6. First-Party Visitor Analytics

We may operate our own website visitor analytics to understand B2B purchasing interest and improve sales follow-up. This may include recording page visits, visit time, referrer, approximate session duration, page navigation path, device and browser information, approximate location derived from IP address, and whether a visitor later submits an inquiry. We use this information for website performance review, lead quality analysis, fraud or abuse prevention, and sales response prioritization. We do not use this data to collect payment information, passwords, or sensitive personal categories, and we do not sell visitor analytics data.

7. Advertising and Conversion Data

When you arrive from an advertisement, we may store campaign parameters such as utm_source, utm_medium, utm_campaign, utm_term, utm_content, gclid, wbraid or gbraid together with your inquiry. This helps us understand which campaigns generated qualified business inquiries and improves future advertising relevance.
