Subprocessors

Last Updated: May 2026

Vallo uses certain third-party sub-processors to assist in providing our services. A sub-processor is a third party that processes personal data on behalf of Vallo in connection with delivering our product to customers.

The table below lists the sub-processors Vallo currently uses, the purpose for which each is engaged, the types of data transferred, and their primary location. Vallo contractually requires all sub-processors to maintain appropriate technical and organizational safeguards consistent with applicable data protection laws.

We will update this page when we add, remove, or materially change a sub-processor. Customers who have subscribed to notifications will receive advance notice of any such changes.
