Rejecting optional technologies does not prevent you from viewing machine information or contacting YONGFA. Previously loaded third-party content is removed when you withdraw its permission.
Necessary storage
yongfa_cookie_consent is a first-party cookie that remembers whether you allowed analytics, advertising and external media. It stores a consent version, category choices and update time for 180 days. It is used only to remember and respect your privacy choice.
yongfa_language_choice records your manual language preference in browser local storage. Explicit navigation and your current selection take priority over automatic detection. yongfa_language_auto_checked is session storage that records whether the initial language check has been handled. It prevents automatic detection from overriding later navigation. Neither language-storage item is used for advertising or cross-site tracking.
External media
Product and factory videos are provided through YouTube. The YouTube player is not loaded until you allow external media. When it loads, your browser connects to Google and Google may receive information such as your IP address, device and video interaction.
The site uses YouTube's privacy-enhanced embed domain, but permission is still requested before the player loads. See how Google uses information from partner sites, and Google's Privacy Policy.
Analytics
No Google Analytics or equivalent analytics tag is currently active on this website. The consent setting is prepared so analytics remains disabled unless you allow it if measurement is introduced later. This policy will be updated before such a tool is activated.
Advertising
No Google Ads conversion, remarketing or personalised advertising tag is currently active on this website. Google Consent Mode defaults advertising storage, advertising user data, advertising personalisation and analytics storage to denied. If advertising measurement is introduced, consent choices will be sent to Google and this policy will identify the active services and retention periods.
Email and WhatsApp links open services that you choose to use. Those providers process activity under their own privacy and storage policies.
