Privacy Architecture

Most AI tools send your data
to servers you don't control.

Haide stores your selected document knowledge locally and does not route call content through Haide middle servers. Relevant context may be sent directly to OpenAI when used for a document-grounded answer.

Call audio, transcripts, prompts, and AI responses do not route through Haide servers

"Haide does not operate middle servers for call audio, transcripts, prompts, or AI responses. Activation uses Haide's website server to retrieve your license, while call content goes directly to the providers you configure with your own API keys."
