Welcome to pinzeng.buzz, the public website of Handan Pinzeng Trading Co., Ltd. This Privacy Policy explains how the website and the trading operation behind it treat personal data when a visitor browses the site, sends a message or asks for a demonstration of wholesale catalog and trade inventory systems.
The policy was prepared by the developer team led by PinZeng, the development name attached to the design and build of this website and of the catalog platforms we showcase. Everything described in this document applies to the site you are reading now and to the inquiry channel reachable at care@pinzeng.buzz.
Privacy Policy effective date: this version is current as of 1 January 2026.
The organisation responsible for this website and for the handling of the personal data that arrives through it is Handan Pinzeng Trading Co., Ltd. The registered business address is South End of Beiyou Village, Baizhai Town, Quzhou County, Handan – 056000, China (CN).
We trade in computer integrated systems design and related professional and technical services, with a special focus on wholesale catalog platforms, inventory sync and trade order workflows for regional distributors. Because the business crosses borders, the people who may read your message could sit in the Handan office or work with a route partner in another country.
You can always reach the responsible team at care@pinzeng.buzz or by phone at +12694845445. When you write to us, please tell us the subject of your matter so we can route your request to the right desk without delay.
If you prefer postal mail, address it to Handan Pinzeng Trading Co., Ltd. at the office above.
We aim to collect very little. On most visits we hold no personal data about you at all beyond the routine technical records described below. The data set changes only when you choose to contact us.
We deliberately avoid asking for sensitive categories of data such as health records, religious belief, political opinions or biometric data, because none of it is needed to run a catalog platform.
Personal data reaches us through a small number of deliberate gates. Understanding each gate helps you see exactly where your information is at any moment.
The first gate is the contact form on this website. When you submit the form your details are prepared for delivery to care@pinzeng.buzz. Depending on your device this opens your own email application, which means the network used is that of your own email provider before it ever rests on our side.
The second gate is a direct email or a telephone call. A call to +12694845445 is answered by our trade team, and we keep a written summary of business inquiries so the same question is not asked twice in different weeks.
The third gate is an answered marketing or partnership enquiry where you have given us your card or your details in another context, such as a trade meeting. We add your details to a short, separate partner list only if there is a genuine reason to follow up.
We do not buy lists of names from brokers, and we do not scour public registers to build a mailing list of strangers.
We hold personal data for clear, limited business reasons, each one tied to the service we provide. There is no hidden motive of surveillance or monetisation of your identity.
We hold your name and email to reply to your inquiry and to keep a single thread of that conversation for the follow-up work. If you ask about a catalog build, we hold your data so the same team can see the context of the whole exchange instead of asking you to repeat yourself.
We hold messages and any attached price sheets to prepare an accurate demonstration or proposal for you. Without the contents of your message there is little we could build for you, so retention is a practical matter rather than an ambition to store more than we need.
We hold routine technical logs to protect the website against abuse, to diagnose faults and to understand roughly which pages matter to visitors. We do not assemble a detailed advertising profile from those logs.
Finally, we may keep records to meet legal, accounting and tax duties that apply to a trading company under the jurisdiction where Handan Pinzeng Trading Co., Ltd. is established.
We process personal data on one or more of a small set of lawful bases, and we pick the basis that most honestly describes each activity rather than stretching a single clause to cover everything.
When we rely on legitimate interest we keep the processing proportionate and transparent, and we are glad to explain the reasoning on request.
This website is designed to be light on stored technology. We do not operate a large network of third party advertising cookies, and we do not sell audience data derived from your browsing.
The site may use strictly necessary storage so that a single page can be served correctly and so that the mobile navigation drawer behaves as expected during your visit. Such storage is functional and holds nothing that would let a stranger identify you personally for marketing.
The hosting layer that keeps the site reachable may keep short-lived records for performance and security. Those records are retained for a short window and are then removed automatically, in line with industry practice for a public website with no login accounts.
We do not currently display tracking pixels from advertising platforms on the public pages. If we ever introduce optional measurement tools we will say so plainly in this policy and make the choice a real one for you rather than a default you never see.
Most browsers let you clear stored data, disable new storage or browse in a private window. Because the site works without login, blocking such technology will not remove any member benefit; there is no gated member area at pinzeng.buzz today.
The uses of your personal data are all connected to the trading and technical work of the company. There are no shadow processes running your information through unrelated systems.
We do not use your data for automated decision making that has a major effect on you, and we do not build a profile that scores you for credit or employment while you simply read these pages.
Your data is shared only to the extent necessary to run the website and the trade service you have touched. The list of recipients is short and it is a matter of record.
The hosting provider that serves pinzeng.buzz sees routine technical data in the normal course of keeping the site online. We choose a provider that offers reasonable industry security and that processes hosting data under its own standard terms.
If you become a client, our accounting and legal advisers may see the minimum billing and agreement records needed for their work. That is standard for any trading company and happens under confidentiality.
Where we use cloud email or project tools to organise the work, those tools process messages inside the folders of the trade team. We keep such tools on accounts controlled by Handan Pinzeng Trading Co., Ltd. rather than personal free accounts.
We do not give your personal or commercial data to data brokers, to advertisers, to credit agencies or to mailing-list resellers. If a partner must see your details to complete a delivery we first explain the reason and keep the exposure to the smallest necessary slice.
Trade is international, and Handan Pinzeng Trading Co., Ltd. is established in Quzhou County, Handan, China (CN). Your inquiry may therefore cross national borders as it travels to our team and as our team collaborates.
We ask you not to send data you consider highly sensitive through the contact form. If your matter genuinely involves health, national identity numbers or financial secrecy, telephone us at +12694845445 and we will agree a more controlled channel together before anything moves.
When personal data does cross a border, we apply a consistent internal standard of care that does not drop below what we promise in this policy, and we ask any subcontracting processor to apply a similar duty under a written agreement.
For parties inside the European Economic Area, the United Kingdom or other regions with their own transfer rules, we keep the data flows minimal and we respond in good faith to any request for an explanation of where a specific dataset rests.
We keep personal data no longer than the purpose requires, and we apply different windows to different kinds of record so that nothing lingers without a reason.
Simple inquiries that never turn into business are typically closed from our working folders within two years of the last exchange, at which point we erase the messages. We share this so you know that an old note will not sit in a drawer forever.
Technical log data from the hosting layer is rolled off after a short retention window, normally measured in weeks to months, because the value of those logs is immediate fault finding rather than a permanent profile.
Accounting and tax records that the law requires a trading company to keep are retained for the period set by the applicable rules, which can be several years. Those records are kept for the legal duty and not reused for marketing.
If you become an active trade partner we agree a data retention schedule within the written agreement, so both sides know what stays current and what is deleted when the arrangement ends.
This website sells wholesale catalog and trade inventory systems to businesses and professionals. It is not aimed at children, and our systems are not toys or applications designed to entertain a younger audience.
We do not knowingly collect personal data from children under the age of thirteen. The contact form asks about a trade shelf, a price sheet or a distributor route, topics that a child would have no reason to raise in the course of normal use.
If you believe a child has sent us personal data by mistake, write to care@pinzeng.buzz with a short note and we will act quickly to remove the record from our working files.
The laws of many countries, including the rules that bind companies serving European and United Kingdom visitors, give you a set of rights over the personal data we hold. We honour those rights whether or not you live in a region with a named law.
To exercise any right, write to care@pinzeng.buzz and identify yourself clearly. A genuine request is answered within the window set by the applicable law, normally about one month, without charge and without any penalty to the service you receive.
We treat security as a set of habits rather than a single padlock. The measures below together reduce the risk that personal data is lost or read by someone who should not see it.
No method is perfect. If a security event ever touches your personal data in a way the law would require us to report, we will tell you as soon as we can confirm the facts and give you a clear next step.
We may update this Privacy Policy as the website, the systems or the law evolves. Whenever we change it we adjust the effective date at the top of the page so you can see that a new version is in force.
Meaningful changes will be flagged in plain language, for example inside the opening summary, rather than buried in a long legal wall. If a change would affect an existing active arrangement with a client, we raise it in writing through the normal business channel as well.
Because this policy is a live document, we encourage you to review it when you next need to rely on what it says. The date printed at the top is the honest reference point for which version governs your visit today.
Historical versions are available from the legal team on a request to care@pinzeng.buzz.
If you believe we hold your data unfairly or have handled it carelessly, the first and fastest route is to tell us directly. Most concerns are settled with a plain conversation because they rest on a misunderstanding of what was collected or why.
You are never penalised for raising a concern. Our trade desk wants to sell catalog systems to people who trust how the company behaves, and a clean answer to a privacy question is part of that trust.
This Privacy Policy should be read together with the Terms of Service, which govern the wider use of the website. Where the two documents address the same record, the control of a visitor about their own data is described here, while the general conditions of using the site are described in the Terms of Service.
The developer of this website and of the catalog concept is PinZeng. The operating company that stands behind the service is Handan Pinzeng Trading Co., Ltd., whose registered address is South End of Beiyou Village, Baizhai Town, Quzhou County, Handan – 056000, China (CN).
For any question about your personal data you may contact us at care@pinzeng.buzz or by telephone at +12694845445 during business hours. For postal correspondence, use the registered address above.
