1. What are cookies?
Cookies are small text files stored on your device (computer, phone, tablet) when you visit a website. Cookies help websites function properly, remember preferences, enhance security, and provide insights about usage. We may also use similar technologies (for example, local storage, pixels, SDKs) that function like cookies.
2. How we use cookies
We use cookies and similar technologies for the following purposes:
* To operate our website and services (core functionality).
* To maintain security, prevent fraud, and protect our infrastructure.
* To remember your preferences and improve user experience.
* To understand website performance and usage (analytics), where enabled.
* To support marketing/advertising activities, where enabled and permitted by law.
3. Legal basis and compliance
We process personal data in connection with cookies in accordance with the Hong Kong Personal Data (Privacy) Ordinance (PDPO) and, where applicable (for example, if GDPR applies to our processing), GDPR requirements.
Strictly necessary cookies are used based on our legitimate interests in operating a secure and functional service and/or as required to provide the services you request.
For non-essential cookies (such as analytics and marketing cookies), we request your consent where required by applicable law.
For details on how we process personal data, please see our Privacy Policy: [PRIVACY_POLICY_URL].
4. Consent categories
We categorize cookies and similar technologies as follows:
4.1 Strictly Necessary (Always Active)
These cookies are required for the website and services to function properly, including security, authentication, session management, load balancing, and other essential operations. They cannot be disabled in our systems.
4.2 Functional (Optional)
These cookies enable enhanced functionality and personalization, such as remembering your language, region, or interface settings. If you disable these cookies, some features may not work correctly.

These cookies may be used to deliver relevant advertising, measure ad performance, and build audiences based on your activity. We use marketing cookies only where enabled and where legally permitted, and where required, with your consent.
4.5 Security / Anti-Abuse (Necessary or Optional depending on context)
Some security-related technologies are necessary to protect our website and users (for example, bot detection, abuse prevention, and fraud mitigation). Where a security cookie is not strictly necessary under applicable law, we will treat it as optional and request consent accordingly.
