What we do to protect your data, which providers touch it, and — just as important — what we don't claim.
Last updated July 24, 2026
For customers that are covered entities, we act as a business associate and will sign a Business Associate Agreement. The assistant never gives medical advice, keeps conversations to scheduling and general information, and captures minimal protected health information.
An honest note:there is no such thing as being “HIPAA certified.” HIPAA compliance depends on your entire environment — your policies, your staff, your other vendors — not on any single product. We provide HIPAA-aligned design and a signed BAA; the obligations remain shared. See our HIPAA page.
The service can record and transcribe calls. Recording law varies by state: several require the consent of every party, not just one. Deciding what disclosure your callers need, and putting it in your greeting, is your responsibility as the business receiving the calls. Your greeting is fully editable in Settings for exactly this reason. We cannot give legal advice on which rule applies to you.
These providers process data on our behalf:
| Provider | Purpose | Data processed |
|---|---|---|
| Vapi | Voice call orchestration and recording | Call audio, recordings, transcripts, caller number |
| Twilio | Telephony (phone numbers, call delivery, SMS) | Caller and recipient numbers, call metadata, SMS content |
| Deepgram | Speech-to-text transcription | Call audio |
| ElevenLabs | Text-to-speech voice | Assistant response text |
| Anthropic | AI model powering the assistant | Conversation text and approved knowledge-base context |
| Voyage AI | Knowledge-base embeddings | Knowledge-base document text |
| Supabase | Application database and storage | Account, call log, request, and knowledge-base data |
| Vercel | Application hosting | Request metadata and logs |
| Stripe | Payment processing | Billing contact and payment details |
| SendGrid | Transactional email | Recipient email address and message content |
Customers under a BAA may request the current list and its status at any time.
The assistant answers from your knowledge base and the live conversation. We do not use your call content or knowledge-base content to train our own models, and our model provider processes it only to generate a response for that call. The assistant is instructed never to invent details — if your content doesn't answer a question, it says so and offers to take a message.
If a certification is required for your procurement, tell us and we will be straight about where we stand.
If you believe you have found a security issue, email hello@voiceboxmd.com with details and steps to reproduce. Please give us a reasonable opportunity to remediate before public disclosure. We do not pursue researchers who report in good faith and avoid privacy violations and service disruption.
