Data residency
EU and US datacenters, GDPR-compliant, EU-only routing on request. Merius does not store prompts or completions and does not train on them.
Merius runs in EU and US datacenters and is GDPR-compliant. You can route to the EU only, and we never store your prompts or completions.
Where requests run
By default, requests are served from the nearest healthy region. Choose EU-only routing so a request is processed and kept in EU datacenters — useful when data must not leave the EU.
Retention & training
We do not store your prompts or completions, and we do not train on them. Traffic is encrypted with TLS in transit. A signed Data Processing Agreement (DPA) is available for customers with a GDPR processing relationship.
EU residency and zero retention are part of why we run our own hardware rather than reselling someone else's cloud — the data path is ours end to end.
Use with your tools
Point Cursor, Cline, Claude Code, and Continue at Merius. Because the API is OpenAI-compatible, set the base URL and key — no custom plugin.
Security
Keep Merius API keys safe — read them from environment variables, use a key per environment, rotate periodically, and keep keys server-side.
