None of these providers may use customer data to train models. Each one is bound by data protection terms equivalent to the DPA. Transfers to the United States rely on the EU–US Data Privacy Framework or on Standard Contractual Clauses.
Changes to this list are announced on this page with a new effective date, and by email to tenant administrators, at least 30 days before they apply. Administrators may object as set out in the DPA.
Providers that process data about site visitors or billing (analytics, email delivery, payment) and not customer documents are listed in the privacy notice.
