4. Cookies and external services
Necessary storage supports website security, form operation, cart functions and your privacy choices. Optional analytics, marketing and consent-controlled external media are disabled unless you allow their category. Google Analytics 4 through Google Tag Manager measures website use with Analytics consent, and the OpenAI Ads Measurement Pixel supports advertising attribution with Marketing consent. These services may process browser, device and interaction information and use cookies as described in our Cookie Policy.
The Google Maps frame on the Contact page loads automatically, without a separate permission button, when it approaches the visible part of the page. This connects your browser to Google, which may receive your IP address, browser and device information and interaction data, and may use cookies or similar storage under the Google Privacy Policy. The map is not controlled by our optional cookie categories and can load even if you select Reject all.
For a current list and instructions for changing or withdrawing your optional choices, see our Cookie Policy or select Cookie Settings in the website footer.
5. Who receives personal data
We share personal data only when needed with:
- website hosting, email, IT, cybersecurity and other service providers acting for us;
- YTL personnel and affiliated teams who need the information to respond or deliver a project;
- professional advisers, auditors, insurers, authorities or courts where legally required;
- Google when the Contact page map loads automatically; other external platforms such as Facebook Messenger or WhatsApp when you choose to load or visit those services.
We do not sell personal data.
6. International transfers
YTL is established in China, so information sent through this website may be accessed and processed in China. Some service providers may also process data in other countries outside the European Economic Area or the United Kingdom. Where data protection law requires it, we use an approved transfer mechanism and appropriate safeguards, such as contractual protections, and apply technical and organisational security measures.
You may contact us to request further information about safeguards relevant to your data.
