No Automated Decision-Making and Profiling. As part of the Website, we do not engage in automated decision-making and/or profiling, which produces legal or similarly significant effects.

Your rights

General. European data protection laws give you certain rights regarding your personal information. If you are located in Europe, you may ask us to take the following actions in relation to your personal information that we hold:

  • Access. Provide you with information about our processing of your personal information and give you access to your personal information.
  • Correct. Update or correct inaccuracies in your personal information.
  • Delete. Delete your personal information where there is no lawful reason for us continuing to store or process it, where you have successfully exercised your right to object to processing (see below), where we may have processed your information unlawfully or where we are required to erase your personal information to comply with local law. Note, however, that we may not always be able to comply with your request of erasure for specific legal reasons that will be described to you, if applicable, at the time of your request.
  • Portability. Port a machine-readable copy of your personal information to you or a third party of your choice, in certain circumstances. Note that this right only applies to automated information for which you initially provided consent for us to use or where we used the information to perform a contract with you.
  • Restrict. Restrict the processing of your personal information, if, (i) you want us to establish the personal information’s accuracy; (ii) where our use of the personal information is unlawful but you do not want us to erase it; (iii) where you need us to hold the personal information even if we no longer require it as you need it to establish, exercise or defend legal claims; or (iv) you have objected to our use of your personal information but we need to verify whether we have overriding legitimate grounds to use it.
  • Object. Object to our processing of your personal information where we are relying on Legitimate Interests (or those of a third party) and there is something about your particular situation that makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedom – you also have the right to object where we are processing your personal information for direct marketing purposes.
  • Withdraw Consent. When we use your personal information based on your consent, you have the right to withdraw that consent at any time. This will not affect the lawfulness of any processing carried out before you withdraw your consent.

Exercising These Rights. You may submit these requests by email to [email protected] or our postal address provided above. We may request specific information from you to help us confirm your identity and process your request. Whether or not we are required to fulfill any request you make will depend on a number of factors (e.g., why and how we are processing your personal information), if we reject any request you may make (whether in whole or in part) we will let you know our grounds for doing so at the time, subject to any legal restrictions.

Your Right to Lodge a Complaint with your Supervisory Authority. In addition to your rights outlined above, if you are not satisfied with our response to a request you make, or how we process your personal information, you can make a complaint to the data protection regulator in your habitual place of residence.

Data Processing outside Europe

We are an Australia-based company with operations in the United States and many of our service providers, advisers, partners or other recipients of data are also based in Australia. This means that, if you use the Website, your personal information will necessarily be accessed and processed in Australia. It may also be provided to recipients in other countries outside Europe.

It is important to note that that Australia is not the subject of an ‘adequacy decision’ under the GDPR – basically, this means that the Australian legal regime is not considered by relevant European bodies to provide an adequate level of protection for personal information, which is equivalent to that provided by relevant European laws.

Where we share your personal information with third parties who are based outside Europe, we try to ensure a similar degree of protection is afforded to it by making sure one of the following mechanisms is implemented:

  • Transfers to territories with an adequacy decision. We may transfer your personal information to countries or territories whose laws have been deemed to provide an adequate level of protection for personal information by the European Commission or UK Government (as and where applicable) (from time to time).
  • Transfers to territories without an adequacy decision.
    • We may transfer your personal information to countries or territories whose laws have not been deemed to provide such an adequate level of protection (e.g., Australia, see above).
    • However, in these cases:
      • we may use specific appropriate safeguards, which are designed to give personal information effectively the same protection it has in Europe – for example, standard-form contracts approved by relevant authorise for this purpose; or
      • in limited circumstances, we may rely on an exception, or ‘derogation’, which permits us to transfer your personal information to such country despite the absence of an ‘adequacy decision’ or ‘appropriate safeguards’ – for example, reliance on your explicit consent to that transfer.

You may contact us if you want further information on the specific mechanism used by us when transferring your personal information out of Europe. You may have the right to receive a copy of the appropriate safeguards under which your personal information is transferred by contacting us at [email protected].
