Overseas transfers and sharing personal data with sub-processors

Specifically, our group companies and our website servers are located in the EU and UK, however, some of our third-party service providers, and partners operate around the world. This means that when we collect your personal data, we may process it in a number of different countries.
However, we have taken appropriate safeguards to require that your personal data will remain protected in accordance with this privacy policy. These include implementing the International Data Transfer Agreement (IDTA) and the UK international data transfer addendum to the European Commission’s standard contractual clauses for international data transfers (UK Addendum) for transfers of personal data between us and each of our sub-processors, which requires all sub-processors to protect personal data they process from the UK in accordance with UK data protection laws. Our IDTA and UK Addendum are available on request.
In the event we cannot or choose not to continue to rely on either of those mechanisms at any time we will not transfer your personal data outside the UK unless we can do so on the basis of an alternative mechanism or exception provided by UK data protection law and reflected in an update to this policy.
