General security measures

This includes:
  • Encryption of your personal data in transit and in rest;
  • Systematic vulnerability scanning and penetration testing;
  • Protection of data integrity;
  • organizational and legal measures: For example, our employees have different levels of access to your personal data and only access your personal data for limited and necessary purposes required for the operation of the Services. We impose strict responsibility on our employees for any disclosure, unauthorized access, alteration, destruction, or misuse of your personal data; and
  • Conducting periodical Data Protection Impact Assessments (DPIA) in order to ensure that the Services fully adhere to the principles of privacy by design, privacy by default, and others. We also commit to undertake a privacy audit in the event of Centenum Health's merger or takeover.

No security system is perfect. Therefore, we cannot guarantee the absolute security of the Services or that your information will not be intercepted while being transmitted to us.

Security breaches If we learn of a security systems breach, we may either post a notice or attempt to notify you by email and will take reasonable steps to remedy the breach as specified in applicable law and this Privacy Policy.
