EmpfangoStrong platforms with a European limitation
US platforms such as Retell AI, Vapi and Bland AI are technically strong and particularly popular with developers – but for European companies with GDPR obligations, US-based data processing creates concrete legal hurdles. This article explains the relevant differences objectively, based on the providers' public privacy documentation (as of June 2026), and outlines what a GDPR-compliant EU alternative must deliver.
Retell AI: what their own compliance documentation says
Retell AI states in its own compliance documentation verbatim: "We do not currently operate services within the European Union." According to its Privacy Policy, data is "primarily stored and processed in the United States." In fairness: a DPA is available via self-service, and standard contractual clauses (SCCs) are referenced for international transfers.
For European companies, this means: usage is technically possible but requires active assessment of whether SCCs adequately cover your risk profile – especially in sensitive sectors such as healthcare or legal services.
Vapi: pricing model and contract access
At Vapi, processing takes place in the United States according to its Privacy Policy. A DPA is only available for enterprise customers – not accessible for smaller users without upgrading. "Zero Data Retention" is available as a paid add-on at US$1,000 per month. In addition, Vapi's Privacy Policy reserves the right to use recordings and transcripts for model training: "to help train and improve the AI models."
For European companies this matters: the consent to training use must be reconciled with your own data protection obligations toward callers.
Bland AI: compliance badge and contractual reality
Bland AI displays GDPR as a compliance badge. However, the Privacy Policy itself does not reference EU standard contractual clauses and contains consent to US data transfers. Data residency controls are only available in the enterprise tier.
In practice, this means smaller and mid-sized companies cannot obtain a contractual basis for a GDPR-compliant third-country transfer from the standard plans.
The structural CLOUD Act consideration
Regardless of individual privacy documents, all US providers are subject to the CLOUD Act: US authorities can require US companies to produce data, even if it is stored on EU servers. This is not an accusation of bad intent – it is a structural characteristic that should be factored into the risk assessment when handling sensitive business data.
An important distinction: the relevant risk level is who your contracting party is. If you use Retell, Vapi or Bland directly, your contracting party is itself a US company. Empfango also uses US sub-processors for individual functions (telephony, speech recognition, speech synthesis) that are subject to the CLOUD Act – openly documented in the privacy policy and safeguarded by EU Standard Contractual Clauses. Your contracting party, the language model and the hosting remain in Germany and the EU.
What a EU alternative must deliver
- EU data processing for speech recognition, language model and storage – demonstrably documented, not merely claimed.
- A DPA under Art. 28 GDPR without an enterprise threshold – available to all customers, not only from a certain volume.
- No training use of call data – the voices and content of your callers must not be used to improve AI models.
- No permanent audio storage as the default – call audio should either not be stored at all or only buffered briefly.
- EUR pricing – predictability without currency risk and without hidden per-minute meters.
Empfango as an alternative from Germany
Empfango (IQONEX GmbH, Erfurt) is an AI phone assistant built for the European legal framework. Hosting runs in Frankfurt (EU); the language model is Azure OpenAI in the EU region. Call audio is not stored permanently. A DPA under Art. 28 GDPR is included in every plan, including the smallest. Pricing: €99 to €499 per month as a EUR flat rate, cancellable monthly, 30-day money-back guarantee.
In the interest of transparency: Empfango also uses services from US providers for telephony, speech recognition and speech synthesis – specifically Twilio, Deepgram and ElevenLabs. This is openly documented in the privacy policy and contractually secured via DPAs with standard contractual clauses. The difference from Retell, Vapi and Bland lies in the EU language model (Azure OpenAI EU), the open sub-processor documentation, the audio storage default (no permanent storage) and the DPA available to all customers.
Also worth considering: Synthflow
Synthflow (AgentFlow AI GmbH, Berlin) is a German company and also targets the B2B market as a developer platform. Pricing is listed in US dollars; the primary audience is developer teams and enterprise customers. Businesses looking for a ready-made SME solution with EUR flat-rate pricing and without custom integration development are more likely comparing Empfango, Placetel AI or VITAS (as of June 2026).
Conclusion
Retell, Vapi and Bland are strong options for technical teams without strict EU data protection requirements. For European companies that need a DPA without an enterprise threshold, no audio-storage default and an EU language model, switching to an EU-native solution is worthwhile. Empfango offers all of this – cancel monthly, no setup fee, 30-day money-back guarantee.
