This page lists current Sub‑processors engaged by QuantKey and describes how we’ll notify customers of changes.
Definitions. “Sub‑processor” means a third party engaged by QuantKey that processes Personal Data on behalf of Customer to provide the Services (e.g., hosting, telephony, email delivery, support tooling).
How we add or change Sub‑processors
We’ll post updates here and email subscribers at least 30 days before a new Sub‑processor processes Personal Data, except for emergency replacements (in which case we’ll notify as soon as practicable).
Objections. If you reasonably object (e.g., data protection risk that can’t be mitigated), contact [email protected] within the notice window. We’ll work in good faith to resolve; if not feasible, you may suspend the impacted feature or terminate it without penalty.
