1. The company and this notice
This privacy policy belongs to Hong Kong Yunyou Network Technology Co., Limited, a company registered and operating from the address given below. The company designs computer systems and network architecture for professional, scientific and technical clients and for other regional businesses across Hong Kong and south China. Where this document refers to the company, the team, us or we, it means Hong Kong Yunyou Network Technology Co., Limited and the people it employs.
The purpose of this notice is to be honest about the small amount of personal data that passes through our doors. Most of what the company touches is infrastructure, code and records rather than personal detail, because the products we build are cloud platforms and network systems. Even so, when you contact us, commission a system, or browse this website, some information about you moves across our desks. We believe you deserve to know what that is and what we do with it.

2. What this policy covers
This policy covers personal information that the company handles in four settings. The first setting is this public website, including the service descriptions, the route information and the contact pages you may read. The second setting is the enquiry and booking process, when you write to help@yunyou.buzz, call +85259433476, or send a message through our contact form. The third setting is the delivery of contracted services, when a client asks the company to migrate workloads, run a private gateway or watch a cluster. The fourth setting is routine business correspondence such as invoices, project plans and meetings.
The policy does not cover the content of the systems the company operates on a client behalf. When the company runs a cloud platform for a business, the business files, customer lists and application data inside that platform belong to the business, and the laws that govern that business apply to them. If you are a customer of one of the businesses the company serves, that business remains the data controller for your records. The company acts as the operator of the machinery underneath, and that role is described separately in our Terms of Service.
3. About the developer YunYou
The systems described on this website were designed and are maintained by YunYou, a developer whose name appears in the original specifications behind these pages. YunYou is the engineer responsible for the shape and correctness of the network and cloud architecture you read about here, and the company stands behind that work. Mentioning the developer name in this policy is a matter of transparency, so that the people who read it understand who designs the technical systems behind the service.
This mention is a simple statement of authorship. It is not a request, an offer or a modification of any term in this policy or in the Terms of Service. The developer works within the legal structure of the company, and all rights, responsibilities and protections described elsewhere in this document belong to the registered legal entity named at the start of this policy.
4. Information we collect
The company collects only the information that its work genuinely requires. When you browse the public pages of this website, our systems record a small technical footprint that helps us keep the site running safely. That footprint can include the internet protocol address of your device, the type of browser and operating system you use, the pages you view, and the time of your visit. This kind of information is gathered in the ordinary course of serving any website and is usually held in a general and anonymous way.
When you contact the company, we collect the details you choose to share: your name, your email address, your telephone number if you offer it, the name of the business you represent, and the content of your message. If you ask us to design or operate a system, we may collect professional details such as your role, your reporting line, the region your business covers, and your preferences about how the work should run. The company does not collect special categories of data, and it never asks for sensitive personal information such as health, religion or political views as part of its ordinary business.
5. How we collect it
Most personal information reaches the company through a small number of clear paths. The first is words we exchange: a message sent through the contact form, an email to help@yunyou.buzz, a telephone conversation on +85259433476, or a meeting where you describe your situation. In those exchanges, the personal details arrive because you provide them, and we keep only what the conversation requires.
The second path is technical and automatic. When a browser visits this website, the server receives standard signals about the request so it can deliver the right page. Logs of those requests give the company the technical footprint described above. The third path is through the operation of our services, where a business client may make records available to us so we can migrate or monitor them. In that third path, the company is a processor acting under the instructions of the business client, and any personal data within those records is handled under the rules of that client agreement.
6. How we use the information
The company uses personal information for reasons that follow directly from the task at hand. We use the details from an enquiry to answer it, to prepare a proposal, to schedule a review and to tell you honestly about what the company can and cannot carry. We use business contact details to maintain the relationship: to send invoices, to arrange project work, to issue reports from the Network Operations Center and to keep a contracted client informed about the health of a platform the company watches.
We use the small technical footprint from the website to keep the site secure, to diagnose faults and to understand, at a general level, which pages people find useful. The company does not sell personal information, and it does not rent its client lists to anyone. We do not use the details you share in this enquiry process to market unrelated companies at you, and we do not build long behavioural profiles from your browsing. When we do send a note about our own work, it is offered and can be refused without penalty.
7. The legal basis for processing
The company follows the data protection rules that apply wherever it does business, including the personal data laws of Hong Kong and of any market it serves. Different tasks rest on different justifications, and the company is clear about which one applies in each context. Where we respond to an enquiry you have raised, we act on your request. Where we prepare a proposal you asked for, the foundation is the same interest you opened when you wrote to us.
Where we operate a contracted system, the basis is the contract itself, together with the lawful demands of running infrastructure for a business. Where we keep records to satisfy legal or accounting duties, the basis is a legal obligation on the company. And where we operate the website securely and improve our own honest marketing, we rely on the legitimate interest of running a sound business, balanced carefully against your own interests and freedoms. The company will avoid any use of your information that would outweigh your rights as an individual.
8. Storage and data location
Personal information that the company holds is stored on infrastructure the company controls or that is governed by written agreements with trusted providers. For a Hong Kong based engineering firm serving south China, data often sits in locations close to the work itself, so that latency stays low and access remains dependable. The company will not move your information to a location without making sure, before the move, that it can offer protections consistent with this policy.
Access to stored information is limited to the people who genuinely need it for their work, and those people are bound by confidentiality. The company reviews where each collection of data sits from time to time, so that a record collected for one purpose does not drift unnoticed into another region or another system. Should the location of a store change, that change is made deliberately and recorded, and this policy continues to describe the safeguards around the data at its new home.
10. How we keep it secure
The company treats the security of personal information as an engineering problem rather than a slogan. Transport of data across the public network is encrypted, accounts that can reach stored information are protected and reviewed, and access is granted on the smallest footprint that still lets a task be done well. Because the company designs network and cloud systems for a living, the crews that do that work are the same crews who would notice a weakness in someone else perimeter, and they apply that eye to our own house.
Protection does not end at the edge of a server. The company keeps written procedures for handling an incident, backs up critical records to more than one place, and rehearses recovery so that even a serious event does not become a permanent loss. No measure is absolute, and no organisation anywhere can promise perfect protection against every determined attack. The company is honest about that limit, but it works hard every day so that the records you trust us with sit behind real, tested and attentive defences rather than hopeful intentions.
12. Marketing and consent
Where the company wishes to send you a message about its own work, it does so only in ways that respect your choice. For business clients and genuine enquirers, occasional notes about the services the company offers may be expected as part of a working relationship, but every such note carries a quiet and easy way to opt out. Where the law of your market requires a clear consent before any promotional message, the company obtains that consent first and records the fact that you gave it.
You can withdraw a consent or object to promotional contact at any time by writing to help@yunyou.buzz or by using the unsubscribe instructions inside any message we send. A decision not to receive marketing never affects the service the company provides under a contract, and it never leads to a worse outcome in an enquiry you have already opened. The company would rather offer one useful, wanted note now and then than annoy you with a stream of hopeful offers, and that restraint is part of the way we run a respectful business.
13. Your rights
Depending on where you live, you hold a bundle of rights over the personal information the company keeps about you. You may ask to see the records the company holds, to learn how they are used, and to receive a copy in a readable form. You may ask the company to correct an entry that is wrong or incomplete. You may ask for the deletion of information the company no longer needs, subject to the limits set down by law, and you may ask to restrict how certain information is used while a question about it is settled.
You may also object to processing that rests on the company legitimate interest, and you may ask for your information in a portable form where the circumstances allow it. Where the company relies on your consent, you can withdraw that consent at any time without penalty. If you believe the company has handled your information wrongly, you may also address a complaint to the data protection authority of your own market. To exercise any of these rights, contact the company through the details at the bottom of this policy, and we will respond within the period the law requires and, wherever possible, sooner.
14. Privacy for children
The company website and the services it describes are built for businesses and for adults who make decisions about systems, networks and procurement. They are not directed at children, and the company does not knowingly collect personal information from a child under the age of sixteen. If you believe that a child has given this company personal information without the consent required by law, please contact us at help@yunyou.buzz and we will remove the information promptly.
Because the company rarely interacts with children at all, cases of this kind should be extremely rare. Even so, the policy states the point plainly so that any parent or guardian who is worried about a young person browsing the professional content on these pages knows what the company does and does not hold. Where an adult operates a system on behalf of a younger member of the family is not a situation this website creates, and the company will not search for such information on its own initiative.
15. Retention and deletion
The company holds personal information only as long as a genuine need exists. An enquiry is kept while we answer it and, if we need to refer back to it for a short while afterwards, for the time that purpose reasonably requires. A contracted relationship keeps its supporting records for as long as the contract runs and then for the further period that accounting and legal rules demand. Website logs and other technical records are held on short schedules and are discarded when they have served their safety purpose.
When the reason for holding information has ended, the company deletes it or removes it from active use in a careful way. Deletion means the records are erased or rendered unusable so they can no longer identify you. The company reviews its stores on a regular rhythm so that data does not quietly grow old. Where a legal obligation forces the company to keep a record longer than the business need would suggest, that record is kept to the minimum the law allows and is protected under the security measures set out earlier in this policy.
16. International transfers
Because the company serves clients across Hong Kong and south China, and because its professionals may work from more than one market, personal information can on occasion move across a border. Where that happens, the company makes sure the transfer is lawful and that the information keeps the protection this policy promises. Transfers within the region the company serves are governed by the rules that bind the company and its trusted partners.
If information must go to a country that does not carry the same data protection rules as the market where you sit, the company first attaches safeguards written into its agreements, so the data does not lose the protection simply because it crossed a line on our map. You may ask the company for a description of these safeguards when a transfer touches your information. The honest goal is that your details should be no less safe for moving, and that a border in geography should never become a loophole in protection.
17. Changes to this policy
The company may revise this privacy policy from time to time to reflect changes in its services, in the law or in the way information should be handled. When a change is made that could matter to you, the updated version is placed on this page and is given a fresh date so you can tell when it last changed. Significant changes are highlighted so the difference is easy to see rather than buried in a long legal document.
Because this is a living document, the company encourages anyone who shares its details to glance back at this page now and again, particularly after a service changes or before you enter into a new arrangement. Where a change requires a fresh consent from you under the law of your market, the company will ask for that consent rather than assume it. Continued use of the website or of a service after an update does not affect any right you already hold under an earlier version of this policy, and the version that was in force when you provided information remains relevant to how that information is treated.
