Handling of Personal Information in the Chatbot Feature

The chatbot feature of the Site collects and uses information as follows.

(1)Information collected and stored

  • The content of users' questions and the responses (stored in a database)
  • A value obtained by hashing the source IP address with an irreversible algorithm (the IP address itself is not stored)
  • Session identifier (a temporary identifier for each browser tab)
  • Date and time of use

(2)Temporary retention of conversation history

To maintain continuity of the conversation, the conversation history is kept in the server cache for 30 minutes from the last access. It is automatically deleted after 30 minutes.

(3)Transmission to an external AI service

The chatbot uses the Claude API (a generative AI service) provided by Anthropic, PBC, a U.S. corporation ("Anthropic").

  • Data sent: the user's questions and the conversation history within the same session
  • Destination: United States (this constitutes provision to a third party in a foreign country)

This external transmission is explained in the notice displayed when the chatbot starts, and users are deemed to have consented to it when they send a message.

Chatbot logs are retained for two years from the date of collection and then deleted.
