You may opt out of this use by contacting us at support@foyl.dev.
We share data with the following third-party processors to operate the Service. Each processes data only as necessary for their specific function:
| Provider | Purpose | Data Shared | Privacy Policy |
|---|---|---|---|
| Anthropic (Claude API) | AI language model for dialectic responses and concept extraction | Conversation messages, document content, system prompts | anthropic.com/privacy |

We do not sell, rent, or trade your personal information to any third party. We do not use your data for advertising purposes.
Your conversation content is sent to Anthropic's Claude API in real time to generate dialectic responses. Anthropic's API does not retain conversation data for model training by default. However, we encourage you to review Anthropic's privacy policy and API terms for the most current information on their data handling practices.
Plus subscribers may optionally use Ollama, a locally hosted AI model. When using Ollama, conversation data is processed on the server infrastructure you or we configure and is not sent to any third-party AI provider.
