The plugin collects and stores abandoned cart information (such as customer email and cart item details) locally in the merchant’s WordPress database for cart recovery purposes. Additionally, it transmits customer text queries to the OpenAI API (via HTTPS) to generate chatbot replies, and sends order/cart alert notifications to the merchant’s admin Telegram/LINE OA channels via official HTTPS APIs. No personal data is stored on external servers other than transient processing on official API channels.
