Stop Overpaying

Terms of service

Last updated: August 21, 2026

These Terms of Service (“Terms”) govern a merchant’s use of the Stop Overpaying Shopify application, its Back in Stock module, and related support services (collectively, the “Service”). By installing the app, enabling a module, or using the Service, the merchant agrees to these Terms on behalf of the business operating the Shopify store.

1. The Service

Stop Overpaying provides optional Shopify commerce modules. The initial module helps merchants collect back-in-stock requests, confirm shopper email addresses, evaluate inventory conditions, send authorized availability notices, and report bounded operational and attributed-revenue information. Features can be added, changed, paused, or removed as the Service evolves. A module remains disabled until the merchant enables it and all applicable readiness controls permit it to operate.

2. Pilot availability and pricing

The controlled Back in Stock pilot is provided without a Shopify billing charge unless Stop Overpaying and the merchant agree otherwise in writing. We may set reasonable pilot eligibility, support, volume, or feature limits. We will not introduce a paid recurring charge for a merchant without the merchant’s affirmative agreement through the applicable Shopify billing flow, where required.

3. Merchant responsibilities

The merchant is responsible for:

  • maintaining a valid Shopify store and all permissions needed to use the Service;
  • providing truthful product, inventory, branding, and configuration information;
  • obtaining and maintaining any notices, permissions, and consent required for the merchant’s products, storefront, and messages;
  • using the Service only for legitimate goods, services, and customer communications; and
  • promptly investigating configuration issues and keeping an authorized merchant contact available.

The merchant must not use the Service to send deceptive, unlawful, discriminatory, abusive, or unsolicited communications; to collect credentials or sensitive data outside the stated module flow; or to bypass Shopify, email-provider, privacy, or consumer-protection requirements.

4. Shopify and third-party services

The Service integrates with Shopify and, for enabled email modules, Postmark. The merchant’s use of those platforms is governed by the merchant’s separate agreements with them. Shopify controls the store, products, checkout, and platform access. Stop Overpaying does not alter Shopify checkout or take possession of a merchant’s funds. Provider outages, policy changes, delays, suppression decisions, or platform restrictions can affect the Service.

5. Email and shopper controls

Back in Stock uses a confirmation flow before an email address becomes eligible for alerts. Availability notifications are subject to live authorization checks, merchant settings, inventory evidence, consent, suppression, and provider outcomes. An unsubscribe, bounce, complaint, or safety control can stop an alert even where inventory is available. The merchant must not attempt to defeat or circumvent those controls.

6. Privacy and data

Our processing of merchant and shopper information is described in the Privacy Policy. In relation to shopper information that a merchant provides through Shopify or the Service, the merchant is generally responsible for its customer relationship and notices. Stop Overpaying processes that information to operate the requested module, comply with Shopify privacy events, protect the Service, and meet legal obligations.

7. Intellectual property and feedback

Stop Overpaying retains all rights in the Service, its software, documentation, and branding. Subject to these Terms, the merchant receives a limited, revocable, non-transferable right to use the Service for its own Shopify store. The merchant retains rights in its products, storefront content, and lawful merchant data. If the merchant provides feedback, Stop Overpaying may use it without restriction or compensation.

8. Suspension and termination

A merchant may uninstall the app or pause an enabled module. We may suspend or limit the Service where necessary to protect shoppers, merchants, the platform, or the Service; to address suspected abuse or legal risk; or where a provider or Shopify requires it. Following uninstall or a relevant privacy request, we process the applicable lifecycle event under our Privacy Policy and operational retention obligations.

9. Disclaimers

The Service is provided on an “as is” and “as available” basis to the maximum extent permitted by law. We do not guarantee that an alert will be delivered, opened, clicked, converted, or attributable to a sale; that inventory or third-party data will always be current; or that the Service will be uninterrupted or error-free. Stop Overpaying is not legal, privacy, tax, email-compliance, or business advice.

10. Limitation of liability

To the maximum extent permitted by law, Stop Overpaying and its suppliers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, goodwill, data, or business opportunity arising from the Service. Where liability cannot be excluded, our aggregate liability for a claim is limited to the amount the merchant paid to Stop Overpaying for the affected Service in the twelve months before the event giving rise to the claim.

11. Changes to these Terms

We may update these Terms as the Service and applicable requirements evolve. Material changes will be posted here with an updated date. Continued use after the effective date means the merchant accepts the updated Terms. If the merchant does not agree, it should stop using the Service and uninstall the app.
