Material Subprocessors

Last updated: May 29, 2026

The list below identifies the entities that may process Protected Health Information (PHI) on LivingPractice's behalf in the course of providing the Formation Agent and related services. LivingPractice maintains a Business Associate Agreement with each material subprocessor that meets the requirements of 45 CFR §164.504(e)(1)(ii) and §164.308(b).

Material subprocessors with access to PHI

Subprocessor Services Purpose BAA
Amazon Web Services, Inc. AWS Lambda
Amazon Aurora
Amazon Bedrock

Amazon CloudWatch Logs
Amazon API Gateway
AWS Secrets Manager
AWS KMS
API runtime, primary database, AI inference for the Formation Agent (Claude family of models via Bedrock), transactional email, monitoring and logging, edge routing, credentials storage, and at-rest encryption. Executed

All listed services appear on the AWS HIPAA Eligible Services Reference and are covered by the AWS Business Associate Agreement on file with LivingPractice.
About Stripe: LivingPractice uses Stripe to process subscription billing and payment information. No Protected Health Information is transmitted to or processed by Stripe. Stripe is therefore not a material subprocessor under this list.

Foundation model providers (sub-subprocessor relationship through AWS Bedrock)

Foundation model providers (currently Anthropic, for the Claude family of models) provide the model weights used through Amazon Bedrock. Per the architecture of Amazon Bedrock, these providers do not have access to LivingPractice's prompts, completions, or logs — Amazon Bedrock deep-copies the model into AWS-owned deployment accounts to which the providers do not have access. AWS and the model providers do not use LivingPractice's Bedrock inputs or outputs to train any model. See AWS Bedrock User Guide — Data Protection.

Update commitment. LivingPractice will update this list within 30 calendar days of the addition or removal of any material subprocessor with access to PHI, in accordance with §7 of LivingPractice's Business Associate Agreement.
