Cookies and your choices.

This page explains the current use of cookies on the Yolcubal Engineering website. Last updated: 8 October 2026.

Essential session cookie

yolcubal_session: a first-party session cookie used for secure contact and career forms, the site assistant’s conversation session and administrator sessions. It is created when a form or the administration panel is opened, or when the first message is sent to the assistant, and lasts for the browser session. Your browser’s session restore settings may extend this period.

Remembering your cookie choice

yolcubal_consent: a first-party cookie storing your acceptance or rejection, preference version and expiry. It is retained for up to 180 days after your choice, so we do not ask again on every page.

Optional experience cookie

yolcubal_motion: remembers your choice to pause the three-dimensional visual. It is used only after you allow experience preferences. This first-party cookie lasts for the remaining duration of your permission, up to 180 days, and is deleted when you withdraw permission. Without permission, you can still view the model and pause it on the current page.

Analytics and advertising

This version does not use analytics, advertising or third-party tracking cookies. The model, cookie panel and local fonts do not load third-party tracking services. External websites have their own practices when you open their links.

Changing your choices

Use Cookie preferences in the footer to reopen the panel, reject the optional cookie or change your permission. You can also delete or block cookies in your browser settings. Blocking essential cookies may prevent secure forms and administrator sessions from working.
