Terms of Service

Last updated: October 15, 2026

These terms govern your use of the Shopify app "JustFlow for LINE" (the "App") provided by LiveCommerce, the trade name of an individual sole proprietor ("we"). By installing the App, you agree to these terms.

1. The service

The App lets merchants who run a Shopify store (the "Merchant") send LINE messages to their own customers, for example from Shopify Flow. Messages are sent from the Merchant's own LINE Official Account.

2. Merchant responsibilities

• The Merchant provides their own LINE Official Account, Messaging API channel and LINE Login channel, and follows LINE's terms and guidelines.
• Before sending LINE messages to customers, the Merchant obtains the necessary consent and complies with applicable laws (data protection, e-commerce, advertising and labeling laws, and so on). The Merchant must not send messages to customers who have unlinked.
• The Merchant keeps credentials such as channel secrets safe and, if they may have leaked, reissues them in LINE and registers them again in the App.
• The Merchant is responsible for what they configure in Shopify Flow (text and recipients). Do not send spam, unwanted solicitation, illegal or harmful content, or content that infringes others' rights.

3. Prohibited use

• Interfering with the operation of the App, unauthorized access, or reverse engineering (except where the law allows it).
• Trying to access other Merchants' data.
• Using the App in violation of LINE's or Shopify's terms.

4. Fees

The App is currently free. If we introduce paid plans, we will tell you in advance and charge through Shopify billing.

5. Continuity and changes

• We may change or end features of the App with notice. We aim to give 30 days' notice of significant changes.
• The App may be unavailable temporarily because of maintenance, outages, or changes by LINE or Shopify. We do not guarantee uninterrupted operation.

6. Disclaimer and limit of liability

• We are not responsible for the content, delivery or customer response of messages sent through the App. Messages may fail because of LINE outages or an exceeded message quota.
• Except for intentional misconduct or gross negligence, our liability is limited to the Merchant's direct damages and capped at the amount the Merchant paid for the App in the previous 12 months (0 JPY while the App is free).

7. Termination and data

• The Merchant can stop using the App at any time by uninstalling it. On uninstall we delete the Shopify access token and the LINE channel secrets right away, and delete the remaining data when Shopify's deletion requests arrive. See the privacy policy.
• We may suspend use if the Merchant violates these terms.

8. Governing law and courts

These terms are governed by the laws of Japan. The Osaka District Court has exclusive jurisdiction in the first instance over disputes related to the App.

9. Changes

We may change these terms. If you keep using the App after a change, you agree to the change. We will give advance notice of significant changes.
