Terms of Service — Dango Profile Fields

Last updated: 2026-10-05

These Terms govern your use of Dango Profile Fields ("the App"), provided by Dango Apps, a sole proprietorship operated by Kuniaki Kato in Japan ("we", "us"). By installing the App on your Shopify store, you ("Merchant") agree to these Terms and to our Privacy Policy.

1. The service

The App lets you add custom fields to your customers' account profile pages, store their answers as customer metafields in your store, export them, and trigger Shopify Flow. Features depend on your plan.

2. Plans and billing

• Plans are listed on our Shopify App Store page. Paid plans are billed monthly through Shopify, and Shopify's billing terms apply.
• You can change or cancel your plan at any time from the App. Refunds and prorated charges follow Shopify's billing rules.
• We may change prices with at least 30 days' notice. Changes take effect from your next billing cycle.

3. Your responsibilities

• You decide which fields to collect. You must have a lawful basis to collect that data and must tell your customers how you use it (for example, in your store's privacy policy).
• You must not use the App to collect payment card numbers, passwords, government ID numbers where prohibited, health data, or other sensitive data unless the law allows it and you have proper safeguards.
• You must follow Shopify's terms and all applicable laws.

4. Acceptable use

You must not use the App for illegal purposes, attempt to reverse engineer or disrupt it, overload it, or access other merchants' data.

5. Your data

You own your store data and your customers' data. Customer field values are stored in your Shopify store, not on our servers. We use your data only to provide the App, as described in the Privacy Policy and Section 9.

6. Availability and support

We aim to keep the App available and fix problems promptly, but we do not guarantee uninterrupted service. Changes to Shopify's platform or APIs may affect how the App works. Support is provided by email at support@dangoapps.com, usually within 2 business days (Japan time).

7. Uninstalling

You can uninstall the App at any time. When you do, Shopify removes the App's metafields, including your customers' saved answers, on its own schedule. Export your data to CSV first if you want to keep it. We delete our session data as described in the Privacy Policy.

8. Intellectual property

The App and its content belong to Dango Apps. You keep all rights to your store data and your customers' data.

9. Data Processing Terms

For personal data of your customers processed through the App ("Customer Data"):

1. Roles. You are the controller; we are the processor.
2. Instructions. We process Customer Data only to provide the App and on your documented instructions, which are these Terms and your configuration of the App.
3. Confidentiality. Only the operator of Dango Apps has access to Customer Data, and is bound by confidentiality.
4. Security. We maintain the measures described in the Privacy Policy, including encryption in transit and at rest, and restricted, two-factor-protected access.
5. Subprocessors. You authorize Shopify and our hosting provider (Fly.io, Inc., United States). We will give notice before adding a new subprocessor, and you may object by uninstalling the App.
6. Data subject requests. We will help you respond to customer requests to access, correct, or delete data, including through Shopify's customers/data_request and customers/redact webhooks.
7. Breach notification. We will notify you without undue delay, and within 72 hours where feasible, after becoming aware of a personal data breach affecting your Customer Data.
8. Deletion. We do not store customer field values on our servers; operational logs containing customer IDs are deleted after 30 days. We delete a customer's App field values on a customers/redact request, and delete our session data on uninstall, as described in the Privacy Policy.
9. Cross-border transfers. We rely on appropriate safeguards for transfers outside the country where data was collected.
10. Audit. On reasonable request, we will provide the information needed to show compliance with this Section.

10. Disclaimer

The App is provided "as is". To the extent permitted by law, we do not guarantee that it will meet every need or be free of errors.

11. Limitation of liability

To the extent permitted by law, our total liability for any claim is limited to the fees you paid us for the App in the 12 months before the claim. We are not liable for indirect or consequential losses, such as lost profits or lost data, except in cases of our intentional misconduct or gross negligence.

12. Suspension and termination

We may suspend or end your access if you break these Terms or misuse the App, with notice where reasonable. You may stop using the App at any time by uninstalling it. If we decide to discontinue the App, we will give at least 30 days' notice so you can export your data.

13. Changes to these Terms

We may update these Terms. For material changes, we will notify you at least 14 days in advance. Continuing to use the App after that means you accept the changes.

14. Governing law

These Terms are governed by the laws of Japan. The Tokyo District Court has exclusive jurisdiction as the court of first instance.
