1. Introduction

This Privacy Policy describes how drhong.com.hk (“we,” “us,” or “our”) collects, uses, stores, and shares your personal data when you use our website. By accessing or using our site, you acknowledge that you have read this policy and understand our practices regarding the collection and use of information in accordance with its terms.

We are committed to protecting your privacy and ensuring that your personal data is handled in compliance with applicable data protection laws, including the Personal Data (Privacy) Ordinance (Cap. 486) of the Laws of Hong Kong.

2. Information We Collect

We collect information to provide and improve our services. This includes:

  • Personal Data: Information you provide directly to us, such as your name, email address, and communication content when you submit inquiries via our contact forms.
  • Transaction Data: When you make a purchase, payment information is collected. Please note that we do not store full credit card numbers or sensitive payment details on our servers; this is handled securely by our payment processor, Stripe.
  • Usage Data: Technical information about how you access and interact with our site, including your IP address, browser type, regional preferences, and activity logs related to the access and download of purchased digital files.

3. Purposes of Data Collection and Processing

In accordance with the Data Protection Principles of the PDPO, we collect and process your personal data for the following specific purposes:

  • Service Fulfilment: To process payments securely via Stripe and to validate and deliver your purchased digital or physical content.
  • Communication: To respond to inquiries you voluntarily submit through our contact forms.
  • Operational Integrity: To maintain website security, prevent fraud, and analyze the performance of our book availability links.

4. Cookie Usage and Third-Party Service Providers

We use cookies and similar technologies provided by trusted third-party service providers to ensure core website functionality and provide regional routing.

A. Core Website Functionality (First-Party Cookies)

We use internal cookies essential for the proper functioning of the website, specifically for the delivery of digital goods. These cookies allow us to authenticate your session after a successful purchase, validate your permission to access the download link, and manage the security of the file transfer.

Duration: Session duration (deleted when the browser is closed or the download expires).

B. Stripe (Payment Processing)

When you make a direct purchase, Stripe sets cookies to process payments securely and detect/prevent fraudulent transactions.

Duration: Session duration for transactions; up to 90 days for fraud prevention.

C. FormSubmit (Contact Form Processing)

When you submit the contact form on this website, your name, email address, selected subject, and message are transmitted to and processed by FormSubmit.co, a third-party form-handling service. FormSubmit.co delivers your submission to us by email and does not store your data on its servers beyond what is necessary to complete delivery.

We use the email address you provide solely to respond to your inquiry and, where you have explicitly opted in, to send you updates about Systems Chiropractic and drhong.com.hk. Your email address is never sold, rented, or shared with any third party for marketing purposes. To reduce the risk of typographical errors and protect against abuse, the contact form requires you to confirm your email address. This website also uses FormSubmit.co's built-in spam-detection mechanisms, including honeypot fields, to discard automated bot submissions silently.

D. Booklinker (Link Management)

When you click our book availability links, Booklinker uses cookies to determine your geographic location and redirect you to the correct regional Amazon storefront.

Duration: Up to 12 months.

E. Amazon (Book Information)

When you are redirected to Amazon via our links, Amazon may set cookies to display real-time pricing and maintain your shopping session on their platform. Once you leave our site for Amazon, your data is governed by Amazon’s Privacy Notice.

Duration: Up to 365 days.

F. MyWOT (Website Trust & Reputation Badge)

This website displays a trust badge provided by MyWOT Services Oy (mywot.com). To render this badge, a script is loaded from MyWOT's servers when you visit a page displaying it. This script may collect technical information such as your IP address and browser type as part of standard web request logging. We do not receive or control this data.

5. Managing Cookies

  • Strictly Necessary Cookies: The cookies listed in Sections 4A and 4B are classified as “Strictly Necessary” for the operation of the site (e.g., completing a payment or securing a digital download). While you can configure your browser to block these cookies, doing so will prevent the website from functioning correctly.
  • Functional and Third-Party Cookies: The cookies and scripts utilized by Booklinker, Amazon, and MyWOT (Sections 4D, 4E, and 4F) are functional and third-party tracking technologies. These operate when you interact with specific outbound links or trust badges. You may manage or block these through your browser settings, though doing so may affect geographic routing for book purchases.
  • Local Storage Usage: This website uses your browser's localStorage to store a single timestamp when a site-update notice is displayed to you, solely to suppress the notice for seven (7) days. No personal data is stored in localStorage, and this information never leaves your device. You may clear this data at any time through your browser's settings.

6. Data Retention

We retain your personal data only for as long as necessary to fulfill the purposes for which it was collected, including for the purposes of satisfying any legal, accounting, or reporting requirements.

  • Contact Form Data: Retained only as long as necessary to resolve your inquiry, and generally deleted within 90 days thereafter.
  • Transaction Records: Retained as required by applicable tax and accounting laws.

7. Information Sharing and Cross-Border Transfers

We do not sell, rent, or trade your personal information to third parties. We share your personal data only with trusted third-party service providers to facilitate our services:

  • Fulfilment of Physical Goods: If you purchase a physical item, we transfer necessary shipping details (name, address, phone number, email) to fulfilment partners (e.g., Amazon Fulfilment Services) solely to process and ship your order.
  • Essential Service Providers: We share data with Stripe (payment processing) and FormSubmit (inquiry delivery) to maintain business operations.
  • Cross-Border Transfers: As we utilize international service providers (such as Stripe, FormSubmit, Booklinker, Amazon, and MyWOT), your data may be transferred to, and processed in, jurisdictions outside of Hong Kong. We ensure these processors are engaged under appropriate data protection arrangements.
  • Legal Requirements: We may disclose your information if required to do so by law or in response to valid requests by public authorities.

8. Your Data Rights

Depending on your jurisdiction, you may have specific rights regarding your personal data, which may include the right to erasure or withdrawal of consent where applicable by law.

Your Rights Under the PDPO

Under the Personal Data (Privacy) Ordinance (Cap. 486), you have the right to request access to, and correction of, your personal data. Please note that we practice strict data minimization. Correspondence received via our contact form or email is routinely deleted once the inquiry is resolved, meaning we generally do not retain searchable profiles or communication histories.

Furthermore, all payment and transaction data is processed and securely maintained by our third-party payment processor, Stripe, and is subject to their respective privacy and retention policies.

For any inquiries regarding the limited data we may temporarily hold, you may contact us via email. We will respond to formal requests within forty (40) days in accordance with the Ordinance. A reasonable fee may be charged for processing a data access request as permitted under the PDPO.

To exercise these rights, please contact us at: info@drhong.com.hk

Our website contains links to external sites, specifically Amazon, as well as third-party social media platforms including LinkedIn, Facebook, and X (formerly Twitter). Please be aware that we are not responsible for the content or privacy practices of such other sites. Clicking these links will take you to external websites governed by their own privacy policies. We have no control over, and accept no responsibility for, the privacy practices or content of those platforms. We encourage our users to be aware when they leave our site and to read the privacy statements of any other site that collects personally identifiable information.

10. Governing Law

This Privacy Policy and any disputes related thereto shall be governed by and construed in accordance with the laws of the Hong Kong Special Administrative Region.
