Privacy Policy

Lingfeng Machinery Co., Ltd. is a manufacturer of plastic bag making machines based in Ruian, Zhejiang, China. We operate this website primarily to present our products, share technical resources, and respond to business inquiries from buyers, distributors, and partners worldwide.

We respect your privacy and process personal data only where we have a lawful basis to do so. This policy applies to information collected through our website, inquiry forms, email, phone, WhatsApp, live chat, and other channels that link to this page.

Depending on how you interact with us, we may collect the following categories of information:

• Contact and identity details — name, company name, job title, country or region, email address, phone number, and messaging identifiers (such as WhatsApp).
• Inquiry and commercial information — machine type, production requirements, bag specifications, budget notes, purchase timeline, and other details you provide in forms or correspondence.
• Technical and usage data — IP address, browser type, device type, operating system, referring URL, pages viewed, session duration, and approximate location derived from IP.
• Cookie and analytics data — preferences, consent choices, and aggregated site usage collected through cookies and similar technologies (see Section 04).
• Communications — records of emails, chat messages, call notes, and support requests related to quotations, orders, installation, or after-sales service.

Where required by applicable law, we will obtain your consent before collecting sensitive personal data. Most information we receive is voluntarily submitted by you when requesting a quote or contacting our sales team.

We use personal information for legitimate business purposes, including:

1. Responding to inquiries, preparing quotations, and communicating about machine specifications, delivery, installation, and after-sales support.
2. Operating, maintaining, and improving our website, including troubleshooting, analytics, and security monitoring.
3. Sending service-related messages you request or reasonably expect, such as replies to your contact form submission.
4. Complying with legal obligations, enforcing our terms, and protecting the rights, property, and safety of Lingfeng, our customers, and the public.
5. With your consent where required, sending product updates, trade-show invitations, or marketing communications. You may opt out at any time.

We do not sell your personal information. We do not use automated decision-making that produces legal or similarly significant effects without human review.

Our website uses cookies and similar technologies to enable core functionality, remember preferences, measure traffic, and improve user experience. When you first visit, you may see a cookie notice allowing you to accept or manage non-essential cookies.

Types of cookies we may use include:

• Strictly necessary cookies — required for site security, load balancing, and basic navigation.
• Functional cookies — remember language, region, or form progress.
• Analytics cookies — help us understand how visitors use pages such as product listings, resource downloads, and contact forms.
• Marketing cookies — only where enabled, to measure campaign performance on third-party platforms.

You can control cookies through your browser settings. Disabling certain cookies may limit some site features. For questions about our cookie practices, contact us using the details in Section 08.

We share personal information only when necessary and with appropriate safeguards:

• Service providers — hosting, email delivery, CRM, analytics, live chat, and IT support vendors that process data on our behalf under contractual confidentiality obligations.
• Authorized partners — local sales agents or service partners in regions such as Peru, Mexico, Saudi Arabia, Russia, and India, when needed to respond to your inquiry or provide installation support.
• Legal and compliance — regulators, courts, or law enforcement when required by applicable law or to establish, exercise, or defend legal claims.
• Business transfers — in connection with a merger, acquisition, or asset sale, subject to continued protection of your data.

Because Lingfeng is based in China and serves customers globally, your information may be transferred to, stored in, or accessed from countries other than your own. Where required, we implement appropriate safeguards for cross-border transfers.

We retain personal information only for as long as needed to fulfill the purposes described in this policy, unless a longer retention period is required by law or legitimate business needs (for example, warranty records or contract archives).

Typical retention periods:

• Website inquiry and quotation records — up to 5 years after last meaningful contact, unless you request earlier deletion and no legal hold applies.
• Customer and order-related records — for the duration of the business relationship and applicable statutory limitation periods.
• Analytics logs — generally aggregated or anonymized within 14 months.

We implement administrative, technical, and physical safeguards designed to protect personal data against unauthorized access, loss, misuse, or alteration. No method of transmission over the Internet is completely secure; please avoid sending highly sensitive credentials through unsecured channels.

Depending on your location, you may have rights to:

• Request access to the personal information we hold about you.
• Request correction of inaccurate or incomplete data.
• Request deletion of your data, subject to legal or contractual exceptions.
• Object to or restrict certain processing activities.
• Withdraw consent where processing is consent-based, without affecting prior lawful processing.
• Receive a copy of your data in a portable format where applicable.
• Opt out of marketing emails by using the unsubscribe link or contacting us directly.

We may need to verify your identity before responding. We aim to reply within 30 days, or within the timeframe required by applicable law. If you are in the EU/EEA, UK, or other jurisdictions with a supervisory authority, you may also lodge a complaint with your local data protection regulator.
