  1. More about the information we collect and why

We have a duty to process personal data fairly, lawfully and in a manner that you would expect given the nature of our relationship with you. Where we have a legal basis to use your personal data without consent (as set out in the table above), this policy fulfils that duty by giving you appropriate notice and explanation of the way in which your personal data will be used. Where consent is required for our use of your personal data we will ask you to positively opt-in.  

If you have any questions or require any further information regarding our use of your personal data please contact us at

  1. We will only use your personal data for the purposes for which we collected it, unless we reasonably consider that we need to use it for another reason and that reason is compatible with the original purpose. Please note that we may process your personal data without your knowledge or consent, in compliance with the above rules, where this is required or permitted by law.

  1. You acknowledge that, with your consent, we may share your personal data with other companies within our group to support us in the performance of our business activities.

  2. We may also share your personal data with other organisations, for example in the context of the possible sale or restructuring of the business. We may also need to share your personal data with a regulator or otherwise to comply with the law.

  3. Why else we might share your personal data. We may also share your personal data with other organisations where it is necessary in order to provide you with our service or where we have another legitimate interest in doing so that is not overridden by your interests and fundamental rights. For example, to protect our customers or to operate and maintain the security or our computer systems.  

  4. Who else may process my personal data. The following service providers and sub-contractors may process personal data about you for the following purposes:

  2. We will only retain your personal data for as long as is necessary to fulfil the purposes we collected it for, including for the purposes of satisfying any legal, accounting or reporting obligations.  For example, we may need to retain some of your personal data for 6 years after you have made a purchase from us for legal reasons.

  3. Unless we inform you otherwise (or you request that we erase your personal data) we will retain your personal data for as long as you continue to use our services and if you do not use our services for 6 years then we will delete all your information. In some circumstances we may anonymise your personal data so that it can no longer be associated with you, in which case we may use such information without further notice to you.
