How KAY handles your firm's data
The vendor agreements that back our work, written in plain English.
Our approach
Law firms hold things people can't afford to have leak. Medical records. Criminal histories. Financial details. Family situations. KAY was built to handle that material with care. This page explains how, and which vendor agreements we have in place to back it up.
VENDOR AGREEMENTS
Business Associate Agreement with Anthropic
A.I. Esquire has signed a Business Associate Agreement (BAA) with Anthropic, the developer of the AI models that power KAY. Under this agreement, Anthropic processes data passed to its models on our behalf subject to confidentiality, use-limitation, and security obligations consistent with HIPAA's requirements for AI service providers.
In plain English: when KAY handles a call, an intake, or a document, the AI side of that work is done under a contract that limits how the data can be used and obligates secure handling.
We are working to put equivalent agreements in place with the rest of our infrastructure providers, and will update this page as additional BAAs are executed.
IMPORTANT TO KNOW
A BAA is one piece of compliance, not the whole picture
A Business Associate Agreement with one vendor is not a substitute for a complete HIPAA compliance program. If your firm handles Protected Health Information, you remain responsible for your own compliance, including risk assessments, written policies, workforce training, and BAAs with all of your vendors that touch PHI.
We are happy to share our executed BAA with Anthropic for your records, and to walk through how KAY fits into your firm's compliance posture.
