1. What this page is
Syrena Ltd uses third-party service providers (subprocessors) to help provide the Syrena Service. A subprocessor may process personal data on our behalf, always under a contract that holds it to obligations consistent with our Privacy Policy.
Where a subprocessor is outside the UK/EEA, we rely on the safeguards described in the international transfers section of our Privacy Policy, such as the UK IDTA and EU Standard Contractual Clauses with the UK Addendum.
