1. Data Controller
Name: Tóth Gergő EV
Address: 1163 Budapest, Máté u. 2., Hungary
Email: info@medivox.hu
Website: https://getmedivox.com
2. Purpose and Scope
This Privacy Policy informs data subjects about the data processing activities carried out within the MediVox service (getmedivox.com website and app.medivox.hu application) in accordance with Regulation (EU) 2016/679 (General Data Protection Regulation, "GDPR") and Hungarian Act CXII of 2011 on the Right of Informational Self-Determination and Freedom of Information.
3. Categories of Personal Data
3.1 Website Visitors
- IP address, browser type, operating system
- Visit timestamp, pages viewed
- Cookie-related data (see Cookie Policy)
3.2 Demo Requesters
Data provided during a demo request:
- Phone number
- Name
- Email address
- Clinic name
3.3 Application Users (Doctors, Clinics)
- Registration data (name, email, phone)
- Clinic data (name, address, opening hours, treatments)
- Calendar data (via Google Calendar sync)
- Billing data
3.4 Patients (AI Call Handling)
- Phone number
- Name (if provided)
- Appointment booking data (requested time, treatment type)
- Call recording (transient processing only)
4. AI-Based Call Handling and Transparency
MediVox operates an AI-based phone assistant that automatically answers and handles incoming calls. Pursuant to Article 13(2)(f) and Article 22 of the GDPR, we inform data subjects:
- Every AI-handled call begins with a clear disclosure that the caller is speaking to an automated system.
- The AI is used exclusively for appointment booking and information purposes; it does not provide medical advice.
- The caller may request a transfer to a human agent at any time.
- The AI's decision-making (appointment suggestion) is not solely automated under Article 22, because the final confirmation is performed by the user (clinic).
5. Legal Basis for Processing
| Purpose | Legal basis (GDPR Article 6) |
|---|---|
| Website operation, cookies | Consent (a); Legitimate interest (f) — necessary cookies |
| Demo request processing | Consent (a) |
| Service provision (app) | Performance of contract (b) |
| AI call handling, appointment booking | Performance of contract (b); Legitimate interest (f) |
| Invoicing | Legal obligation (c) |
6. Health Data
The MediVox system applies the special category data rules of GDPR Article 9. The AI assistant processes only appointment booking data (treatment type, requested time) and does not request, store or process medical diagnoses, lab results or medical history.
Naming a treatment type (e.g. "dental check-up") does not in itself constitute health data under Article 9 GDPR if no direct inference about the data subject's health status can be drawn from it. Nevertheless, the system follows the data minimisation principle.
7. Data Processors
| Processor | Purpose | Location / Data storage |
|---|---|---|
| Hetzner Online GmbH | Server hosting | EU (Germany, Finland) |
| OpenAI, L.L.C. | LLM for AI call handling (GPT family) and speech-to-text (gpt-4o-transcribe) | USA — under SCCs; OpenAI Zero Data Retention; API data not used for model training |
| Anthropic, PBC | LLM for AI call handling (Claude family) | USA — under SCCs; API data not used for model training |
| Deepgram, Inc. | Speech-to-text | USA — under SCCs |
| ElevenLabs Inc. | Text-to-speech | USA — under SCCs |
| Cal.com Inc. | Appointment booking, calendar sync | USA — under SCCs |
| Vercel Inc. | Website and form-handler hosting (Frankfurt region) | USA — under SCCs; processing in EU |
| Google Ireland Ltd. (Google Workspace) | Demo request confirmation and notification emails (hello@medivox.hu) | EU (Ireland) / global |
| Cloudflare, Inc. | Bot and spam protection (Turnstile) on forms | USA — under SCCs |
Demo lead CRM storage runs on a self-hosted system (Twenty CRM) operated within the EU — this is part of the Controller's own infrastructure, not a third-party processor.
A Data Processing Agreement (DPA) compliant with GDPR Article 28 is in place with each processor.
8. Google Calendar Integration and Google User Data
The MediVox application offers an optional integration with Google Calendar to two-way synchronise the clinic's Google calendar with MediVox-managed appointments. Google user data handling complies with the Google API Services User Data Policy, including its Limited Use requirements.
8.1 Google User Data Accessed
When the clinic admin connects their Google account, MediVox requests the following OAuth scopes:
https://www.googleapis.com/auth/calendar— read/write access to the connected Google account's calendar events.https://www.googleapis.com/auth/userinfo.email— the connected Google account's email address.openid— the Google account's stable identifier (added automatically by Google).
8.2 How Google User Data Is Used
- Calendar scope (
auth/calendar): creating, updating, reading and deleting appointment events in the clinic's selected Google calendar, corresponding to MediVox bookings, modifications and cancellations. Sync is bidirectional: changes made directly in Google Calendar are synced back into MediVox via Google's push-notification webhook. - Email scope and OpenID: displaying which Google account is connected in the MediVox UI, and associating the integration with the correct MediVox tenant (clinic).
Google user data is not used for:
- serving advertisements,
- training, fine-tuning or evaluating AI/ML models (including third-party LLM, speech-to-text or text-to-speech providers),
- any purpose other than the calendar sync described above.
8.3 Sharing and Onward Transfer
Google user data is not sold, rented or traded. Onward transfer to third parties occurs only:
- To infrastructure processors strictly necessary to operate the service — specifically Hetzner Online GmbH (EU-based server hosting). Google user data is stored encrypted at rest. This processor is listed in section 7 above.
- To meet legal obligations (lawful request from a court or authority), or to protect the rights, property or safety of MediVox, its users or the public.
Google user data is not shared with MediVox's AI subprocessors (speech-to-text, text-to-speech and LLM providers). Those providers receive only the patient's spoken audio during a call and the structured appointment metadata produced by our application logic; they never access Google Calendar event contents, the connected Google email address or the OpenID identifier.
8.4 Retention and Deletion
Google user data is retained only while the clinic maintains the Google integration. The clinic admin may disconnect at any time from Settings → Integrations in the MediVox application; MediVox's access can also be revoked directly at https://myaccount.google.com/permissions. On disconnect, the stored OAuth refresh token is deleted from our database; MediVox will make no further Google API calls on behalf of the clinic. Previously synced appointment records are kept as part of the clinic's operational records for the period stated in section 10.
8.5 Contact for Google User Data Questions
For questions or deletion requests regarding Google user data, contact us at hello@medivox.hu.
9. International Transfers
Primary data storage takes place on servers within the EU (Hetzner, Germany/Finland). For processors based in the USA, transfers are made under the European Commission's approved Standard Contractual Clauses (SCCs).
10. Retention Periods
| Data type | Retention |
|---|---|
| Call recordings | Deleted automatically after processing (max. 30 days) |
| Demo request data | 6 months, or until the data subject requests deletion |
| User account data | Term of contract + 5 years (accounting obligation) |
| Appointment booking data | 1 year, or as configured by the clinic |
| Cookies | See Cookie Policy |

- Right of access (Article 15)
- Right to rectification (Article 16)
- Right to erasure (Article 17)

- Access management and logging
- Regular security reviews
