Privacy

Your chats stay on this Mac.

Familiar Local for macOS · Updated 25 October 2026

Information the app handles

Familiar does not collect or send personal information to the developer. No account is required. Chat history is stored in browser local storage on your Mac. Conversation context is held in memory while the local helper is running and resets when the helper stops.

On-device model and local connection

When you send a prompt, Familiar passes it to Apple Foundation Models through a local service on the same Mac. The helper listens only on 127.0.0.1 and is not exposed to your local network. Familiar does not send prompts or responses to a hosted AI service.

Apple Foundation Models requires a supported Mac, macOS 26 or later, Apple Intelligence, and a ready on-device model. Availability depends on Apple’s supported devices and languages.

Storage and deletion

Your chat history stays in local browser storage on this Mac. Use the chat controls to delete a conversation. Stopping Familiar clears the model context held in memory; it does not automatically delete saved chat history.

Support links

If you choose Support or Report an Issue, Familiar opens GitHub in your browser. Any information you choose to share there is handled under GitHub’s own privacy terms.
