Every company that touches customer data on our behalf, what it does and where it processes. This page forms Annex III of our Data Processing Addendum. We give 30 days' notice before adding or replacing anything on it.

How changes are notified

  • We publish the change on this page and update the “last updated” date.
  • We email the account owner at least 30 days before the new sub-processor begins processing.
  • You may object on reasonable data protection grounds within that window by emailing legal@westorably.com. The objection process is set out in section 6 of the DPA.
  • Emergency replacement of a sub-processor for security or continuity reasons may happen faster; we will notify you as soon as possible and your objection rights are unaffected.
