Privacy

Privacy architecture

The privacy of your data is the fundamental principle of DOCU.expert. Unlike other AI chatbots, we have designed our architecture from the ground up to ensure that your documents never leave your control.

Our privacy promise

  • Your documents are never sent to third parties
  • Your data is never used to train AI models
  • Processing 100% local on the desktop app
  • Servers exclusively in the European Union

Processing modes

DOCU.expert offers two operating modes, each with different privacy features:

The embeddings model runs on your CPU/GPU. Vectors are stored in a local database.
