Data handling and processing

HuggingChat uses Hugging Face’s Inference Providers to access models from multiple partners via a single API. Depending on the model and availability, inference runs with the corresponding provider.

Security and routing facts

Hugging Face does not store any user data for training purposes.
Hugging Face does not store the request body or the response when routing requests through Hugging Face.
Logs are kept for debugging purposes for up to 30 days, but no user data or tokens are stored in those logs.
Inference Provider routing uses TLS/SSL to encrypt data in transit.
The Hugging Face Hub (which Inference Providers is a feature of) is SOC 2 Type 2 certified. See https://huggingface.co/docs/hub/security.

External providers are responsible for their own security and data handling. Please consult each provider’s respective security and privacy policies via the Inference Providers documentation linked above.

Technical details

The app is completely open source, and further development takes place on the huggingface/chat-ui GitHub repo. We're always open to contributions!

You can find the production configuration for HuggingChat here.

HuggingChat connects to the OpenAI‑compatible Inference Providers router at https://router.huggingface.co/v1 to access models across multiple providers. Provider selection may be automatic or fixed depending on the model configuration.
