# Subprocessors and service providers

> Who helps Mythos operate the service, what they process, and where.

**Mythos Software, LLC** uses the providers below to operate Mythos. Their role depends on the service and data involved. The [Privacy Policy](/legal/privacy) covers our controller activities; the [Data Processing Agreement](/legal/data-processing-agreement) covers customer personal data processed on documented instructions.

Providers are identified by service name; their applicable contracting entities are defined in Mythos's provider agreements. An infrastructure region describes the deployment, not a promise that all support, control-plane processing or downstream subprocessors stay in that country.

## Core platform and customer-content processing

## Changes

For customer processing under our DPA, we give at least thirty days' advance email or in-product notice of a new or replacement subprocessor, with the objection process described in that agreement. Publication here alone is not proof that individual notice was delivered. Urgent security or continuity changes follow the DPA's specific exception.
