Sharing of information

We limit the sharing of personal information to what is necessary for business operations, legal compliance or the functioning of this website. Information may be shared with service providers who assist with hosting, technical support, form handling, data storage or related administrative functions, subject to appropriate confidentiality and security measures.

We may also disclose information where required to do so by law, court order, lawful request from a public authority or to protect rights, property or safety. If information needs to be processed outside South Africa, we will take reasonable steps to ensure that appropriate protection is in place and that the transfer is lawful under POPIA.

Storage, security and retention

We take reasonable technical and organisational steps to protect personal information against loss, misuse, unauthorised access, disclosure, alteration or destruction. No internet transmission or electronic storage method can be guaranteed completely secure, but we apply safeguards appropriate to the nature of the information processed through this website.

Access controls for authorised personnel only
Use of secure systems and routine maintenance measures
Administrative controls over how enquiries are handled
Retention of records only for as long as reasonably required or as required by law

When personal information is no longer needed for the purpose for which it was collected, we will delete, destroy or de-identify it where reasonably practicable, unless retention is required by law or for legitimate business record-keeping.

Your rights under POPIA

Subject to POPIA and any other applicable law, you may have the right to ask what personal information we hold about you, request correction of inaccurate information, object to certain processing, or request deletion where there is no lawful basis to retain the information.

If you wish to exercise any of these rights, please use the enquiry form on our contact page and clearly state your request. We may need to verify your identity before acting on the request. If you believe your information has been handled unlawfully, you may also lodge a complaint with the relevant South African information regulator.
