4. How Do We Protect Personal Data if we transfer it internationally?

We may transfer your personal data outside of the EEA and/or UK. Some of these recipients are located in countries in respect of which either the European Commission and/or UK Government (as and where applicable) has issued adequacy decisions, in which case, the recipient’s country is recognized as providing an adequate level of data protection under UK and/or European data protection laws (as applicable) and the transfer is therefore permitted under Article 45 of the GDPR.

Some recipients of your personal data may be located in countries outside the EEA and/or the UK for which the European Commission or UK Government (as and where applicable) has not issued adequacy decisions in respect of the level of data protection in such countries (“Restricted Countries”). For example, the United States is a Restricted Country. Where we transfer your personal data to a recipient in a Restricted Country, we will either:

  • enter into appropriate data transfer agreements based on so-called Standard Contractual Clauses approved from time-to-time under GDPR Art. 46 by the European Commission, the UK Information Commissioner’s Office or UK Government (as and where applicable); or
  • rely on other appropriate means permitted by the EU/UK GDPR, which establish that such recipients will provide an adequate level of data protection and that appropriate technical and organizational security measures are in place to protect personal data against accidental or unlawful destruction, loss or alteration, unauthorized disclosure or access, and against all other unlawful forms of processing.

You may ask for a copy of such appropriate data transfer agreements by contacting us using the contact details above.
