8-1. AI-Powered Conversation (OpenAI API)

The Service may provide an AI-powered conversation feature that generates responses using a third-party AI service provider (OpenAI API). When you use this feature, the text you enter (and limited recent conversation context, if provided) may be transmitted to OpenAI to generate a response.

• No direct identifiers: we do not intentionally send your email address, Firebase UID, or other directly identifying personal information to OpenAI for response generation.
• No conversation storage by us: we do not store AI conversation content in our database after a response is generated.
• Voice features: any speech-to-text or text-to-speech functions in the Service may use your browser’s Web Speech API (not OpenAI).
• Third-party terms: your use of this feature may be subject to OpenAI’s applicable policies and technical safeguards.

9. Disclaimer and Limitation of Liability

The Service is provided on an "as is" and "as available" basis. Certain outputs (including AI-generated conversation responses) may be inaccurate, incomplete, or inappropriate.

To the maximum extent permitted by law, the Operator is not liable for indirect, incidental, or consequential damages.

10. Governing Law and Disputes

These Terms are governed by the laws of the Republic of Korea, unless otherwise required by applicable law. Any disputes shall be resolved through good-faith consultation, and if necessary, through the competent court.
