When it is displayed, your browser connects directly to Google’s servers; your IP address and browser information may be processed by Google and transferred abroad. That processing is governed by Google’s own privacy policy. If you prefer not to load the map, you may contact us directly by telephone or e-mail.

10. Advertising and Conversion Measurement

A Google Ads measurement tag provided by Google LLC runs on every page of our website. Because of this tag, your browser connects to Google’s servers when a page is viewed; as a result of that connection your IP address, browser and device information and the address of the page you are viewing may be transferred to Google and processed abroad.

Unless you choose “Accept” in the cookie banner, the tag operates in restricted mode: no advertising cookie is written to your browser, advertising identifiers are redacted, and no personalised advertising takes place.

If you choose “Accept”, advertising cookies are set on the basis of your explicit consent (Article 5/1 of the KVKK); which advertisement brought you to our site, and interactions such as submitting the quotation form or clicking the WhatsApp or telephone link, are recorded as conversions and may be used for remarketing.

Retention: if you consent, the advertising cookies set on our domain are retained for 90 days by default. See our Cookie Policy for details.

Withdrawing consent: you may withdraw consent at any time via the “Cookie preferences” link at the bottom of every page. The advertising cookies on our domain are then deleted and the tag returns to restricted mode. Withdrawal does not affect the lawfulness of processing carried out before it.
