Deer Network Systems Limited (“Deer Network”, “we”, “us” or “our”) respects your privacy. This Privacy Policy explains how we collect, use, disclose and protect personal data when you visit deer.hk, contact us, or deal with us in connection with our IT, networking and telecommunications solutions.
We handle personal data in accordance with the Personal Data (Privacy) Ordinance (Cap. 486) of Hong Kong (“PDPO”) and its Data Protection Principles (“DPPs”), and other applicable laws. This Policy is written for a Hong Kong B2B IT services context. We do not claim to appoint an EU GDPR representative, and nothing here creates rights that do not apply under Hong Kong law.
1. Data user identity (who we are)
The data user responsible for personal data collected through our websites and business enquiries is:
Deer Network Systems Limited
For our current office address and telephone numbers, please see Contact Us.
2. Personal data we collect
Depending on how you interact with us, we may collect:
- Identity and contact details — name, company, job title, email address, telephone number
- Enquiry and project information — messages and attachments you submit via website contact forms, email, telephone or live chat (including 3CX Live Chat where enabled)
- Technical and usage data — IP address, browser type, device information, referring pages and pages visited (via server logs and, if enabled, analytics)
- Cookie and similar technology data — as described in the Cookies section below and controlled via our CookieYes consent banner
We collect personal data mainly from you directly. We do not seek sensitive categories of personal data for website browsing alone. Please do not submit unnecessary personal data about third parties without a lawful basis to do so.
3. Purposes of collection and use (PDPO DPP1 & DPP3)
Under DPP1 (purpose and collection) and DPP3 (use of personal data), we collect personal data for purposes that are directly related to our functions, and we use it only for those purposes or a directly related purpose, unless you consent otherwise or the law permits or requires another use.
We use personal data to:
- Respond to enquiries, arrange discussions and provide quotations or proposals
- Deliver, manage and support IT, networking, cybersecurity, telecommunications and related professional services under written contracts
- Operate, secure, troubleshoot and improve our websites and communications systems (including forms, email and live chat)
- Comply with legal, regulatory, audit and contractual obligations
- Send service-related messages; and, where permitted, limited business marketing — you may opt out at any time by contacting us
Where we rely on a practical basis for processing (for clarity alongside the PDPO), that typically includes: your consent (for example non-essential cookies via CookieYes, or optional marketing); steps prior to or performance of a contract (for example responding to a request for quotation); and legitimate business interests that are not overridden by your rights (for example website security, fraud prevention and B2B relationship management), always subject to the PDPO.
4. Accuracy (PDPO DPP2)
Under DPP2, we take practicable steps to ensure that personal data we hold is accurate having regard to the purposes for which it is used. Please help us keep your details current by telling us of changes. If you believe data we hold is inaccurate, you may request correction as described in the Access and correction section below.
5. Retention (PDPO DPP2)
Also under DPP2, we do not keep personal data longer than is necessary for the purposes for which it is used. Retention periods depend on the nature of the record — for example enquiry correspondence may be kept for a shorter operational period, while contractual, billing or compliance records may be retained for longer as required by law or legitimate business need. When data is no longer needed, we take practicable steps to erase or anonymise it.
6. Security (PDPO DPP4)
Under DPP4, we take practicable steps to protect personal data against unauthorised or accidental access, processing, erasure, loss or use. Measures may include access controls, secure hosting arrangements, staff awareness and contractual safeguards with service providers. No method of transmission over the Internet or electronic storage is completely secure; we cannot guarantee absolute security.
7. Openness; access and correction (PDPO DPP5 & DPP6)
Under DPP5 (openness), this Privacy Policy sets out our personal data policies and practices in general terms, including the kinds of data we hold and the main purposes of use.
Under DPP6 (access and correction), you may request access to personal data we hold about you, and request correction of inaccurate personal data. To make a data access request or data correction request:
- Email [email protected] with the subject line “PDPO data access request” or “PDPO data correction request”
- Provide enough information for us to verify your identity and locate the relevant data
- For correction requests, state clearly what should be corrected and why
We will respond within the timeframes required by the PDPO. Where permitted by law, we may charge a reasonable fee for complying with a data access request. We may refuse a request only on grounds allowed under the PDPO (for example where the request is not made in writing as required, or where exemptions apply); if we refuse, we will explain the reason where practicable.
For independent guidance on your rights under the PDPO, you may consult the Office of the Privacy Commissioner for Personal Data, Hong Kong (“PCPD”) at www.pcpd.org.hk.
8. Cookies and similar technologies
Our websites may use cookies or similar technologies that are:
- Strictly necessary — required for the site to function (for example security, load balancing or remembering consent choices)
- Preferences — such as light/dark theme where offered
- Analytics — to understand aggregate traffic and improve the site (only if enabled and, where required, after consent)
- Functional / chat — for example live chat session cookies when 3CX Live Chat is active
We use the CookieYes (Cookie Law Info) consent banner so you can accept, reject or manage non-essential cookies where that choice is offered. You can reopen cookie preferences via the CookieYes interface on the site (typically a floating button or footer control after your first visit). You may also control cookies through your browser settings; disabling some cookies may affect site features.
Cookie-related personal data is used only for the purposes described above and in line with DPP1 and DPP3. For further detail on categories shown in the banner, use “Manage cookies” / CookieYes preferences on the site.
9. Disclosure to third parties
We may share personal data with:
- Authorised staff and group personnel who need it to serve you
- Trusted service providers acting on our instructions — for example website hosting, email delivery, form handling, live chat (such as 3CX), cookie consent tooling (CookieYes) and, if enabled, analytics — under appropriate confidentiality and data-protection arrangements
- Professional advisers, insurers, or competent authorities where required by law or to protect our rights, property or safety
We do not sell your personal data. We do not disclose personal data for a new purpose unrelated to the original collection without your consent or another basis allowed under the PDPO.
10. Transfers outside Hong Kong
Some service providers or systems may process data outside Hong Kong (for example cloud hosting, email or chat infrastructure in other jurisdictions). Where personal data is transferred outside Hong Kong, we take practicable steps consistent with the PDPO to protect it, including contractual and operational safeguards appropriate to the transfer.
11. Children’s data
Our websites and services are directed at businesses and professionals. We do not knowingly collect personal data from children under 16. If you believe a child has provided personal data to us, please contact [email protected] so we can take appropriate steps to delete it.
12. Third-party sites and embedded tools
Our site may link to third-party websites or embed tools (for example partner sites or live chat). Their privacy practices are their own. Please review their policies separately before providing personal data to them.
13. Changes to this Policy
We may update this Privacy Policy from time to time. The “Last updated” date at the top will change when we do. The current version will be posted on this page. Continued use of our websites after an update means you acknowledge the revised policy.
