The essential form session
The PHP enquiry handler uses a session cookie to associate a request with its security token and prevent rapid repeat submissions. This cookie is part of operating the form, not a cross-site advertising identifier.
Temporary tool selections
The scope desk keeps its selections in the current page. It does not use localStorage to preserve answers. The FAQ search, system explorer and photograph dialog also reset when the page is reloaded.
Your browser controls
You can remove cookies with your browser’s site-data settings. Removing the form cookie may invalidate a loaded token, so reload before submitting. Reading the information pages does not require sending an enquiry.
Local resources and external links
Bootstrap, jQuery, authored code and photographs are served from the website’s own files. The supplied pages contain no third-party analytics or marketing scripts. When you follow an official-source link, that separate service can apply its own storage practices.
If functionality is unavailable
A blocked security session or a failed network request prevents a successful form submission. The interface retains your entered text and reports the problem. Copy a message before reloading if you want to keep it.
