Superstack

Terms of use

Effective date: May 12, 2026

1. Acceptance of Terms

These Terms of Use ("Terms") constitute a legally binding agreement between Gallery 6 ("Superstack", "we", "us", or "our") and the merchant or business entity that installs, accesses, or uses any Superstack application ("you" or "Merchant"). By installing or using any Superstack app you agree to be bound by these Terms. If you do not agree, you must not install or use our apps.

2. Description of Service

Superstack develops and operates Shopify applications ("Apps") that enable merchants to communicate with their customers through third-party messaging channels, including WhatsApp and other services provided by Meta Platforms, Inc. ("Meta"). The Apps integrate with your Shopify store and with third-party platforms to facilitate the sending and receiving of messages on your behalf.

3. Merchant Responsibilities

You are solely and exclusively responsible for your use of the Apps and for ensuring that your use complies with all applicable laws, regulations, and platform policies. Specifically:

  • Consent. You must obtain all legally required consents, opt-ins, and permissions from your customers before sending any message through the Apps, including marketing, transactional, and operational messages. You must maintain verifiable records of such consents and provide them to us or to any regulatory authority upon request.
  • Legal compliance. You are solely responsible for ensuring that your use of the Apps complies with all laws and regulations applicable in your jurisdiction and in the jurisdictions of your customers, including without limitation the General Data Protection Regulation (GDPR), the Telephone Consumer Protection Act (TCPA), Canada's Anti-Spam Legislation (CASL), the Protection of Personal Information Act (POPIA), the Prevention of Electronic Crimes Act (PECA), and any other data protection, privacy, or electronic communications laws. Superstack makes no representation that the Apps are appropriate or lawful for use in any particular jurisdiction. You assume all risk associated with the legality of your use.
  • Lawful basis. You warrant that you have a lawful basis for processing your customers' personal data and for sending messages to them through the Apps.
  • Third-party platform policies. You must at all times comply with Meta's WhatsApp Business Policy, Meta's Terms of Service, and any other policies of third-party platforms used by the Apps. You are responsible for obtaining and maintaining your own WhatsApp Business Account (WABA) and any associated approvals.
  • Opt-outs. You must promptly honor all opt-out, unsubscribe, and deletion requests from your customers, as required by applicable law and applicable platform policies.
  • Accuracy. You are responsible for the accuracy, legality, and appropriateness of all content and messages sent through the Apps.

4. Prohibited Uses

You must not use the Apps to:

  • Send unsolicited messages (spam) or messages to recipients who have not given the required consent.
  • Violate any applicable law, regulation, or the rights of any third party.
  • Transmit content that is unlawful, harmful, threatening, abusive, harassing, defamatory, obscene, or otherwise objectionable.
  • Violate Meta's WhatsApp Business Policy or any other third-party platform policy.
  • Attempt to circumvent any rate limits, access controls, or security measures.
  • Resell or sublicense access to the Apps without our prior written consent.

5. Data Processing

In providing the Apps, Superstack processes personal data of your customers on your behalf. In this context, you are the data controller and Superstack is a data processor. As data controller, you are responsible for ensuring there is a lawful basis for processing, for providing required privacy notices to your customers, and for fulfilling data subject rights requests. Our processing of personal data is governed by our Privacy Policy, which forms part of these Terms. The full scope of Superstack's obligations as data processor — including sub-processor details, breach notification timelines, and audit rights — is set out in our Data Processing Agreement, which also forms part of these Terms.

You must not submit to the Apps any personal data for which you do not have authority to process, or that violates any applicable law.

6. Shopify Platform

The Apps access your Shopify store data solely to provide the service you have requested. We do not sell your store data or use it for any purpose unrelated to operating the Apps. Your use of the Shopify platform is governed by Shopify's own Terms of Service, and Shopify's terms take precedence over these Terms for all matters relating to the Shopify platform itself.

7. Third-Party Services

The Apps depend on third-party services including Meta's WhatsApp Business Platform, Shopify, and other infrastructure providers. We have no control over these services and are not responsible for:

  • Outages, degradation, or unavailability of third-party services.
  • Changes to third-party APIs, policies, or pricing that affect the Apps.
  • Suspension or termination of your WhatsApp Business Account or any other third-party account by the relevant platform provider.
  • Failure of messages to be delivered due to third-party platform limitations or decisions.

8. Billing and Data Retention

Subscription fees for the Apps are billed through Shopify App Pricing. All billing matters, including charges, refunds, and disputes, are governed by Shopify's terms and are handled by Shopify. We are not responsible for billing errors or disputes arising from the Shopify billing system.

Upon uninstallation of an App or termination of your subscription, your store data will be retained for up to 30 days to allow for reinstallation, after which it will be permanently deleted in accordance with our Privacy Policy.

9. Intellectual Property

The Apps, including all software, designs, trademarks, and content, are and remain the exclusive property of Superstack and its licensors. Nothing in these Terms transfers any intellectual property rights to you.

By using the Apps, you grant Superstack a limited, non-exclusive, royalty-free license to access and process your store data solely as necessary to operate and improve the Apps for your benefit.

10. Disclaimer of Warranties

THE APPS ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY LAW, SUPERSTACK EXPRESSLY DISCLAIMS ALL WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND UNINTERRUPTED OR ERROR-FREE OPERATION. SUPERSTACK DOES NOT WARRANT THAT THE APPS WILL MEET YOUR REQUIREMENTS, THAT MESSAGES WILL BE DELIVERED, OR THAT YOUR USE OF THE APPS IS LEGALLY COMPLIANT IN YOUR JURISDICTION.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL SUPERSTACK BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING LOSS OF PROFITS, LOSS OF DATA, BUSINESS INTERRUPTION, OR REGULATORY FINES AND PENALTIES, ARISING OUT OF OR RELATED TO YOUR USE OF THE APPS.

IN ANY CASE, SUPERSTACK'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE APPS SHALL NOT EXCEED THE TOTAL FEES PAID BY YOU TO SUPERSTACK IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE CLAIM.

SUPERSTACK SHALL HAVE NO LIABILITY WHATSOEVER FOR ANY DAMAGES, FINES, OR PENALTIES ARISING FROM YOUR FAILURE TO COMPLY WITH APPLICABLE LAWS, YOUR FAILURE TO OBTAIN REQUIRED CONSENTS, OR YOUR VIOLATION OF THIRD-PARTY PLATFORM POLICIES.

12. Indemnification

You agree to indemnify, defend, and hold harmless Superstack and its officers, directors, employees, and agents from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or relating to:

  • Your failure to obtain required consents from your customers.
  • Your failure to comply with any applicable law or regulation, including data protection and electronic communications laws.
  • Your violation of Meta's WhatsApp Business Policy or any other third-party platform policy.
  • Any content or messages sent by you through the Apps.
  • Your breach of these Terms.

13. Force Majeure

Superstack shall not be liable for any failure or delay in performance caused by circumstances beyond our reasonable control, including outages or policy changes by Meta, Shopify, or other infrastructure providers, internet disruptions, acts of government, natural disasters, or other force majeure events.

14. Termination

We may suspend or terminate your access to the Apps at any time, with or without notice, if we believe you have violated these Terms, any applicable law, or any third-party platform policy. You may terminate your use of the Apps at any time by uninstalling them from your Shopify store. Sections 3, 5, 9, 10, 11, 12, and 16 of these Terms survive termination.

15. Dispute Resolution

Before initiating any legal action against Superstack, you agree to provide written notice to us at hello@superstack.ltd describing the dispute in reasonable detail, and to engage in good-faith negotiations for at least 30 days in an attempt to resolve the dispute informally.

16. Governing Law

These Terms shall be governed by and construed in accordance with the laws of Pakistan, without regard to its conflict of law principles. Any disputes not resolved informally shall be subject to the exclusive jurisdiction of the courts of Pakistan.

17. Changes to Terms

We may update these Terms from time to time. When we make material changes, we will update the effective date at the top of this page and, where practicable, provide notice through the Apps or by email. Your continued use of the Apps after the updated Terms take effect constitutes your acceptance of the revised Terms. If you do not agree to the revised Terms, you must uninstall and stop using the Apps.
