Masking happens on our German servers – before any data reaches LLM providers. The LLM never sees your real data.
Request comes in - To our EU server
Masking in Germany - Sensitive data is replaced with tokens
Only tokens to LLM - OpenAI/Anthropic sees "[NAME_a1b2]", never real data
Unmasking - Response with real data returned to you
