Treasure Castle AI(Relationship AI)について / About Treasure Castle AI (Relationship AI) — 最終更新 / Last updated: 2026-09-16

1. 運営者 / Operator

このAIチャットは 合同会社スタイルフリー(Treasure Castle 運営)が提供しています。

This AI chat is provided by STYLE FREE LLC (合同会社スタイルフリー), the operator of Treasure Castle.

2. AIチャットで扱う情報 / Information handled by the AI chat

Your typed messages and selected language; an anonymous visitor ID stored in your browser (a random UUID; no name, email or Shopify customer ID — the server keeps only an irreversible transform of it); conversation history (message text and timestamps) to keep the conversation going; only with your memory consent, the items you explicitly ask the AI to remember (see below); consent records (when memory was enabled or stopped) and records of whether a memory was used in a reply; when you use the AI while logged in to the store, the customer ID that Shopify signs and forwards (used to continue as the same customer; no password or payment data is received); your connection IP address for abuse prevention (used only transiently for rate limiting, not stored).

3. AIを利用する目的 / Why we use AI

Answering your questions and guiding you to products, stock and shipping information; personalising the conversation only if you have enabled memory; security and abuse prevention (rate limiting, signature verification, replay protection).

4. 記憶機能(永続メモリー) / Memory (persistent memory)

Memory is separate from normal chat and is not enabled just by chatting; it is enabled only when you choose "Use memory". Only what you explicitly ask the AI to remember is stored — nothing is inferred and stored automatically. Sensitive content (health, income, address, phone number, card numbers, passwords, etc.) is not stored even if requested. You can list and delete memories at any time from "Review / delete memories", or by telling the chat to forget something. Choosing "Stop memory" stops new memories and stops using existing ones in replies; stopping does not delete existing memories, so delete them from the list if you no longer want them (a memory that is not used for 365 days is deleted automatically). Memories are kept within the Treasure Castle scope and are never automatically combined with other businesses or services.

5. 保存期間 / Retention

Explicitly saved memories are retained for 365 days from the last time each memory is used. If a memory is used again in a conversation, its retention period is renewed from that date. A memory that has not been used for 365 days is automatically deleted. Deletion by you takes effect immediately. Conversation history is automatically deleted 90 days after the last conversation. Consent records are retained for 3 years from their last update. Operational logs (memory usage records and events) are automatically deleted after 90 days. Contact us below if you would like earlier deletion.

6. 外部AIサービスの利用 / External AI processing

回答の生成には OpenAI のAIサービスを利用します。送信するのは、あなたのメッセージ(直近の会話履歴を含む)、記憶機能が有効な場合に関連する記憶、商品検索の結果、およびAIへの指示文です。利用者ID・Shopifyのお客様ID・メールアドレス・氏名は送信しません。送信は、OpenAI側に会話内容を保存させない設定(store=false)で行っています。

ご注意: パスワード、クレジットカード番号、認証コード、マイナンバーや運転免許証番号などの本人確認情報は、チャットに入力しないでください。

Replies are generated using OpenAI's AI services. We send your messages (including recent conversation history), relevant memories when memory is enabled, product search results, and our instructions to the AI. We do not send your visitor ID, Shopify customer ID, email address or name. Requests are sent with the setting that asks OpenAI not to retain the conversation content (store=false). Please do not enter passwords, credit card numbers, authentication codes, or government ID numbers into the chat.

6-2. 音声機能 / Voice features

Standard voice uses your browser's speech recognition and speech synthesis. When browser speech recognition is used, how the audio is processed follows the specifications of your browser/OS (some browsers process it on the vendor's servers). Our paid cloud voice is not used. Premium voice, only when you choose it, may use OpenAI's speech APIs (recognition and synthesis). If a verified Treasure Castle customer has at least one qualifying purchase in the last 90 days, Premium voice is available for up to 10 minutes regardless of purchase amount. Anonymous users and customers without a qualifying purchase have no free Premium voice allowance. Remaining time is calculated from cloud speech processing time and is recalculated automatically on refunds or after 90 days. Premium voice may pause when our operational limits are reached (standard voice and text continue). To calculate Premium voice availability we read your orders from the last 90 days (order date, payment status, paid amount) read-only; this is never sent to external AI services.

7. 国外での処理 / International processing

上記の外部AIサービスおよびサーバーは日本国外(米国など)で運用されている場合があります。詳細は当店の プライバシーポリシー をご覧ください。

The external AI service and our servers may operate outside Japan (for example in the United States). See our Privacy Policy for details.

8. 事業ごとの扱い / Business scope

Treasure Castle のAIで扱う会話・記憶は Treasure Castle の範囲内で管理します。SUGO など合同会社スタイルフリーの他のサービスとの情報の統合は、あなたの別途の明示的な同意なしには行いません(現在、統合機能は提供していません)。

Conversations and memories from the Treasure Castle AI are managed within the Treasure Castle scope. They are not combined with other STYLE FREE services (such as SUGO) without your separate, explicit consent (no such linking feature is currently offered).

9. あなたができること / Your controls

Enable or stop memory (in the chat screen); list and delete individual memories ("Review / delete memories", or tell the chat to forget); use the chat without memory; request deletion of conversation history and consent records via the contact below.
