Subprocessor list.

Last reviewed · October 17, 2026

Summary

DIAL3D uses a small set of subprocessors to operate the service. Every subprocessor that may handle PHI is under a signed Business Associate Agreement with DIAL3D. This page lists them by category. The full list, with each provider named, is provided with your BAA and on request from hello@dial3d.ai.

Cloud hosting and storage

Amazon Web Services (AWS), United States: backend services, database, file storage, encryption key management, logging, and delivery of sign-in codes. Under BAA.

Edge network

Global edge network for the website, the chat agent and parts of voice call handling. Serves traffic from the location nearest each visitor. Under BAA.

AI model providers

Large language model inference for the voice, chat, SMS and email agents and for DIAL3D Next, including AI services that run inside our own AWS account. Under BAA. Customer data is not used to train AI models.

Voice, telephony and speech

Telephone carriers for calls and text messages, real-time voice transport, speech-to-text and text-to-speech providers. Under BAA.

Email

Secure email delivery for handoffs and alerts, and our workplace email. Under BAA.

Channels and systems customers connect

Social messaging platforms, when a customer connects them, carry the messages patients choose to send through those platforms.

CRM, call tracking, EHR and insurance verification systems that a customer connects are the customer's own vendors. DIAL3D reads from and writes to them with the customer's credentials.

Advertising platforms connected through DIAL3D Comply receive conversion events with health information removed.

Billing

Payment processor for subscription billing. No PHI.

Change notification

We notify customers in advance of adding new subprocessors that will handle PHI. Customers can opt out of new subprocessors within a reasonable transition window.

The current list, with each provider named, is available on request from hello@dial3d.ai. We update this page when the list changes.
