Terms of service
Last updated: 2026-08-23
These terms govern your use of Atsurae (the app), operated by matoix. By installing or using the app you agree to them. If these terms conflict with Shopify's own terms for merchants or for apps, Shopify's terms take precedence.
Definitions
"App" means Atsurae, the Shopify app published by matoix, including its admin pages, background processing and public pages.
"Operator", "we" and "us" mean matoix, a sole proprietorship registered in Japan. Operator details are in the privacy policy.
"You" means the merchant who installs the app on a Shopify store, and anyone who uses the app on that merchant's behalf.
What the app does
The app prepares product data for Google Shopping. You write rules, preview which variants they would change, and apply them. The app then writes the resulting values to product and variant metafields in your store, and keeps a history so that a run can be reverted.
The app works entirely inside the Shopify admin. It does not read or store customer or order data, and it does not modify your storefront or theme. What it reads and stores is listed in the privacy policy.
The app is a tool that changes your product data on your instruction. It does not decide what your product data should be.
Conditions of use
You must hold a Shopify store in good standing and comply with Shopify's terms. You are responsible for everyone who uses the app through your store's staff accounts.
You may not reverse engineer the app, attempt to access it or its data outside the intended interfaces, interfere with its operation, or use it to break Shopify's or Google's policies.
We may suspend access for a store that breaks these conditions or that places an unreasonable load on the service.
Fees and billing
Plans and prices are shown on the app's listing in the Shopify App Store and inside the app. Charges are billed by Shopify through your Shopify account; we do not bill you directly.
Upgrades, downgrades, cancellation and any refund are handled by Shopify's billing system and Shopify's terms. Uninstalling the app ends the subscription as Shopify provides.
A change of plan can take a few minutes to be reflected inside the app.
Your responsibilities
Review the preview before you apply a run. The preview shows exactly which variants would change and to what; applying writes those values to your store.
The content of your rules, and the values they write, are your decision. You are responsible for making sure the values comply with the policies of Google Merchant Center and Google Ads.
The change history lets you revert a run, within the retention limits described in the privacy policy. It is not a backup of your store, and it does not cover changes made outside the app.
No warranty
The app is provided as is. We do not warrant that it is free of errors or that it will be available at all times. Maintenance and incidents can interrupt it.
The app depends on Shopify's and Google's platforms, which change. We do not warrant that any particular attribute will be accepted, displayed or used by Google Merchant Center or Google Ads, nor any advertising result.
Limitation of liability
To the extent permitted by law, our total liability to you for all claims arising out of the app, in any period, is limited to the fees you paid for the app in the 3 months before the event giving rise to the claim. If you are on a free plan, that amount is zero.
We are not liable for indirect or consequential loss, lost profit, lost revenue, lost advertising opportunity, or loss of data that you could have preserved by reviewing a preview or keeping your own records.
These limits do not apply to loss caused by our wilful misconduct or gross negligence, or where the law does not allow them to be limited.
Intellectual property
The app, its code, design and documentation belong to the operator. Your product data belongs to you; we use it only to provide the app, as described in the privacy policy.
Data
What the app reads, stores, for how long, and how to have it deleted is described in the privacy policy, which forms part of these terms.
Changes to the service and termination
We may change or add features without notice, and may remove a feature with notice inside the app.
If we discontinue the app, we will give at least 30 days' notice inside the app and on the help page. Values already written to your store stay in your store; data held by the app is deleted as described in the privacy policy.
Changes to these terms
If these terms change, this page is updated and the date at the top changes with it. Continuing to use the app after a change means you accept the new terms. For a change that reduces your rights, we will also show a notice inside the app.
Governing law, jurisdiction and language
These terms are governed by the laws of Japan. Any dispute arising from them is subject to the exclusive jurisdiction of the Osaka District Court as the court of first instance.
These terms are written in Japanese and English. If the two versions differ, the Japanese version prevails.
