This page lists the third-party service providers we use to operate our services, and what each of them provides on our behalf. It exists because vendor relationships change more frequently than our core privacy policy should: by maintaining this list here, we can add or remove subprocessors without republishing our primary legal documents, while ensuring you always have transparent visibility into who they are.
Each of these companies works with us under a Data Processing Agreement (DPA) and acts strictly in accordance with our instructions.
Infrastructure
| Company | What it provides | Location |
|---|---|---|
| Cloudflare, Inc. | Hosting, content delivery, and contact form databases for this website and our applications | Edge network in the EU and worldwide |
| Hetzner Online GmbH | Virtual Private Servers (VPS), dedicated servers, and hosting infrastructure running our applications and data services | EU (Germany, Finland) |
| netcup GmbH | Virtual Private Servers (VPS) and hosting infrastructure running internal systems and backend services | EU (Germany, Austria) |

Language Models
Certain applications of ours send text to language model providers to generate outputs—such as suggestions, summaries, or translations. Where such text may contain personal data, the service-specific schedule to our Privacy Policy explicitly identifies it. No data from datanius.com itself is sent to any of these providers.
| Company | What it provides | Location |
|---|---|---|
| OpenRouter, Inc. | Request routing to underlying model host providers | USA |
| Fireworks AI, Inc. | Model inference execution | USA |
| Z.ai (Zhipu AI) | Model inference execution | Outside the EEA |
| Google LLC (Gemini API) | Osmičky: word suggestions and embeddings — words typed into dictionaries or drawn from our word corpus and language codes | USA |
OpenRouter operates as a router: it forwards requests to one of several contracted providers. For any request that could potentially involve personal data, we explicitly fix the specific endpoint provider ourselves rather than letting it be chosen dynamically, ensuring the table above remains exhaustive.
We strictly prohibit all of these providers from using our submitted data to train their models.
Transfers Outside the EEA
Several of these companies process data outside the European Economic Area. In such cases, cross-border transfers rely on the European Commission’s Standard Contractual Clauses (SCCs) and, for United States entities, the EU–US Data Privacy Framework where the company is certified under it. Hetzner Online GmbH and netcup GmbH process and store data strictly within European Union data centers. You may contact us for further details.
