This is the chain we would want to see from anyone else. Each row is what that vendor does, the patient data it can reach, and where it processes it.
Retell AI
Live call audio, the speech-to-text transcript, and any clinical detail the caller volunteers during the conversation.The most sensitive vendor in the chain, because it holds the audio and the transcript rather than just metadata.
Voice agentProcessed in: United StatesAgreement: Direct BAA
Twilio
The phone number on both ends of the call, call duration and routing metadata, and the contents of any SMS sent back to the patient.On a Retell-managed number, Twilio operates as Retell's subprocessor and sits under Retell's agreement rather than a separate one. On a bring-your-own-carrier setup that is not true and a direct agreement is needed.
Telephony and SMSProcessed in: United StatesAgreement: Covered under Retell's BAA
Amazon Web Services
Stored patient records: name, callback number, the reason for the call, call transcripts and recordings, consent records and opt-out state.Consent and opt-out are enforced here by database constraints and a trigger rather than by application code, so a stray script or a hand-run query cannot bypass them.
Database and application hostingProcessed in: United States (us-east-2)Agreement: Direct BAA
Vercel
Anything submitted through a form on this website. No patient records, no call content: the clinic-facing application and its database are not hosted here.
Marketing website hosting and DNSProcessed in: United StatesAgreement: No patient data — BAA not required
Supabase
What you type into a form on this website: your name, your practice's name, your email address and your phone number. No patient records and no call content — the clinic-facing application and its database are not here.This is the sales enquiry record, not the product. A practice's own patients, calls and appointments are in Amazon RDS and never reach it.
Enquiry CRMProcessed in: United States (us-east-1)Agreement: No patient data — BAA not required
Google Workspace
Any patient detail that appears in an email notification sent to the practice, such as a message taken from a caller.
EmailProcessed in: United StatesAgreement: Direct BAA
Cal.com
The name, email address and chosen time of whoever books a demo on this site. That is a practice's own staff arranging a sales call, never a patient. It is not present on a call, in the agent, or on any page where a patient enters their details.Loads only on the demo page, and only because a visitor went there to pick a time. Unlike analytics it is available in every market, since a calendar someone deliberately opened is the service they asked for rather than observation they did not.

Google Tag Manager and Google Analytics
Pages viewed on this marketing site, plus the IP address and browser the request came from. It is not present on a call, in the agent, or on any page where a patient enters their details.Listed last because it never sees a call. It loads only in the markets named in our analytics policy and is absent from the rest, because those markets require opt-in consent that this site does not yet ask for.
