Effective: May 3, 2026 · Company: Lease Bot (leasebot.co.kr)

Article 1 (Purpose)

These Terms aim to clarify the conditions, procedures, rights, obligations, and responsibilities between the Company and the user regarding the Service.

Article 2 (Definitions)

1. "Service" means the Telegram-based managed AI bot intermediary service provided by the Company.
2. "User" means the individual or corporate customer using the Service under these Terms.
3. "External AI Provider" means third-party providers of AI models intermediated by the Company (Anthropic, OpenAI, Google, etc.).
4. "Bot" means the AI auto-response program that interacts with users via Telegram.
5. "Message" means one message/request sent by a user to the bot.

Article 3 (Nature of the Service — Intermediary)

1. The Company does not own or operate its own AI models. It is a business that intermediates and resells the official APIs of External AI Providers.
2. All responses, judgments, and outputs generated by the bot are produced by External AI Provider models; the Company merely transmits and intermediates them.
3. The Service may be affected by changes in External AI Provider policies, models, pricing, or availability.

Article 4 (Effect and Modification of Terms)

1. These Terms take effect upon posting on the Company's website.
