Published site notice. This notice describes the current website functions. Service-provider disclosures and external legal review remain incomplete; legal approval has not been recorded.
Necessary site storage
Necessary session and security storage supports form submission, request integrity, and abuse prevention. It is used for the site's requested functions and cannot be disabled through an optional-media choice.
Preference cookie. Name: kfpcba_cookie_preferences. Category: Strictly Necessary. Purpose: stores privacy choices and the policy revision so the site can remember whether optional Analytics and External Media are allowed. Duration: 180 days, unless the user clears browser storage earlier.
Optional analytics
Baidu Tongji and 51LA are optional website-analytics services. Their scripts remain blocked until you allow Analytics in Cookie Settings. They may receive page addresses, referring pages, browser and device information, network metadata and browser identifiers to measure visits and traffic sources. Provider cookies or browser storage may be used after your choice. See the Baidu Tongji privacy policy and 51LA service terms.
You can reject Analytics without losing access to enquiries or engineering-file uploads. Withdrawing Analytics reloads this page to stop the loaded scripts; the consent control also clears matching first-party analytics cookies where accessible. This does not erase information already received by a provider or cookies on a provider-controlled domain.
Optional external media
The external map is an optional-media feature. No map iframe is present in the initial page HTML. The site creates it only after the user allows External Media; withdrawing that category removes it. Selecting Open in Maps is a separate user-initiated visit to the provider.
Retention and choices
The footer's Cookie Settings control remains available so analytics and external-media choices can be reviewed or withdrawn. Application rate-limit records are eligible for cleanup 90 days after they expire. Unsubmitted RFQ files become eligible for cleanup after 24 hours; cleanup runs when the RFQ attachment service handles subsequent requests. Hosting-log retention and a scheduled production cleanup process have not been verified. You can review the privacy notice and use the data request page for information requests.
These cleanup conditions apply only to the application records described here; they do not establish a production hosting-log policy.
Updates and review status
Content updated: 12 November 2026. External legal review and remaining service-provider disclosures are pending. This update does not record legal approval.
