Terms of service

Last updated: September 15, 2026

1. Who this agreement is with

These terms are an agreement between Nodiumtech LLC, a Texas limited liability company (“we”, “us”), and the merchant who installs A11y Suite (“you”). By installing the app you accept them. If you are installing on behalf of a company, you confirm you are authorised to bind it.

2. What the service does

A11y Suite:

• opens representative pages of your public storefront in a real browser and tests them against the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA, using the open-source axe-core engine together with our own additional checks;
• records the evidence behind each finding — the failing element, the measurement, a screenshot, and the date;
• tells you which theme setting, Liquid file, or app is responsible, and what to change;
• audits your product images for missing or duplicated alt text and, if you ask it to, drafts replacements for you to approve;
• gives you guided questions for the criteria a machine cannot judge, and assembles the answers into a report you can keep.

It does not add any code to your storefront. The one optional component that reaches your storefront is the Accessibility Fixes app embed, which sends stylesheet rules only, contains no JavaScript, and is off until you switch it on in your theme editor.

3. What the service is not

It is not legal advice. We are not a law firm and no lawyer–client relationship arises from your use of the app. If you have received a demand letter or have been sued, talk to a lawyer.

It is not a compliance guarantee. Automated testing can detect a meaningful share of accessibility problems, but no automated tool can detect all of them, and conformance with WCAG is not the same thing as compliance with any particular law — the Americans with Disabilities Act, Section 508, the European Accessibility Act, EN 301 549, the AODA, or any other. We do not promise that using A11y Suite will prevent a complaint, a demand letter, a lawsuit, a fine, or an enforcement action, and we do not certify your store.

Reports are yours to stand behind. Any accessibility statement or conformance report the app helps you assemble reflects your own answers and the state of your store on the date it was produced. It is not an independent third-party audit, and publishing it is your decision.

4. Your side of it

• Install the app only on a store you own or are authorised to administer. Do not use it to scan a store that is not yours.
• Review anything the app proposes before you publish it. Alt text drafts in particular are suggestions; you are responsible for what ends up on your store.
• Do not attempt to break into, overload, reverse engineer, or resell the service, and do not use it to build a competing product.
• Keep your Shopify account secure. Anyone with staff access to your store can open the app.

5. Permissions and what we write

The app asks for permission to read and write products, and nothing else. It uses the write permission for exactly one thing: saving alt text onto product images after you have approved it. It never edits your products, prices, inventory, theme files, or anything else, and it cannot reach your customers or your orders.

6. Price and billing

• There is a free tier that checks your home page.
• The Pro plan is US$29 every 30 days with a 7-day free trial. It covers all page templates, evidence screenshots, conformance reporting, guided manual checks and monitoring.
• All charges are made through Shopify’s billing system and appear on your Shopify invoice. We never see or hold your card details.
• Charges recur every 30 days until you cancel. Cancel by downgrading in the app or by uninstalling; the change applies from the next billing period.
• Charges already billed are not refunded automatically. If something went wrong, write to us — we would rather sort it out than argue about it.
• If we change the price, we will tell you at least 30 days beforehand, and Shopify will ask you to approve the new charge. You are never billed more without approving it.

7. Who owns what

You own your store data and the reports the app produces for you. You may publish, print, and hand them to anyone. We own the app, its scanning rules, and everything else about the service; nothing here transfers that to you. axe-core is used under the Mozilla Public License 2.0 and remains the property of Deque Systems.

We will not use your store as a public example, name you as a customer, or publish your results without asking you first.

8. Availability

We aim to keep the service running and to scan promptly, but we do not offer a service level agreement. Maintenance, a Shopify API change, or a fault can interrupt it. If we plan downtime that affects you, we will say so in advance.

9. Disclaimer and limit of liability

The service is provided “as is”. To the fullest extent the law allows, we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

Our total liability to you, for everything arising out of this agreement taken together, is limited to the amount you actually paid us in the twelve months before the event giving rise to the claim, or US$100 if that is greater. We are not liable for lost profits, lost revenue, lost data, or indirect, incidental, special or consequential damages, or for the outcome of any accessibility claim, demand, or proceeding brought against you.

Nothing here excludes liability that cannot lawfully be excluded — including for fraud, for wilful misconduct, or any right you have under mandatory local law, which is unaffected by this agreement.

10. Indemnity

You agree to cover us against claims arising from your use of the service in breach of these terms, from content you publish on your store after reviewing our suggestions, and from your scanning a store you were not authorised to scan.

11. Ending it

You may uninstall at any time; that ends the agreement and stops future charges. We may suspend or end the agreement if you break these terms, if we are required to by law, or if we discontinue the service — in which case we will give you at least 30 days’ notice and will not charge you for a period you cannot use. On termination we delete your data as described in the privacy policy.

12. Changes

We may update these terms. We will change the date at the top, and for material changes we will notify you in the app or by email before they take effect. Continuing to use the service after that means you accept the new terms.

13. Governing law

These terms are governed by the laws of the State of Texas, United States, without regard to its conflict of laws rules, and the state and federal courts in Harris County, Texas have jurisdiction. If you are in the European Economic Area or the United Kingdom, this does not deprive you of the protection of mandatory provisions of the law of your own country.
