Commitments

Six things we sign — not just promise. Each one is backed by a contract, a verifiable technical control, or a law that sanctions us directly if we fail.

  1. 01 Your data never trains third-party models

    Our AI model providers operate under zero-data-retention configurations: they process and return, they do not store or train. What the agent learns about your operation lives inside your organization only.

  2. 02 Never sold, never shared with advertisers

    Not your data and not your patients'. No exceptions, no fine print.

  3. 03 Every organization is a sealed box

    Isolation here isn't a software rule: it's infrastructure. Each organization runs on its own dedicated database, with data-ownership checks layered on every operation. Two institutions' data never mix — not to answer, not to predict, not to “improve the service.”

  4. 04 The person always knows

    The agent identifies itself as a virtual assistant at the start of every conversation and announces recording. Transparency is a legal requirement in the jurisdictions we serve — here it ships on by default and cannot be hidden.

  5. 05 Everything is audited

    Every conversation is recorded, transcribed, and audit-logged — who accessed what, and when. What the agent did can be verified, not taken on faith.

  6. 06 Verifiable deletion

    Export everything anytime (CSV/JSON). When the contract ends we delete your data and confirm it in writing. Custody of the medical record was, is, and will remain your institution's.

The data journey

Six steps between a patient dialing and the record resting under your control. This is what we walk technical committees through when they ask.

  1. The person calls or writes

    The patient dials your number or messages your WhatsApp. From the first packet the connection travels encrypted (TLS 1.2+ for data, encrypted voice media). The agent identifies itself as your institution's virtual assistant and announces recording before going on.

    TLS 1.2+Agent self-identifies

  2. Voice becomes text

    The conversation is transcribed in real time by voice-processing providers configured for zero data retention: they process the audio, return the text, and keep nothing. Where PHI is involved, they additionally operate under a BAA.

  3. The agent reads only your data

    To answer, the agent reads only your organization's configuration: services, schedules, rates, the protocols your committee approved. And the query lands on your organization's dedicated database — one institution can't see another's data even by mistake, because they don't even share a database.

    Dedicated databaseApproved answers only

  4. The model reasons, it doesn't memorize

    The language models and predictive models process under zero-retention arrangements and never train on your data. Predictions — who is at risk of a no-show, who to reach first — are computed only from your organization's data and only for your approved purposes.

    Zero trainingPredictions stay in-org

  5. Everything is stored — encrypted

    The recording, the transcript, and the structured fields of the conversation are stored encrypted at rest (AES-256) in your organization's dedicated database, behind role-based access control (RBAC), least privilege, and an audit log over every access. Our database and analytics providers operate under BAAs and SOC 2 Type II / ISO 27001 certification.

  6. You decide how long it lives

    Retention is configured by your institution according to its legal duties — your state's medical-record retention rules, for instance. Delete whenever you want: gone from active systems in ≤30 days and from backups in ≤90, with written confirmation.

Who answers for the data

Every legal department's first question: who is the controller and who is the processor? Your institution decides; we execute — and we're accountable.

Your institution

Covered Entity / Controller

  • Decides the purposes of processing and is responsible for patient notices and authorizations under the laws that govern it.
  • Always keeps custody of the medical record — Arbol operates on the systems you already use, without taking your data over.
  • Approves every flow the agent executes and defines retention.
  • Designates who on your team can access what, through role-based access control.

Arbol

Business Associate / Processor

  • Processes data only on your behalf and under documented instructions — never for its own purposes, never to sell, never to combine across customers.
  • Signs a HIPAA BAA with every covered customer and a DPA under U.S. state privacy laws — before the first record is processed.
  • Applies the Security Rule safeguards: encryption in transit and at rest, least privilege, audit logging, workforce training, and documented risk analysis.
  • Notifies breaches without unreasonable delay (60 days at most) and hands you everything your own notification duties require.

Document When it applies What it covers
BAA — Business Associate Agreement Every HIPAA-covered customer Permitted PHI uses, Security Rule safeguards, breach reporting, return or destruction of PHI at termination. Our PHI-touching subprocessors carry downstream BAAs — the complete chain of trust.
DPA — Data Processing Agreement U.S. state privacy laws Service-provider / processor role: documented instructions only, no selling, no sharing, no cross-customer combining, obligations flowed down to subprocessors.
NDA for documentation On request Under NDA we hand over the named subprocessor list, internal policies, and security-assessment summaries.

AI governance

Generative and predictive models under one governance, with risk management aligned with NIST AI RMF (Govern · Map · Measure · Manage).

  1. 01 It identifies itself, always

    A virtual assistant from the first sentence, on every channel. Required by U.S. state disclosure laws — “hidden” is not a setting here.

  2. 02 It doesn't make things up

    It answers only from the configuration your institution approved: services, rates, schedules, protocols. If it doesn't know, it says so — and escalates.

  3. 03 Real human oversight

    Alarm symptoms, delicate cases, and anything requiring judgment is handed to your team, with a summary and the collected data. The final clinical and administrative decision is always human and always yours.

  4. 04 It doesn't memorize outside

    Zero retention at the model providers and zero training on your data. Privacy by design and by default.

  5. 05 It predicts to care, never to sell

    Predictions — care gaps, no-show risk, who to reach first — are computed only from your organization's data, for approved care purposes. Using PHI to push commercial offers is “marketing” under the HIPAA Privacy Rule and would require the patient's written authorization — it is not part of the product's flows. A privacy impact study is available to your committee.

  6. 06 Everything is measured and on the record

    Every conversation is recorded, transcribed, and audited; agent performance is continuously evaluated. Risk management aligned with NIST AI RMF.

06

Subprocessors

Only the ones strictly necessary to operate, each under a back-to-back processing agreement and — where PHI is involved — a downstream BAA. The full named list is delivered under NDA, and we notify you before adding or replacing any of them.

Function Location Safeguards
Infrastructure & hosting U.S. SOC 2 / ISO 27001 cloud · DPA · BAA
Database & analytics U.S. BAA · SOC 2 Type II · ISO 27001 · dedicated DB per org
Telephony & messaging U.S. DPA · HIPAA-eligible configuration

Due-diligence questionnaire

The questions technical departments of clinics, hospitals, and insurers ask us — with the answers we put in writing. If one is missing, we answer it in writing in the due-diligence packet.

Encryption & infrastructure

How is data encrypted?
In transit, TLS 1.2 or higher on every connection. At rest, AES-256. Keys are managed in the cloud KMS, with rotation and envelope encryption.
Where is data hosted?
In U.S. data centers. Our database and analytics providers are SOC 2 Type II / ISO 27001 certified and operate under BAAs, on top of the data-processing agreements.
Are production and test environments separated?
Yes. Production and staging are separate, and real customer data never leaves production: it is not used in development or testing.

Access & authentication

Who can see my institution's data?
Only the people your institution authorizes, behind role-based access control (admin and member) and least privilege. On Arbol's side, production access is restricted, justified case by case, and recorded in the audit log.
Do you enforce MFA?
Arbol's team operates with mandatory MFA across all internal systems. For your team, the platform supports your identity provider's methods; enterprise SSO is enabled for customers that require it.
Is there an audit log?
Yes: who accessed which record, when, and from where, in centralized logs. Available to your privacy officer on request.

Retention, export & deletion

How long do you keep data?
Whatever your institution configures per its legal record-retention duties. Recordings, transcripts, and contacts can be deleted from the dashboard anytime.
What happens when I delete something — or when the contract ends?
Deleted data leaves active systems within 30 days and backups within 90. At contract end you export everything (CSV/JSON), we delete the rest, and we confirm it in writing.
Can I take my data if I leave?
Always. Full export in open formats, free and frictionless. Your data is never hostage to the contract.

AI & models

Do you train models on our data?
No. Never. Model providers operate under zero-retention configurations and contracts that prohibit training on your data. The agent's tuning to your operation lives isolated inside your organization.
Does data cross between customers?
Never — and not because of a software rule, but by architecture: every organization gets its own dedicated database, with data-ownership checks layered on every operation. Not to answer, not to predict, not for aggregate analytics.
Can the agent use a patient's diagnosis to offer them services?
To care for them, yes — to sell to them, no. Predictions drive clinical outreach: the overdue follow-up, the pending screening, the missed appointment. That is treatment and care coordination, which HIPAA permits. Using PHI for commercial offers is “marketing” under the Privacy Rule and requires the patient's prior written authorization — it is not part of the product's flows. The TCPA healthcare exemption likewise covers only non-telemarketing content.
What about veterinary clinics?
HIPAA protects human health information — veterinary records are not PHI, so the regime is much lighter. What still applies in full: protection of the owner's contact data, TCPA consent and opt-out rules for the calls themselves, and the same architecture (dedicated database, encryption, audit logging).
Do patients know they're talking to an AI?
Yes, from the first sentence and on every channel. It's required by several U.S. state laws — and it cannot be turned off here.
What if the agent doesn't know the answer?
It says so honestly and escalates to your team with the summary and data already collected. It doesn't improvise clinical or administrative answers: it answers only from your approved configuration.

Incidents & continuity

Do you have an incident response plan?
Yes: continuous monitoring, severity classification, containment, customer notification without undue delay, and a written post-mortem with root cause and fixes. The legal clocks are in the incidents section.
Backup & disaster recovery?
Automated backups encrypted to the same standard as live data, plus cloud-provider redundancy. Because each organization has its own dedicated database, point-in-time restore happens per organization, without touching anyone else. Recovery objectives (RTO/RPO) are documented in the due-diligence packet.
Do you run security testing?
Continuous vulnerability management with severity-based remediation and independent security assessments. Executive summaries are shared under NDA.

Compliance & paperwork

What do you sign with us?
A HIPAA BAA and a DPA for customers governed by U.S. law; an NDA for technical documentation; and, for customers under Colombian law, the Colombian data-transmission agreement. All of it before the first record is processed.
What certifications do you hold?
Honest answer: our infrastructure runs on SOC 2 / ISO 27001-certified clouds, and our own program is built on SOC 2's Trust Services Criteria and aligned with NIST CSF 2.0 and NIST AI RMF. Attestation status is shared under NDA. We say “certified” only when there's a certificate.
Do you give notice before changing a subprocessor?
Yes: prior notice to customers before adding or replacing a subprocessor, with the information your own compliance filings need.
08

Incident response

No system is infallible. What can be guaranteed is what happens in the hours that follow — and every deadline below is a legal or contractual duty, not a courtesy.

  1. Hour 0

    Detection & containment

    Continuous monitoring, severity classification, immediate containment. The clock starts — and we document everything from minute one.

  2. ≤ 72 hours

    We notify you

    Notification to the affected customer without undue delay: what happened, what data is involved, what we did, what's next. No euphemisms.

  3. ≤ 60 days

    HIPAA breach notification

    As a Business Associate, we notify the covered entity without unreasonable delay and within 60 days at most, with everything the Breach Notification Rule requires.

  4. Afterwards

    Written post-mortem

    Root cause, corrective actions, and security-program changes — in writing and available to your committee.

For customers under Colombian law, the SIC's incident clocks are in the Colombia version.

09
