Privacy Policy

This English-language version is the authoritative and legally governing version of this document.

1. Controller (Art. 4 No. 7 GDPR)

Fabian Ilg · Lucid AI Labs
Kirchbergstraße 5, 93152 Markt Nittendorf
Bavaria, Germany
Email: [email protected]

An officially appointed data protection officer is not currently named. The obligation to appoint pursuant to Art. 37 para. 1 lit. c GDPR (core activity = processing of special categories of data pursuant to Art. 9) is continuously assessed. Until regular processing of health data in the voice agent service begins, requests are handled directly by the controller; before the onboarding of the first paying clinic, an external data protection officer is appointed. A written threshold assessment ("not large scale" assessment for the pre-clinic period) is documented internally.

A record of processing activities pursuant to Art. 30 para. 2 GDPR (record of processing activities as a processor, kept separately per clinic controller) is maintained and provided to the supervisory authority (BayLDA) on request.

2. General Notes on Data Processing

We process personal data only insofar as this is necessary for the provision of the website and our services and a lawful basis pursuant to Art. 6 GDPR (and, additionally, Art. 9 GDPR for health data in the voice agent context) exists. No data processing takes place for the advertising purposes of third parties, no profiling for automated individual decisions (Art. 22 GDPR).

3. Collection on Visiting the Website

3.1 Server Logs

On every page request, technical information is automatically collected by the hosting provider Vercel (server logs):

IP address (in truncated form, insofar as technically possible)
Date and time of access
Requested URL and HTTP status code
User agent (browser type and version)
Referrer URL (if transmitted)

Lawful basis: Art. 6 para. 1 lit. f GDPR (legitimate interest in security, stability, abuse protection). Storage duration: 30 days, then automatic deletion by the host. A profile with personal data is not created from these logs.

3.2 Hosting

The hosting of the website is carried out via Vercel Inc. (USA), the clinic dashboard and the voice agent database via Hetzner Online GmbH (Falkenstein/Nuremberg, Germany). Third-country transfers for Vercel are safeguarded by SCC and the DPF (see § 8). The application-side data of the voice agent clinic is located exclusively in the EU.

4. Cookies and Consent Management

We use cookies and comparable storage technologies only to the extent that this is permissible pursuant to § 25 TDDDG (formerly § 25 TTDSG):

Necessary (always active): language-selection cookie (local storage), the cookie-consent cookie (lucid-consent, local storage). Lawful basis: § 25 para. 2 No. 2 TDDDG (technically required).
Analytics (only after consent): Microsoft Clarity (see § 13). Lawful basis: § 25 para. 1 TDDDG in conjunction with Art. 6 para. 1 lit. a GDPR (explicit consent).
Marketing: currently not in use. If marketing trackers are loaded in the future, we will ask again.

Before each consent, no non-necessary cookies are set and no trackers are loaded (no pre-consent tracking). Microsoft Clarity is initialised with clarity('consent', false). In this mode, according to Microsoft documentation, Clarity collects no data whatsoever and sets no cookies. Only after explicit consent (click on "Accept") is the flag set to true and Clarity begins data collection. The implementation is verified against the official Microsoft documentation (learn.microsoft.com, Cookie Consent). Consent can be withdrawn at any time via the footer ("Cookie settings"). The withdrawal takes effect immediately, the flag is reset to false and no further data flow to Clarity takes place.

The Reject button and the Accept button are visually presented as equal in the banner (no dark pattern), in accordance with the EDPB Guidelines 03/2022 on deceptive design patterns in cookie banners as well as the requirement of voluntary consent pursuant to Art. 7 GDPR.

5. Contact Form and Email Contact

Data transmitted via the contact form at /contact or directly by email to [email protected] (name, email, company, message, optional: budget, timeframe) is used exclusively for the processing of your enquiry.

Lawful basis: Art. 6 para. 1 lit. b GDPR (pre-contractual measures / contract performance), for purely informational enquiries additionally Art. 6 para. 1 lit. f GDPR (legitimate interest in handling enquiries).
Storage location: Hetzner-hosted Supabase (Falkenstein/Nuremberg, DE) as well as email server (Resend for transactional mail, see § 7).
Storage duration: 36 months from the last interaction, then deletion or anonymisation. On conclusion of a contract: statutory retention periods (e. g. AO, HGB).

6. Voice-Agent-Specific Processing

Within the scope of the voice agent service, we process personal data of callers on behalf of the respective clinic (processing on instruction pursuant to Art. 28 GDPR). The controller for this processing is the clinic itself; Lucid AI Labs is the processor. The master DPA is available at /avv.

This privacy policy describes the voice agent processing only in overview; the legally binding detail clauses are in the DPA.

6.1 Data Flow of a Typical Call

Call ingress via Telnyx (USA, SCC + DPF) on a clinic-specific German geo telephone number.
AI announcement at the beginning of the call (see § 6.4), generated via ElevenLabs (USA, SCC).
Speech input to text via Deepgram (USA, SCC), low latency, transient.
Conversation logic (LLM) via Anthropic Claude (USA, SCC, no training with input data).
Response as speech via ElevenLabs, back via Telnyx to the caller.
Persistence of the transcript and the appointment data in Supabase on Hetzner (DE, EU data residency).
Appointment confirmation by email (if the caller provides an address) via Resend (USA, SCC + DPF).

6.2 Lawful Bases

General data (name, telephone number, appointment): Art. 6 para. 1 lit. b GDPR (initiation of a treatment contract).
Health data within the meaning of Art. 9 para. 1 GDPR, insofar as the caller voluntarily discloses such: Art. 9 para. 2 lit. h GDPR (processing for healthcare provision).
Optional audio recording (only if activated by the clinic): Art. 6 para. 1 lit. a GDPR (explicit consent at the beginning of the call).

6.3 Professional Secrecy (§ 203 StGB)

The clinic, as a professional secrecy holder within the meaning of § 203 StGB, expressly authorises, on each conclusion of a contract, Lucid AI Labs as well as all sub-processors named in the sub-processor list as "assisting persons" pursuant to § 203 para. 3 and 4 StGB. The confidentiality obligation is contractually safeguarded.

6.4 AI Announcement (AI Act Art. 50)

At the beginning of every call, the Voice Agent plays a clearly intelligible notice that the caller is interacting with an AI system (example: "You are speaking with the AI telephone assistant of the practice Dr. X. If you would like to speak with a human, please say 'human'."). This obligation arises from Art. 50 AI Regulation (EU) 2024/1689. The applicability of this article begins on 2 August 2026; Lucid AI Labs already fulfils it now.

6.5 Recording (§ 201 StGB)

A permanent audio recording does not take place by default. Voice data is only processed transiently (streaming) and deleted immediately after generation of the transcript. If a clinic explicitly commissions an additional audio recording in the main contract, a separate consent is obtained at the beginning of every call; in the event of objection, the recording is immediately and verifiably deactivated. A recording without notice and possibility of objection does not take place under any circumstances; this would be a criminal offence pursuant to § 201 StGB.

6.6 Functional Limitation

The Voice Agent provides no diagnosis, performs no triage and gives no medical assessments. For any substantive medical concern, an escalation to a human takes place. This limitation avoids a classification as high-risk AI pursuant to Annex III of the AI Regulation.

7. Processors and Recipients

We use the following processors. The complete current list with addresses, data categories and DPA links is available at /sub-processors/.

Provider	Seat	Purpose	Transfer basis
Hetzner Online GmbH	DE	Hosting database, transcripts	EU, no third-country transfer

We do not sell, rent or lend personal data to third parties for advertising purposes.

8. Third-Country Transfers (Art. 44 ff. GDPR)

Transfers to the USA to the recipients named in § 7 take place on the following bases:

Standard contractual clauses of the EU Commission pursuant to Implementing Decision (EU) 2021/914 (modules 2 and, where applicable, 3).
Insofar as the recipient is certified: reliance on the adequacy decision EU-U.S. Data Privacy Framework of 10 July 2023 (e. g. Telnyx, Resend, Microsoft, Vercel, Anthropic).
Transfer Impact Assessments (TIA) were carried out for each US recipient, in particular with regard to FISA 702 / Executive Order 12333. The TIA documents are available for inspection on request.

9. Storage Duration

Server logs (Vercel): 30 days, then automatic deletion.
Contact enquiries: 36 months from the last interaction.
Voice agent audio data: transient, max. 60 seconds buffering.
Voice agent transcripts: 90 days (adjustable per clinic).
Appointment records: until expiry of the clinic-side retention obligation.
Optional audio recording (if activated): 30 days, then irretrievable deletion.
Microsoft Clarity: 13 months (standard, see § 13).

10. Your Rights (Art. 15–22 GDPR)

Access (Art. 15): Which data do we have about you?
Rectification (Art. 16): Correction of inaccurate data.
Erasure (Art. 17): "Right to be forgotten", insofar as no retention obligation exists.

No automated individual decision (Art. 22): No solely automated decision with legal effect takes place.

To exercise these rights: email to [email protected] with subject "Data protection access request". Response within the statutory period of one month (Art. 12 para. 3 GDPR), in complex cases extendable by two further months with reasoning.

11. Right to Lodge a Complaint with the Supervisory Authority (Art. 77 GDPR)

You have the right to lodge a complaint with a supervisory authority. Competent for the seat of the controller:

Bavarian State Office for Data Protection Supervision (BayLDA)
Promenade 18, 91522 Ansbach
Telephone: +49 (0)981 180093-0
Email: [email protected]
Web: lda.bayern.de

You can also contact any other EU supervisory authority, in particular the one competent in your state of residence.

12. Newsletter and Marketing

We currently operate no newsletter and no advertising email processing. Should this be introduced in the future, an explicit, documented double-opt-in consent takes place. Data is then not used for marketing purposes without explicit consent (§ 7 UWG).

13. Microsoft Clarity (Web Analytics, Opt-In)

We use Microsoft Clarity for the anonymous analysis of heatmaps and click patterns, exclusively after explicit consent. Provider: Microsoft Corporation, One Microsoft Way, Redmond, WA 98052, USA.

Data types: click position, mouse movement, scroll behaviour, browser type, screen resolution, language/locale information. Microsoft anonymises IP addresses before storage. We configure Clarity without Recording mode for sensitive areas.
Lawful basis: § 25 para. 1 TDDDG in conjunction with Art. 6 para. 1 lit. a GDPR. Before consent, Clarity is initialised with clarity('consent', false); the script sets no cookies before the flag switches to true. Source: Clarity Consent Mode (Microsoft Docs).
Storage duration: 13 months (Microsoft standard).
Third-country transfer: SCC + DPF (Microsoft is DPF-certified).
Anti-fingerprinting: We do not use any fingerprinting that goes beyond what Microsoft itself uses against bot traffic.
Withdrawal: at any time via the footer link "Cookie settings".

14. Anti-Fingerprinting Obligations

We refrain from browser fingerprinting, canvas fingerprinting and similar techniques for unique re-identification. Technical tracking pixels of third parties are not used. An identification of individual visitors is, on the basis of the collected data, neither intended nor practically possible.

15. Changes to This Policy

Material changes are announced at the top of this page with a new "as of" date and version number. Changes only take effect for future processing; retroactive changes are not made. In case of doubt, existing customers are additionally informed by email.

16. Contact for Data Protection Matters
