Hetzner. Falkenstein and Nuremberg. ISO 27001 + SOC 2 Type II. No US Cloud Act.
anymize runs exclusively on European infrastructure. Not at a US company with a data center in Frankfurt. But at a European hosting provider (Hetzner Online GmbH, Germany), in EU data centers, under EU data protection law. Your data is subject to no foreign access regime. No Cloud Act. No FISA 702. No EU-US Data Privacy Framework interpretation gymnastics.
Where your data lives
No parent company abroad, no Frankfurt server with a Californian registered address. A European company (Hetzner, Germany), operating in EU data centers, under EU data protection law.
Hetzner is one of Europe\u2019s leading hosting providers \u2013 headquartered in Gunzenhausen, Bavaria (Germany). European company, European commercial register, EU tax ID. That\u2019s not a detail, it\u2019s the foundation of every compliance argument: the operator is subject to EU law, not to foreign jurisdictions.
Our data sits in two Hetzner locations in Germany: Falkenstein/Vogtland \u2013 primary site, the largest Hetzner data center with several independent buildings. Nuremberg \u2013 secondary site for redundant components. Both locations are entirely within the EU. No shadow replication to non-EU countries. No \u201cglobal region\u201d that includes a node outside Europe.
Backup strategy: daily backups, geo-redundant and mirrored within the EU. Availability SLA: 99.9 % (enterprise SLAs negotiable). Data-protection-relevant specialty: no node outside the EU, not even in a backup-failover scenario.
Hetzner data centers run on 100 % renewable energy. For customers running ESG reporting, the corresponding certificates are available. That may sound like a side topic \u2013 it isn\u2019t: anyone maintaining CO\u2082 inventories often only gets rough \u201ccarbon neutrality\u201d claims from US hyperscalers. At Hetzner, the energy source is specifically nameable.
Certifications
The Hetzner data centers where anymize runs are externally audited and carry the relevant industry standards:
Important context
These certificates apply to the data centers, not automatically to the anymize platform itself. For anymize’s own certifications, see our certification roadmap further down.
No US Cloud Act
The location of the server does not determine who can access the data.
What matters is who owns the company that operates the server. That is the misconception running through most compliance discussions.
The structural difference
The legal situation in brief
The US CLOUD Act (Clarifying Lawful Overseas Use of Data Act, 2018) and FISA Section 702 oblige US companies to hand over data on request by US authorities – regardless of where the data physically resides. That affects:
The CJEU ruled in Schrems II (2020) that US surveillance law is incompatible with the GDPR. The EU-US Data Privacy Framework (2023) does not change that in substance – data protection officers and supervisory authorities continue to advise structural independence over formal workarounds.
What that means for you
Every anymize component runs on European infrastructure at a European-owned company (Hetzner, Germany). No US parent company, no corporate-group clause, no access scenario via third countries. Your data is subject exclusively to EU data protection law – and therefore to the GDPR’s protection standards without interpretation risk.
This applies to our own models Waterfall and Fountain at 100 %: the models run in our European infrastructure, the data never leaves the EU. For international frontier models (GPT, Claude, Gemini), automatic anonymization solves the problem: the data is anonymized before it leaves the European data center – which takes it out of the scope of the US Cloud Act.
Data flow
Transparency about the actual data flow is the foundation for audit evidence and DPO conversations. In brief:
Components in the EU
with us on Hetzner (Falkenstein and Nuremberg, Germany)
The three-stage PII detection runs entirely within the EU.
The mapping between placeholder and original data (for rehydration) is stored exclusively within the EU.
Waterfall and Fountain are operated by us; inference happens within the EU.
All user-specific content sits on Hetzner.
Florentin.ai (also GRVITY group, Kiel, Germany).
Components that may be external providers
only with anonymization upfront
OpenAI, Anthropic, Google, Mistral, Perplexity, Moonshot – called only when you explicitly choose them. Sensitive data is automatically anonymized before transmission. What the model sees are placeholders.
Mistral, European provider – for live transcription, self-hosted by us in the EU.
For image creation, external models (currently Nano Banana, OpenAI Image) are used; prompt content is anonymized beforehand if necessary.
The clear rule
Original data never leaves the EU.
What arrives at external models is either already anonymized content or content without personal reference. That’s not marketing – it’s the architectural core decision that makes Cloud Act protection possible in the first place.
Our own certification roadmap
The Hetzner data centers are certified. For the anymize platform itself (the application layer) we are working on our own certifications:
Standard evidence, often a minimum requirement in tenders
in preparation, planned for 2026Continuous controls review, for enterprise deals
in preparation, planned for 2026German government-cloud gold standard; also recognised by regulated industries across Europe
planned for 2027For active tenders or audits, we provide enterprise customers with the full TOM documentation (technical and organizational measures) and a completed security questionnaire on request.
Transparency note
Certifications are processes, not button presses. We communicate target dates honestly and will actively inform you about delays. No silent slips.
