In addition, in some jurisdictions, data protection law requires that the processing of your personal data for some or all of the purposes described above (including the provision of direct marketing to you) must be on the basis of your consent and, therefore, where consent is necessary, our processing of your personal data is on the basis of your consent.

Please note that where your consent is required to process your personal data, you are entitled to refuse to give your consent or revoke it any time. However, by not providing your consent (or revoking it), we may not be able to provide the relevant services to you.

Direct marketing

Our range of products, services and solutions is constantly evolving to match the increasingly sophisticated markets in which we operate. Therefore, we may wish to provide you with information about similar or the same products, services, solutions, promotions and offers, to those about which you receive or have enquired about and which may be of interest to you. We may also invite you to take part in market research or request feedback on our products, services and solutions. Such communications may be via e-mail, telephone, post or SMS.

Please note that marketing communications are not the same as “information only” communications and that we may communicate with you about the products you have purchased, or the services or solutions you have requested, using contact details you have provided for this purpose without your express consent being required.

Protection of your personal data

We use the industry-standard security protocol Secure Sockets Layer (SSL) to encode more sensitive information, such as credit card numbers for online purchase transactions via the Website. We employ the latest 128-bit encryption technology in all areas of the Website, which require you to provide personal or account information. This means that the credit card information you send is encrypted by your computer, and then decrypted again on our side, which limits the risk of others from accessing your private information when in transfer. You can verify this by looking for a closed lock icon at the bottom of your web browser or looking for "https" at the beginning of the address of the web page.

While we use encryption to protect credit card numbers and similar transaction information, please be aware that no method of transmission over the Internet is 100% secure. Although we take reasonable security measures to protect your personal data when we receive it, you also need to ensure you take appropriate steps to protect your personal data.

We also seek to protect your personal data offline. Only employees who need the information to perform specific job (for example, billing or customer service) are granted access to relevant personal data.

Retention of your personal data

We will retain your personal data as long as necessary for the purposes set out when collecting your personal data or as required by relevant laws and regulations.

The criteria we use to determine data retention periods includes the following:

  • Retention in case of queries

We may retain your personal data for a reasonable period after you have enquired about products, services or solutions, in case of follow up queries from you.

  • Retention in accordance with legal and regulatory requirements

We will consider whether we need to retain your personal data after the period of retention in the case of queries (above) because of a legal or regulatory requirement. Some or all of these criteria may be relevant to retention of your personal data collected from you in connection with our products, services, solutions and/or your use of the Website.

  • Retention permitted under applicable law

We will continue to retain personal data where necessary to provide our services to you and the retention of such personal data if necessary for the purposes of pursuing our legitimate interests or where it is necessary for public interest purposes.

Access to your personal data

You have the right to request confirmation as to whether or not your personal data is processed by us and you have reasonable access to your personal data, in order for your personal data to be updated, modified, or, if legally possible, deleted. In order for us to respond to your request, we may require you to verify your identity. You also have the right to withdraw your consent to any processing for which you have previously given that consent.

You can update your email subscription preferences at any time.

Please be aware that we may reject requests that are unreasonably repetitive, require disproportionate technical effort (for example, developing a new system or fundamentally changing an existing practice), risk the privacy of others, or would be extremely impractical (for instance, requests concerning information residing on backup systems).
