Last updated: 2026-11-06
Who this is for
This notice is for business professionals whose professional information may appear in the data we publish or licence through the Site.
Who is responsible
KFChow AI Lab acts as an independent data controller for the professional data we compile from public and professional sources. Our data protection contact is helen.ha@kfchow.com.
What we hold
For a typical business professional, the information we may hold includes: full name, professional email address, professional phone number, job title, employer name and website, professional social-media profile, city and country of work, publicly reported events attended, and publicly available biographical information.
We do not knowingly collect sensitive categories of personal data, and we do not collect information about your personal, non-professional life.
Where we get it
Company websites and corporate filings; official registries; professional networks (where these restrict automated collection, we obtain the information through licensed providers or manual research from publicly accessible pages); industry associations and directories; trade-show and conference lists; press releases and publications; and our own research.
We do not use hacking, credential theft, phishing or unauthorised access, and we do not bypass authentication or paywalls. Where we collect data by automated means, we honour technical access controls.
Why we hold it
To provide B2B data and research services that our customers use to identify, research and contact organisations and the professionals who work in them. Customers are contractually prohibited from using the data for consumer marketing, credit, employment, insurance or housing decisions, or for training competing AI models.
Legal basis
For data subjects in the EEA, UK and equivalent jurisdictions, we rely on legitimate interests (GDPR Art. 6(1)(f)), supported by a written Legitimate Interests Assessment. In other jurisdictions we rely on the equivalent basis (for example, under the Hong Kong PDPO, use for a purpose directly related to the purpose for which the data was collected).
Who we share it with
Our customers, under contractual restrictions; sub-processors listed on our Sub-processors page; professional advisers; and authorities where required by law. We do not sell personal data to advertisers.
International transfers
We are based in Hong Kong. Our infrastructure and sub-processors include providers located in other regions. 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.
How long we keep it
We keep professional data while it remains useful for our purpose, and we re-verify or remove it when it becomes stale. If you ask us to delete your data, we remove it and add the minimum identifiers needed to recognise you to a suppression list so that we do not re-ingest it.
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. 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 your local supervisory authority.
