If that is not the case of said country, we may use specific standard contractual terms approved for use by our national regulator which give the transferred personal data the same protection as it has locally.
10. Data security
10.1. We have appropriate security measures to prevent your personal data from being accidentally lost, used or accessed in an unauthorised way, altered, disclosed or made inaccessible. 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.
10.2. We have 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.
11. Data retention
11.1. We will only retain your personal data for as long as reasonably necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, regulatory, tax, accounting or reporting requirements. We may retain your personal data for a longer period in the event of a complaint or if we reasonably believe there is a prospect of litigation in respect to our relationship with you.
11.2. To determine the appropriate retention period for personal data, we consider the amount, nature and sensitivity of the personal data, the potential risk of harm from unauthorised use or disclosure of your personal data, the purposes for which we process your personal data and whether we can achieve those purposes through other means, and the applicable legal, regulatory, tax, accounting or other requirements.
11.3. Our default data retention position is that we keep basic information about our customers, suppliers, partners and employees for 6 years after they cease their relationship with us. However certain records are kept for shorter or longer periods as required by legislation or our legitimate business interests.

12.1. You have the right to:
12.1.1. Request access to your personal data (commonly known as a “subject access request”).
12.1.2. Request correction of the personal data that we hold about you.
12.1.3. Request erasure of your 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, where we may have processed your information unlawfully or where we are required to erase your personal data to comply with local law. 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.
12.1.4. Object to processing of your personal data where we are relying on a legitimate interest (or those of a third party) as the legal basis for that particular use of your data (including carrying out profiling based on our legitimate interests). In some cases, we may demonstrate that we have compelling legitimate grounds to process your information which override your right to object.
12.1.5. Object any time to the processing of your personal data for direct marketing purposes.
12.1.6. Withdraw consent at any time where we are relying on consent to process your personal data. This will not affect the lawfulness of any processing carried out before you withdraw your consent.
12.1.7. Request restriction of processing of your personal data. This enables you to ask us to suspend the processing of your personal data if you want us to establish the data’s accuracy, if our use of the data is unlawful but you do not want us to erase it, if 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 if you have objected to our use of your data but we need to verify whether we have overriding legitimate grounds to use it.
12.2. If you wish to exercise any of the rights set out above, please contact us: dataprotection@cdtltd.co.uk. You do 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 could refuse to comply with your request in these circumstances.
12.3. 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.
12.4. We try to respond to all legitimate requests within one month. Occasionally it could take us longer if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated.
12.5. If you have any questions about this document or about the use of your personal data, or you want to exercise your privacy rights, please contact dataprotection@cdtltd.co.uk
12.6. You have the right to make a complaint at any time to the national authority: https://ico.org.uk/make-a-complaint/. We would, however, appreciate the chance to deal with your concerns before you approach the regulator, so please contact us in the first instance.
