Sub-processors

Last updated: 2026-07-29

PureBox uses the third-party service providers listed below (sub-processors) to deliver the service. Each sub-processor processes customer data only as necessary for the stated purpose.

Current sub-processors

OpenAI is our current AI classification sub-processor and receives limited Gmail-derived metadata (such as sender, subject, and label signals) to classify messages. PureBox does not offer a HIPAA Business Associate Agreement, and mailboxes used for regulated healthcare work are outside the scope of the Service.
