Security & privacy

Your knowledge stays your knowledge.

FRANZ is built so that sensitive material – laws, internal guidelines, experience knowledge – stays protected. GDPR-compliant, processed in the EU, and with clear access control.

Your data stays with you

Your original documents remain on your own server. FRANZ never trains AI models on your content. Chat histories are deleted after a retention period you choose.

No model training GDPR by design Deletion window 1 day – 12 months Right to access & erasure

Processed in the EU

The application, vector database and AI processing all run in the EU. The language models are EU-hosted and accessed through the European AI gateway Opper.ai.

Access under your control

Three clearly separated roles and strict tenant isolation: every request is firmly bound to your organisation – no one sees another organisation's data. Passwords with Argon2id, transmission over TLS 1.3.

Traceable, not guesswork

FRANZ answers questions solely on the basis of the documents you have released – and cites the source for every answer. If it finds nothing solid, it says so honestly instead of guessing. Uploaded documents are treated as data, never as instructions to the AI (protection against prompt injection).
