Overview

Hearth AI is designed with privacy as a core principle. All language model inference runs entirely on your device. We do not collect, transmit, or store your conversations, documents, or personal data on any external server.

Data Collection

Hearth AI does not collect any personal data. Specifically:

• No analytics or tracking SDKs are included.
• No user accounts or sign-in are required.
• No data is transmitted to our servers or any third party.

On-Device Data

The following data is stored locally on your device and is never transmitted externally:

• Conversations: Chat history is stored on-device using SwiftData.
• Models: Downloaded GGUF model files are stored in your app's local storage.
• Documents: Any documents imported for Q&A are processed and stored locally.
• Conversation Memory: The personal knowledge base is stored locally and can be exported as JSON.

Network Usage

The app connects to the internet only for:

• Hugging Face Hub: Browsing and downloading GGUF models. No personal data is sent during these requests.

Third-Party Services
