Orders and product sales use only basic data supported by these four roles. Restricted buyer PII, FBM shipping labels and purchaser invoicing are outside scope.

For Yahoo! Shopping merchants

Order API

Order status and order operations within permitted processing scope, without retaining purchaser histories.

Product API

Read, register and update your store’s products, subject to the non-retention policy for API-supplied information.

Inventory API

Check and update inventory for each store without relying on saved API copies.

Inquiry API

Review and reply to inquiries within permitted scope, without retaining messages or purchaser information.

We do not retain any Yahoo! Shopping purchaser personal information, without exception. Order numbers, related identifiers, products, statuses and inquiry text that may identify a purchaser are subject to the same restriction. They are excluded from databases, files, logs, caches, backups and persistent sessions. Other information supplied by LY Corporation through the Shopping Store API or test API is also not retained unless LY Corporation separately instructs its storage. Such instructions apply only to other information and never to purchaser personal information. Any instructed storage is limited to specified fields, purposes and periods.

Features involving purchaser information follow lawful store instructions and the non-retention obligation in Article 10. Temporary memory processing is limited to what is necessary, and information is discarded when processing ends. It is never recorded in databases, logs, caches, queues, files or backups. Purchaser-data storage, file exports and saved shipping labels are outside the feature scope.

Yahoo! Shopping requires store reauthorization every four weeks. We notify the registered email before expiry and stop the affected store’s API processing when authorization expires. Processing resumes after reauthorization and verification of the store, permissions and connection.

SECURITY & DATA PROTECTION

Only the necessary data, handled safely.

Amazon Japan postal codes are handled only in memory and discarded before logs or storage. Yahoo! Shopping purchaser personal information is never retained. Encryption, least privilege and store separation are mandatory security-policy requirements.

Privacy Policy / Information Security Policy

Employees and approved contractors located in Japan may access Amazon data for service operation, store-requested support, troubleshooting and security. Access is limited to authorization information, store operational data and sanitized logs necessary for the task, restricted by staff member, store and task using least privilege, and logged and supervised. Data is not used for our own advertising, external AI training or disclosure to other stores. Access, processing, disclosure and outsourcing outside Japan are prohibited.
