This Privacy Policy explains how Shandong Longchang Chemical Co., Ltd. (“Longchang Chemical”, “we”, “us”) handles information collected through longchangextracts.com and related business inquiries.

Information we collect
- Business inquiries: the name, email address, telephone number, company, product specifications, quantity, destination and other information you choose to provide through a form, email or telephone conversation.
- Technical and security information: IP address, browser and device information, requested pages, dates and times, and related server or security records used to deliver the website and detect abuse.
- Website usage information: page visits, referral information and interactions such as quotation-link clicks, collected through Google Analytics and similar website measurement functions.

The inquiry form is intended for commercial and technical questions. Please avoid including patient records, medical histories, payment-card details, identity documents or other information that is unnecessary for your inquiry.
How we use information
We use information to answer requests, prepare quotations, discuss specifications and documentation, manage business relationships, maintain website performance, understand how the website is used, prevent spam and misuse, and meet applicable legal obligations. Sending an inquiry does not subscribe you to unrelated promotional messages.
Where applicable data-protection law requires a legal basis, processing may be based on steps you request before entering a contract, performance of a contract, our legitimate interests in running and protecting the business, compliance with legal obligations, or your consent. Where processing relies on consent, you may withdraw that consent without affecting processing already carried out lawfully.
Cookies and similar technologies
The website and its service providers may use cookies, browser storage, web beacons, IP addresses and other identifiers. These support functions such as authentication, language selection, browser security checks, traffic measurement and, when enabled, advertising. A cookie may be set by this website or by a third-party provider whose service appears on a page.
You can manage cookies through your browser settings, including deleting stored cookies and blocking future cookies. Some site functions may be affected. Where a consent message or privacy-settings control is shown, use that control to choose or change the optional services you allow. Browser controls and advertising opt-outs serve different purposes; disabling personalized advertising does not necessarily disable all cookies.
Google Analytics
We use Google Analytics to understand visits and website interactions. Google may process device and browser information, online identifiers and usage events through this service. Learn about Google’s use of information from partner sites and Google’s Privacy Policy. Google also provides an Analytics opt-out browser add-on.
Google advertising, when enabled
This section applies on pages where Google advertising is enabled. Third-party vendors, including Google, use cookies to deliver advertisements based on previous visits to this website or other websites. Google’s advertising cookies allow Google and its partners to select advertisements using visits to this and other sites across the internet. Advertising services may also use web beacons, IP addresses and other identifiers to deliver, measure and protect advertisements.
You can manage personalized Google advertising through My Ad Center. You can also learn about participating companies and their opt-out options at YourAdChoices. These choices do not necessarily stop advertisements; they affect how eligible advertisements are personalized.
Where other advertising vendors participate, their identities, relevant policies and available choices are provided through the applicable advertising privacy or consent information. See Google’s advertising technology information for further details. Advertising and related storage must operate subject to the choices and consent requirements applicable to the visitor’s location.
Service providers and other disclosures
Information may be processed by providers that support hosting and content delivery, email delivery, form processing, security, analytics and advertising. Our hosting and delivery infrastructure includes Hostinger. An inquiry may also be shared with relevant Longchang personnel and, where needed to respond to your request, a manufacturer, laboratory or logistics provider involved in that request. We limit such sharing to information relevant to the purpose.
We may disclose information when required by applicable law, to respond to lawful requests, or to protect rights, safety and the security of our services. External links and embedded content may connect to services with their own privacy practices. Review those services’ policies before providing information to them.
International processing
We are based in China and work with international service providers and business partners. Information may be processed in China and other countries where those organizations operate. Applicable safeguards and transfer requirements depend on the information, destination and laws that apply. Contact us if you need information about the handling of your particular inquiry.
Retention and security
We retain information for as long as it is reasonably needed for the purposes described here, including responding to inquiries, maintaining relevant business records, resolving disputes and satisfying legal obligations. Retention depends on the type of record and the business or legal need. Security and anti-spam records may follow different retention periods from commercial correspondence.
We use access controls and technical and organizational measures to protect information. No transmission or storage method provides an absolute guarantee of security.
Your choices and requests
Depending on applicable law, you may have rights to request access, correction, deletion or a copy of your information, to restrict or object to certain processing, and to withdraw consent. Email info@longchangchemical.com with enough detail to locate the relevant record. We may need to verify your identity before acting, and legal recordkeeping requirements may limit deletion. You may also have the right to contact the relevant data-protection authority.
Children
This website is intended for business and professional audiences and is not directed to children. If you believe a child has provided personal information unnecessarily, contact us so that we can review and address it.
