Where consent is not obtained, we may collect, use and disclose personal data pursuant to an exception under the PDPA or other written law when the use is necessary.

In addition, we limit access to your personal data to those employees, agents, contractors and other third parties who have a business need to know. They will only process your personal data on our instructions and they are subject to a duty of confidentiality.

Nevertheless, no method of storage or transmission is 100% secure. Although we will do our best to protect your information, we cannot completely guarantee the security of any Personal Data we may have collected from or about you,

We have put in place procedures to deal with any suspected personal data breach and will notify you and any applicable regulator of a breach where we are legally required to do so.


We will only retain your personal data for as long as necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, accounting, or reporting requirements.

After this period, your personal data will be irreversibly destroyed in accordance to our company’s disposal policy.

Any personal data held by us for marketing and service update notifications will be kept by us until such time that you notify us that you no longer wish to receive this information.


  • Request access to your personal data (commonly known as a “data subject access request”). This enables you to receive a copy of the personal data we hold about you and to check that we are lawfully processing it.
  • Request correction of the personal data that we hold about you.This enables you to have any incomplete or inaccurate data we hold about you corrected, though we may need to verify the accuracy of the new data you provide to us.
  • We will respond to your access and correction request as soon as reasonably possible. Should we not be able to respond to your request within thirty (30) days after receiving your access request, we will inform you in writing within thirty (30) days of the time by which we will be able to respond to your request. Where we are legally permitted to do so, we may refuse your request. However, we shall generally inform you of the reasons why we are unable to do so (except where we are not required to do so under the PDPA).
  • Request erasure of your personal data.This enables you to ask us to delete or remove personal data where there is no good reason for us continuing to process it. You also have the right to ask us to delete or remove your personal data 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 data 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 which will be notified to you, if applicable, at the time of your request.
  • Object to processing of your personal data.This enables you to object where we are relying on a legitimate interest (or those of a third party) and there is something about your particular situation which makes you want to object to processing on this ground as you feel it impacts on your fundamental rights and freedoms. You also have the right to object where we are processing your personal data for direct marketing purposes. In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your rights and freedoms.
  • Request restriction of processing of your personal data.This enables you to ask us to suspend the processing of your personal data in the following scenarios: (a) if you want us to establish the data’s accuracy; (b) where our use of the data is unlawful but you do not want us to erase it; (c) where you need us to hold the data even if we no longer require it as you need it to establish, exercise or defend legal claims; or (d) you have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.
  • Request the transfer of your personal data to you or to a third party. We will provide to you, or a third party you have chosen, your personal data in a structured, commonly used, machine-readable format. Note that this right only applies to automated information which you initially provided consent for us to use or where we used the information to perform a contract with you.
  • Withdraw consent.This allows you to withdraw your consent at any time where we are relying on consent to process your personal data. However, this will not affect the lawfulness of any processing carried out before you withdraw your consent. If you withdraw your consent, we may not be able to provide certain products or services to you. We will advise you if this is the case at the time you withdraw your consent. Please note that withdrawing consent does not affect our right to continue to collect, use and disclose personal data where such collection, use and disclosure without consent is permitted or required under applicable laws.

If you wish to exercise any of these rights, you will need to contact us using the contact details above. In the case of exercising your right to access, you will also need to provide appropriate evidence of your identity.


You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive or excessive. Alternatively, we may refuse to comply with your request in these circumstances.


We may need to request specific information from you to help us confirm your identity and ensure your right to access your personal data (or to exercise any of your other rights). This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request to speed up our response.


We may make changes to this policy from time to time, to take into account changes to our standard practices and procedures or where necessary to comply with new laws and regulations. The latest version of this policy will always be available on our website and we encourage to review it regularly. Any material changes may also be notified to customers by other means (such as email).
