Useful insights.
Your choice.

01 / Optional analytics

Accept or reject. The site still works.

We use Google Analytics 4 (GA4) only after you choose Accept analytics. Before acceptance, and when you reject analytics, our analytics module does not load Google's analytics script or send analytics requests to Google. Rejecting analytics does not restrict browsing or WhatsApp contact links.

Use the Analytics preferences control to review your current choice, accept, reject or withdraw consent later. A choice is saved in your browser's local storage so it can be applied on future pages and visits in that browser. Clearing site data, using another browser or using another device may require a new choice.

Our analytics module respects the browser's Do Not Track (DNT) and Global Privacy Control (GPC) signals. When either signal requests no tracking, analytics stays disabled even if a previous acceptance was saved. If local storage is unavailable, analytics stays disabled.

02 / Limited measurement

Visits and contact-button clicks.

After acceptance, GA4 helps us understand page visits, general traffic sources and aggregate device or browser information. The analytics service receives technical connection information as part of a request. We do not add names, email addresses, contact-message content or form-field values to our analytics events.

Page addresses and referring-page addresses are sent without query strings or URL fragments. A WhatsApp button click is recorded as whatsapp_click, with the page path, contact method and a general button location such as header, floating button or product page. We do not send the WhatsApp destination telephone number, full WhatsApp link or prefilled message in that event.

This integration does not enable Google advertising storage, Google signals or ad-personalization features. It is not used to launch paid advertising. Automatic enhanced measurement is not part of this integration; page views and WhatsApp clicks are the measurements we intentionally configure.

03 / Browser storage

A remembered choice. Limited identifiers.

The analytics preference itself is stored in local storage, separate from Google cookies. It is used to remember whether analytics is accepted or rejected, not to identify you in reports.

After acceptance, GA4 may set first-party identifier cookies such as _ga and a measurement-specific _ga_ cookie. We configure their lifetime to 90 days and do not extend that lifetime on each visit. Browser settings may shorten or otherwise restrict cookie storage.

Withdrawing consent stops future analytics events from our module and removes the GA cookies for this website and this measurement configuration. It does not remove unrelated site cookies, erase data already received by Google, or recall requests already in flight. You can also remove cookies and local storage using your browser's site-data controls.

04 / Service providers

Understand the external services.

When analytics is accepted, measurement data is sent to Google Analytics for reporting in our Google Analytics account. Google's processing and international infrastructure are described in the Google Privacy Policy and Google's Analytics data and privacy information.

WhatsApp contact links take you to an external WhatsApp service. Your use of that service and any messages you send are separate from our website statistics and are subject to WhatsApp's privacy policy. Choosing a WhatsApp link does not require acceptance of our website analytics.

This notice describes the website analytics implementation. It does not replace the information or terms shown by those external services.
