Data protection

1. Local data protection laws and scope

3. Anticipated changes to local laws

The legislation is due for amendment since its last substantive amendment in 2012.

The Constitutional and Mainland Affairs Bureau released LC Paper.

  • Provision of Sanctioning Powers to PCPD to impose administrative fines and raise relevant criminal fine levels; 
  • Regulation of Data Processors; 
  • Amending the Definition of Personal Data to cover information relating to an "identifiable" natural person; 
  • Regulation of Disclosure of Personal Data of Other Data Subjects to curb doxing;

5. Registration / notification / authorisation

There is no requirement for notification/registration/authorisation for processing personal data (i.e. no mechanism similar to that in UK Notification to process personal data - GOV.UK (

6. Main obligations and processing requirements

Data users shall comply with the six principles set out in Schedule 1 to the Ordinance: 

  • personal data shall only be collected for a lawful purpose directly related to a function or activity of the data user. The data collected should be necessary and adequate but not excessive for such purpose. The means of collection should be lawful and fair; 
  • data users are required to take all practicable steps to ensure that personal data is accurate and not kept longer than is necessary for the fulfilment of the purpose for which the data is used. If data users engage a data processor for handling personal data of other persons, data users should adopt contractual or other means to ensure that the data processor comply with the mentioned retention requirement; 
  • data users shall not use personal data for any new purpose which is not or is unrelated to the original purpose when collecting the data, unless with the data subject’s express and voluntary consent; 
  • data users shall take all practicable steps to protect the personal data they hold against unauthorised or accidental access, processing, erasure, loss or use; 
  • data users are required to take all practicable steps to ensure openness of their personal data policies and practices, the kind of personal data held and the main purposes for holding it; and 
  • data users shall provide data subjects with the right to request access to and correction of their own personal data.

7. Data subject rights

Data subjects are given the right to access and make correction to their data.

8. Processing by third parties

No direct regulation on data processors.  However, data are required to adopt contractual means to ensure that data processors or sub-contractors adopt measures to ensure the safety of personal data.

9. Transfers out of country

A data user shall not transfer personal data outside Hong Kong unless one of the following conditions is met: 

  • the place is specified by the Commissioner by notice in the Gazette that there is in force any law which is substantially similar to, or serves the same purposes as, the Ordinance – no place has satisfied this condition up to date. 
  • The data user has reasonable grounds for believing that there is in force in that place any law which is substantially similar to, or serves the same purposes as, the Ordinance;
  • The data subject has consented in writing to the transfer;
  • The data user has reasonable grounds for believing that the transfer is for the avoidance or mitigation of adverse action against the data subject; it is not practicable to obtain the consent in writing of the data subject to that transfer; but if it was practicable, such consent would be given;
  • The data is exempt from Data Protection Principle 3 by virtue of an exemption under Part VIII of the Ordinance (such as personal data held for news activities, for domestic use, for purpose of prevention of crime etc.); or
  • The data user has taken all reasonable precautions and exercised all due diligence to ensure that the data will not, in that place, be collected, held, processed, or used in any manner which, if that place were Hong Kong, would be a contravention of a requirement under the Ordinance. Please note that use of recommended model data transfer clauses to develop an enforceable data transfer contract by data users is one method to satisfy the required due diligence requirement. 

10. Data Protection Officer


11. Security

There is no mandatory requirement.  However, it is required that a data subject is informed of the name or job title, and address, of the individual who is to handle the data access or correction request made to the data user.

12. Breach notification

There is no mandatory requirement, but a data breach may amount to a contravention of 

  • Data Protection Principle 4(1); and in Schedule 1 of the Ordinance;

The following action plan is recommended as practice to be adopted by data users: 

  • immediate gathering of essential information relating to the breach; 
  • contacting the interested parties and adopting measures to contain the breach; 
  • assessing the risk of harm; 
  • considering the giving of data breach notification: notifying the affected data subjects, the relevant parties, the law enforcement agencies, the Commissioner, relevant regulators and such other parties who may be able to take remedial actions as soon as practicable after the defection of the data breach.  For notifying the Commissioner, a “Data Breach Notification Form” can be used.

13. Direct marketing

The data user must:

  • inform the data subject (i) that the data user intends to so use the personal data; and (ii) that the data user may not so use the data unless the data user has received the data subject’s consent to the intended use – this “consent” needs to be “an indication of no objection to the use or provision” and hence, silence or lack of response will not be deemed to be consent;
  • provide the data subject with the following information in relation to the intended use (i) the kinds of personal data to be used; and (ii) the classes of marketing subjects in relation to which the data is to be used –  the description of such classes should be specific, making reference to the distinctive features of the goods, facilities or services so that it is practicable for the customers to ascertain the goods, facilities or services to be marketed with a reasonable degree of certainty; and
  • provide the data subject with a channel through which the data subject may, without charge by the data user, communicate the data subject’s consent to the intended use – a data user can only elect a response channel that enables the data subject’s consent to be made in writing.

14. Cookies and adtech

There are no specific requirements in relation to use of cookies.  

However, the use of cookies to collect personal data needs to be in compliance with Data Protection Principle 1(3) in Schedule 1 to the Ordinance that requires: 

  • the data subject is explicitly or implicitly informed, on or before collecting the data, of (i) whether it is obligatory or voluntary for him or her to supply the data; and (ii) where it is obligatory for him or her to supply the data, the consequences for him or her if he or she fails to supply the data; and 
  • he or she is explicitly informed: (i) on or before collecting the data, of (A) the purpose (in general or specific terms) for which the data is to be used; and (B) the classes of persons to whom the data may be transferred; and (ii) on or before first use of the data for the purpose for which it was collected, of (A) his or her rights to request access to and to request the correction of the data; and (B) the name or job title, and address, of the individual who is to handle any such request made to the data user.
