2. What we collect

Depending on how you use the Site, we may collect:

• Account data — name, email address and preferences when you register or subscribe.
• Usage data — pages viewed, features used, device and browser information, and approximate location from your IP address.
• Communications — messages you send us, support tickets and feedback.
• Cookies — see our Cookie Policy.

We do not knowingly collect sensitive personal data (health, religion, political opinions, sexual orientation, biometric data or precise geolocation), and we do not knowingly collect data from children under 18.

3. How we use it

• provide and operate the Service;
• manage your account and subscriptions;
• process payments;
• respond to your queries and provide support;
• send transactional service messages, and marketing messages only where you have opted in (always with an unsubscribe option);
• analyse aggregated usage to improve the Service;
• comply with the law and enforce our agreements.

4. Legal basis

Where the GDPR, UK GDPR or an equivalent law applies, we rely on: performance of a contract; legitimate interests; legal obligation; and consent (for marketing). If you object to legitimate-interest processing, contact us.

Under the Personal Data (Privacy) Ordinance (Cap. 486) of Hong Kong, we collect and use personal data only for a purpose directly related to our function, and we give you the rights described below.

5. Who we share it with

• service providers that help us operate the Site (hosting, analytics, email delivery and payment processing) — see our Sub-processors page;
• professional advisers;
• authorities, where required by law.

We do not sell your personal data to advertisers.

6. International transfers

We are based in Hong Kong. Our service providers may be located elsewhere. Where a transfer requires a safeguard, we use the European Commission's Standard Contractual Clauses and, for UK transfers, the UK ICO's International Data Transfer Addendum.

7. Retention

We keep personal data only as long as needed: account and billing data for the life of the account and for applicable tax and legal periods (typically seven years in Hong Kong); usage logs for up to 13 months; support communications for up to three years.

8. Your rights

Depending on where you live, you may have the right to access, correct, delete or restrict your data, to object to processing, and to data portability. To exercise any right, contact helen.ha@kfchow.com or use our Data Removal page. We respond within the time required by applicable law (30 days under the GDPR). You may complain to the Office of the Privacy Commissioner for Personal Data (PCPD) in Hong Kong, or to your local supervisory authority.
