This Privacy Policy explains how Quanwen Technology Limited collects, uses, stores, and protects personal information when you visit this website or engage with our computer systems design and related services. We are committed to handling your information with care, transparency, and respect, and we have written this policy so that you can understand exactly what happens to the data you share with us.
The website and the services available through it are developed and operated by the developer Quanwen on behalf of Quanwen Technology Limited. We act as a responsible steward of the limited information we receive, and we never sell, rent, or trade personal information to third parties for their own marketing purposes.
By using this website or contacting us, you acknowledge that you have read and understood this policy. If you do not agree with any part of it, please discontinue use of the website and contact us with any questions using the details provided at the end of this document.
Quanwen Technology Limited is a company engaged in computer systems design and related services within the professional, scientific, and technical services sector. Our work spans computer integrated systems design, system architecture, data services, migration, and ongoing technical support for organizations of all sizes.
Our registered office is located at Rm 5042, 5/F, YAU LEE CTR, 45 HOI YUEN RD, Kwun Tong, Hong Kong (HK). We operate the website located at https://www.tontop.buzz, which is the primary point of contact for information about our services and for enquiries from prospective clients.
For the purposes of applicable data protection law, Quanwen Technology Limited is the data controller responsible for the personal information described in this policy. Any correspondence regarding privacy matters can be directed to feedback@tontop.buzz.
This policy applies to the personal information we collect through this website, through email and telephone communications, and through any engagement with our services. It also applies to information provided by individuals who submit enquiries, request a demonstration, or correspond with our team.
This policy does not apply to third party websites that may be linked from this website. When you follow a link to an external site, that site has its own privacy practices, and we encourage you to review the privacy policy of each website you visit. We are not responsible for the content or privacy practices of any website we do not operate.
We review this policy regularly and update it when our services, our data practices, or applicable law changes. The date shown at the top of this page indicates when the policy was last revised.
We collect only the information that is necessary to operate our website and to respond to enquiries about our services. The categories of information we may collect are described below, and we aim to keep the amount of data we hold to a practical minimum.
When you contact us, we may collect your name, email address, telephone number, the subject of your enquiry, and the content of any message you send. When you request a demonstration or ask about a project, we may also collect details about your organization and the nature of the work you are considering.
When you browse this website, our hosting infrastructure may automatically record technical information such as your internet protocol address, browser type, operating system, the pages you view, and the date and time of your visit. This information is used for security, performance, and aggregate analytics purposes.
We do not collect sensitive categories of personal data through this website, and we do not intentionally gather financial account numbers, government identifiers, or other highly sensitive records from visitors. We ask that you do not include such information in any message you send through our contact form.
We collect personal information through a small number of clearly identified channels. First, we collect information that you voluntarily submit through our contact form, by email, or by telephone. Second, we collect limited technical information automatically as you navigate the website, as described in the previous section.
We may also receive information from third parties in the ordinary course of business, for example when a service provider or a professional contact refers an enquiry to us. In every case, we collect only what is relevant to providing our computer systems design and integration services, and we do not use hidden or deceptive methods to obtain data.
You are under no obligation to provide personal information, but certain information is required for us to respond to an enquiry. If you choose not to provide the requested details, we may be unable to answer your question or provide a demonstration of our services.
We use the personal information we collect for a limited and clearly defined set of purposes. Primarily, we use your details to respond to your enquiries, to provide the information you request, and to communicate with you about our services. This includes arranging demonstrations, preparing estimates, and answering questions about systems design and integration.
We also use information to operate, maintain, and improve our website, to understand how visitors use it, and to protect it from misuse or unauthorized access. Aggregate and anonymized analytics help us refine the content and structure of the site, but such analytics do not identify you personally.
Finally, we may use your information to comply with legal obligations, to enforce our terms of service, to resolve disputes, and to protect the rights and safety of our organization and our clients. We do not use personal information for purposes unrelated to those described in this policy without first informing you.
Where we use aggregated or anonymized information for analytics, we take steps to ensure that the information cannot reasonably be used to re-identify an individual. We do not combine your personal information with other data sources in a way that would undermine the expectations set out in this policy, and we never build marketing profiles from the details you share with us.
Where applicable data protection law requires a legal basis for processing personal information, we rely on one or more of the following grounds. Our processing is carried out only to the extent necessary and in a manner consistent with the expectations of the individuals whose information we handle.
We rely on legitimate interests when we respond to enquiries, operate our website securely, and improve our services. We rely on the performance of a contract or the steps taken before entering a contract when we communicate with prospective clients about a potential engagement. We rely on consent in cases where we ask for it explicitly, and we rely on legal obligation when we must retain records or disclose information to comply with the law.
You may withdraw consent at any time where consent is the basis for processing. Withdrawal does not affect the lawfulness of processing carried out before the withdrawal. To withdraw consent or to object to processing, please contact us using the details in the final section of this policy.
We work with a limited number of third party service providers who help us operate our business, such as hosting providers, email providers, and analytics providers. These providers process information only on our instructions and under contractual obligations that require them to protect the confidentiality and security of the data they handle.
We do not sell your personal information, and we do not share it with third parties for their own independent marketing. Information is disclosed to service providers only to the extent required to perform the functions we have engaged them to perform, and those providers are not permitted to use the information for any other purpose.
In certain circumstances we may disclose information where disclosure is required by law, by a court order, or by a governmental authority with a lawful right to request it. We may also disclose information to protect the rights, property, or safety of our organization, our clients, or the public, in accordance with applicable law.
We retain personal information only for as long as is necessary to fulfill the purposes described in this policy, unless a longer retention period is required or permitted by law. The precise retention period depends on the nature of the information and the purpose for which it was collected.
Enquiry correspondence is typically retained for a reasonable period so that we can respond to follow up questions and maintain accurate business records. Technical logs used for security and analytics are retained on a shorter cycle and are periodically deleted or anonymized. When information is no longer needed, we delete it or render it unreadable.
Where a legal, accounting, or regulatory obligation requires us to keep certain records, we retain those records for the period required by the relevant obligation and no longer. We review our retention practices regularly to ensure that personal information is not kept longer than necessary.
We take the security of personal information seriously and apply appropriate technical and organizational measures to protect it against unauthorized access, alteration, disclosure, or destruction. These measures are proportionate to the sensitivity of the information and to the risks associated with its processing.
Our security practices include access controls, encryption in transit, and regular review of our systems and processes. Access to personal information is limited to personnel who require it to perform their duties, and those personnel are bound by obligations of confidentiality.
No method of transmission over the internet or of electronic storage is completely secure, and we cannot guarantee absolute security. If you have reason to believe that your interaction with us is no longer secure, please notify us immediately using the contact details provided at the end of this policy.
Depending on your location and the law that applies to you, you may have certain rights regarding your personal information. These rights may include the right to access, the right to correct, the right to delete, the right to restrict processing, and the right to data portability.
You may also have the right to object to certain processing activities and the right to withdraw consent where we rely on consent. If you wish to exercise any of these rights, please contact us using the details provided in this policy, and we will respond within the timeframes required by applicable law.
We will verify your identity before acting on a rights request to ensure that personal information is only disclosed to the person entitled to receive it. If you believe we have not handled your request appropriately, you may also have the right to lodge a complaint with the relevant supervisory authority in your jurisdiction.
If you are located in the European Economic Area, the United Kingdom, or another jurisdiction with comparable laws, you may have additional rights under the General Data Protection Regulation or its equivalents. We will honor those rights to the extent they apply to the processing we carry out, and we will not discriminate against you for exercising any right available to you.
Quanwen Technology Limited is based in Hong Kong (HK), and the information we collect may be processed in Hong Kong or in other jurisdictions where our service providers operate. Where personal information is transferred across borders, we take steps to ensure that it continues to receive an appropriate level of protection.
We rely on safeguards recognized by applicable law, such as standard contractual clauses or equivalent mechanisms, when transferring information to countries that have not been found to provide an adequate level of protection. Our service providers are required to maintain safeguards consistent with this policy.
By using this website and providing information to us, you acknowledge that your information may be transferred to and processed in jurisdictions outside your country of residence, including jurisdictions that may have different data protection rules.
This website is intended for business users and for adults who are interested in computer systems design and related services. It is not directed to children, and we do not knowingly collect personal information from children under the age of sixteen.
If you are a parent or guardian and believe that a child in your care has provided personal information to us, please contact us immediately using the details in this policy. We will take reasonable steps to verify the situation and to delete the information from our records as required by applicable law.
We do not use the website to market to minors, and we do not offer services to individuals who cannot lawfully enter into a contract for our professional services.
We may update this Privacy Policy from time to time to reflect changes in our practices, our services, or applicable law. When we make changes, we will revise the last updated date shown at the top of this page, and the revised policy will take effect when it is published.
Where changes are material, we will make a reasonable effort to bring them to your attention by a prominent notice on this website. We encourage you to review this policy periodically so that you remain informed about how we protect your information.
Your continued use of the website after changes to this policy take effect constitutes your acceptance of the revised policy. If you do not agree with the changes, you should stop using the website and contact us with any concerns.
If you have any questions, concerns, or requests regarding this Privacy Policy or the way we handle personal information, please contact us using the details below. We are committed to responding to privacy enquiries promptly and in good faith.
