HHG strives to carry out its business activities in accordance with the principles of privacy, as we believe that they are an indication of our unwavering commitment to ethical and responsible practices. We recognise that innovation and new technologies lead to constant changes as regards risks, expectations, and legislation, and that is why we follow the standards of undertaking responsibility for privacy, and also why we aim to adapt their implementation in response to these changes in a timely manner.

This Policy is also in force for all individuals whose data we process, including, but not limited to, customers, potential and former employees and their dependants, members of the morals and ethics committee, partners, investors and shareholders, state employees, and other stakeholders.

All Group Employees and Management Executives bear significant responsibilities as regards the protection of privacy, which they must observe.

All Group employees and other individuals who process data for our companies, are responsible for understanding and observing their obligations with regard to this Policy and current laws.

Our Values and Standards with regard to Privacy

We observe our values regarding privacy in everything we do that has to do with people, including how we apply privacy standards. The four privacy values include:

  1. Respect - We recognise that concerns about privacy are often related to the essential questions of who we are, how we see the world, and how we define ourselves. Thus, we strive to respect the perspective and interests of individuals and societies, and to be fair and transparent in how we use and share data regarding them.
  2. Trust - We know that trust is of vital importance for our success, and that is why we strive to create and keep the trust of our customers, employees, patients, and other stakeholders, with regard to respect and protection of data related to them.
  3. Avoiding damage - We understand that misuse of data related to people may cause tangible and intangible damage to those people, and thus we strive to deter physical and financial damage, damage to their reputation or any other type of damage related to privacy.
  4. Compliance - We have learned that laws and regulations do not always keep up with the rapid developments of technology, the flow of data, and related changes in the risks and expectations of privacy. Thus, we strive to comply with the spirit and the regulations of privacy, as well as the laws of data protection, in a way that is consistent and operationally sound for our business activities on a global level.

We incorporate privacy standards in all our activities, processes, technologies, and relationships with third parties that use Personal Data.

  2. Fairness – We do not process Personal Data in ways that are unfair to the people whom those data relate.
  3. Transparency – We do not process Personal Data in ways or for purposes that are not transparent.
  4. Purpose Limitation – We only use Personal Data in accordance with the principles of Necessity and Transparency.
  5. Data Quality – We keep Personal Data accurate, complete, and up to date, and consistent with their intended use.
  6. Security – We implement safeguards to protect Personal Data and Sensitive Data from loss, misuse, and unauthorised access, disclosure, or destruction.
