AS: Upsell & Cross Sell

Terms of Use

for the AS Upsell & Cross Sell app by Augmentum Studios Ltd, available on Shopify App store

Last updated: 9 February 2026

1. Introduction

These Terms of Use (the “Terms”) govern your access to and use of the AS: Upsell & Cross Sell Shopify app (the “App”) provided by Augmentum Studios Ltd, a company established in the United Kingdom (“Augmentum Studios”, “we”, “us”, or “our”).

By installing or using the App in connection with your Shopify store, you (“you”, “your”, or the “Merchant”) agree to be bound by these Terms. If you do not agree to these Terms, do not install or use the App.

2. Who we are

Company: Augmentum Studios Ltd
Email: support@augmentumstudios.com
Postal address: Augmentum Studios Ltd, International House, 101 King’s Cross Road, London, United Kingdom WC1X 9LP
Jurisdiction: United Kingdom

You acknowledge that you are entering into these Terms with Augmentum Studios Ltd, not with Shopify Inc. or any of its affiliates.

3. Relationship with Shopify

The App is made available through the Shopify App Store and integrates with the Shopify platform. Your use of Shopify itself is governed by Shopify’s own terms of service and policies, which are separate from these Terms.

We are not responsible for Shopify’s platform, services, availability, pricing, or policies.
Any issues relating to your Shopify account, billing by Shopify (outside of App fees), or Shopify’s own features must be resolved directly with Shopify.

4. Description of the App

The App is an Upsell & Cross-sell Widget that:

Allows you to configure offers via an Admin UI within your Shopify dashboard;
Supports offers on the following storefront surfaces (depending on your theme and configuration):
- Product page (e.g., add-ons, cross-sells);
- Cart page; and
- Cart drawer;
May offer multiple offer UI controls (for example checkbox, toggle, or button-style add-ons), subject to your configuration and theme capabilities;
Supports offer conditions and triggers (for example, rules based on the cart or product context), subject to your configuration;
Provides offer performance analytics and reporting (for example, impressions, add-to-carts, purchases, and attributed revenue) and may support translations/localization where enabled;
Provides configuration options for appearance and styling, including no-code styling options and, where enabled, custom CSS;
Uses Shopify APIs and certain permissions (including read_orders, read_products, write_products, read_themes, and locales access) to display offers, add line item properties, provide translations/localization where enabled, and provide aggregated analytics (views, add-to-carts, purchases, attributed revenue).

Because the App depends on Shopify’s APIs, theme configuration, and your store setup, its exact behavior may vary between merchants.

5. Eligibility and merchant responsibilities

By installing or using the App, you represent and warrant that:

You are at least 18 years old and have the legal capacity to enter into binding contracts;
You are using the App for business purposes (not as a consumer);
You have full authority to bind the business or organization on whose behalf you use the App;
Your use of the App will comply with:
- All applicable laws and regulations (including data protection, consumer protection, and e-commerce laws); and
- All applicable Shopify policies and terms.

You are solely responsible for:

The operation and content of your Shopify store;
The legality and accuracy of your offers (including upsells, cross-sells, add-ons) and pricing;
Properly informing your customers about any additional products, fees, or conditions;
Ensuring that your store’s privacy policy and terms reflect your use of the App where required.

6. Account, installation, and access

To use the App:

You must have an active Shopify store and Shopify account.
You must install the App from the Shopify App Store and grant the requested permissions.
You must complete the App setup steps, which typically include:
- Selecting a plan (if applicable, after any free trial period);
- Adding the App Block and/or enabling the App Embed in your theme on supported surfaces (Product Page, Cart Page, and/or Cart Drawer);
- Creating at least one offer configuration.

You are responsible for ensuring that:

Only authorized staff have access to your Shopify admin and App configuration;
Any login credentials or API tokens related to your store are kept secure;
You uninstall the App if you no longer wish to use it or do not agree with future updates to these Terms.

7. Permissions and data access

By installing and using the App, you authorize us to access and process certain data from your Shopify store via Shopify’s APIs, including:

read_orders – to identify orders that contain offer-attributed items and attribute aggregated revenue to specific offers;
read_products and write_products – to allow you to configure offers and to add line item properties to distinguish offer-originated items in the cart;
read_themes – to determine the installation status of the App Block in your theme and provide related feedback in the Admin UI;
Locales access – to provide translations/localization where enabled.

We use these permissions only as necessary to provide the App’s core functionality and associated analytics, as described in our Privacy Policy.

For details on how we collect, use, and protect data, please refer to our Privacy Policy (https://augmentumstudios.com/products/as-checkbox-upsell/privacy-policy/), which is incorporated into these Terms by reference.

8. Subscription, billing, and fees

8.1 Pricing and billing

The App is offered via Shopify Billing and may include recurring and usage-based charges, billed every 30 days, as presented to you by Shopify at the time you approve the charge.
All charges are billed in USD.
The App’s then-current pricing, including any free trial, plan features, eligibility requirements, and any applicable usage limits or usage-based charges, is described in the Shopify charge approval flow and/or on the App’s Shopify App Store listing.
If a plan includes usage limits or usage-based charges, those limits/charges may be determined based on the App’s attribution and analytics (for example, purchases that include items added via the App’s offers), as described in the App Admin UI and/or the App Store listing.

For usage-based pricing and revenue attribution reporting, the App may need to normalize order amounts into a single currency (USD). Shopify orders typically provide the shop’s currency (the store’s default currency) and the presentment currency (the currency the shopper paid in), but do not provide all exchange rates needed for consistent normalization across currencies.

To perform this normalization, we retrieve USD exchange rates from Open Exchange Rates (https://openexchangerates.org/) and refresh them hourly. We use the latest available exchange rate at the time of attribution. We do not guarantee that exchange rates will be refreshed without interruption at all times; if a rate refresh fails, we reserve the right to use the last available exchange rate we have stored in our database records, and we will use reasonable efforts to detect issues and restore hourly refresh so that the latest rates are used.

All billing, invoicing, and payment processing for the App is handled by Shopify under your agreement with them. We do not directly process your payment card details.

8.2 Changes to fees

We may change the App’s pricing or subscription structure in the future. If we do:

Changes will generally take effect at the start of your next billing period; and
You will be notified through the Shopify App Store listing and/or within the App Admin UI, or by another reasonable method.

If you do not agree to the new fees, you must uninstall the App and/or cancel your subscription before the new fees apply.

8.3 Refunds

Unless required by law or Shopify’s policies, fees are non-refundable. Any refund requests must be handled through Shopify according to their billing policies.

9. Data protection and privacy

Your use of the App is also governed by:

Our Privacy Policy (https://augmentumstudios.com/products/as-checkbox-upsell/privacy-policy/), which describes how we collect, use, and protect data, including store and customer data accessed via Shopify.

By using the App, you:

Acknowledge that you have read and understood the Privacy Policy; and
Agree that it forms part of these Terms.
Confirm that you have provided appropriate notices and obtained any necessary consents from your customers for the use of the App and processing of personal data in connection with your store.

You remain the controller of your customers’ personal data. We act as processor where we process such data on your behalf through the App.

10. Intellectual property

The App, including all software, code, design, documentation, and content provided by us, is and remains the exclusive property of Augmentum Studios Ltd (and its licensors, if any).

Subject to your compliance with these Terms and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, revocable license to use the App for the sole purpose of operating your Shopify store’s upsell and cross-sell functionality on supported surfaces (including product page, cart page, and cart drawer).

You may not:

Copy, modify, adapt, or create derivative works of the App (except as expressly permitted by mandatory law);
Reverse engineer, decompile, or attempt to extract the source code of the App, except where allowed by law and only to the extent explicitly permitted;
Remove or alter any proprietary notices or trademarks on the App;
Use the App to build a competing product or service.

11. Acceptable use

You agree not to use the App in any way that:

Violates any applicable law or regulation;
Is false, misleading, fraudulent, or deceptive (e.g., misleading upsell offers, hidden fees);
Infringes or misappropriates any third party’s intellectual property, privacy, or other rights;
Involves sending spam or other unauthorized communications;
Introduces viruses, malware, or other harmful code;
Interferes with or disrupts the integrity or performance of the App, Shopify, or other merchants’ stores.

We reserve the right (but have no obligation) to suspend or terminate your access to the App if we reasonably believe that your use violates these Terms, applicable law, or poses a security or reputational risk.

12. Availability, changes, and updates

We aim to keep the App available and functioning, but:

The App is provided via third-party infrastructure (including Shopify, Vercel, and NeonDB), which may experience downtime or changes;
We may update, modify, or discontinue parts of the App at any time (including features, user interface, and technical implementation) to improve performance, security, or to comply with Shopify’s or legal requirements.

Where reasonably possible, we will avoid changes that materially degrade the core upsell functionality without notice. However, we do not guarantee uninterrupted operation or that the App will remain unchanged over time.

13. Support

We may provide support for the App via email or other channels as indicated in the App listing or documentation.

Support is provided on a reasonable efforts basis and is not guaranteed to be available at all times.
Response and resolution times are not guaranteed unless expressly agreed in writing.

14. Disclaimers

To the maximum extent permitted by law, the App is provided on an “as is” and “as available” basis, without warranties of any kind, whether express, implied, or statutory. We specifically disclaim any implied warranties of:

Merchantability;
Fitness for a particular purpose;
Non-infringement;
Accuracy, reliability, or completeness;
Compatibility with your theme, other apps, or your specific configuration.

You are solely responsible for testing the App in your store (including upsell logic, pricing, and checkout flows) before relying on it in a production environment.

We do not warrant that:

The App will be error-free, uninterrupted, or free from security vulnerabilities;
The App will always function with all themes, other apps, or third-party services;
The App will result in a particular level of sales, revenue, or performance improvement.

15. Limitation of liability

To the maximum extent permitted by law:

Exclusion of certain damages
We will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, business, data, or goodwill, arising out of or in connection with your use of or inability to use the App, even if we have been advised of the possibility of such damages.
Cap on liability
Our total aggregate liability to you for all claims arising out of or relating to the App or these Terms shall not exceed the greater of:
- The total amount of App fees (including recurring and usage-based fees) you paid to us via Shopify for the App in the preceding three (3) months; or
- USD 50.

Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law (for example, liability for death or personal injury caused by negligence, or for fraud).

16. Indemnification

You agree to indemnify, defend, and hold harmless Augmentum Studios Ltd and its directors, officers, employees, and agents from and against any and all claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in connection with:

Your use of the App;
Your store’s operations, content, products, or services;
Your violation of these Terms or applicable law;
Any claim that your store or its use of the App infringes or violates any third party rights.

17. Term, termination, and uninstallation

These Terms apply from the time you install the App until:

You uninstall the App from your Shopify store; or
We terminate your access in accordance with these Terms.

You may uninstall the App at any time via your Shopify admin panel. Uninstallation will typically stop future billing for the App (subject to Shopify’s billing cycle and policies).

We may suspend or terminate your access to the App (in whole or in part) if:

You breach these Terms or applicable law;
We reasonably believe your use poses a security, legal, or reputational risk;
We decide to discontinue the App entirely.

Upon termination or uninstallation:

Your license to use the App immediately ends;
We may retain, delete, or anonymize data in accordance with our Privacy Policy and applicable law;
Certain provisions of these Terms that by their nature should survive (e.g., intellectual property, disclaimers, limitation of liability, indemnity, governing law) will continue to apply.

18. Changes to these Terms

We may update or modify these Terms from time to time, for example to:

Reflect changes in the App or our business;
Comply with changes in Shopify’s requirements;
Address changes in applicable laws or regulations.

When we make material changes, we will take reasonable steps to notify you, such as:

Updating the “Last updated” date at the top of these Terms;
Displaying a notice within the App Admin UI; or
Using another reasonable method.

If you continue to use the App after the updated Terms become effective, you are deemed to have accepted the changes. If you do not agree, you must uninstall the App and stop using it.

19. Governing law and jurisdiction

These Terms, and any dispute or claim arising out of or in connection with them or their subject matter or formation (including non-contractual disputes or claims), shall be governed by and construed in accordance with the laws of England and Wales.

You and we agree that the courts of England and Wales shall have exclusive jurisdiction to settle any such dispute or claim, subject to any mandatory consumer or other protections that may apply (if applicable).

20. Miscellaneous

Severability: If any provision of these Terms is found invalid or unenforceable, the remaining provisions will remain in full force and effect.
No waiver: Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision.
Assignment: You may not assign or transfer your rights or obligations under these Terms without our prior written consent. We may assign or transfer our rights and obligations, for example in connection with a merger, acquisition, or sale of the App or our business.
