Terms of Service

Last updated 26 September 2026

These terms apply to the Store Diagnosis app for Shopify ("the app"), provided by Mufatech ("we", "us"). By installing or using the app on a Shopify store, you ("you", the merchant) accept these terms on behalf of the business that owns the store. Shopify's own terms continue to apply between you and Shopify.

1. What the app does

The app reads your store's products, stock and orders through Shopify, with read-only access, and shows where money is tied up or lost: stock that is not selling, best-sellers running out, discounts and refunds that cost margin, and profit by product. It can also send a weekly summary email to your store's contact email. It never changes anything in your store.

2. Price

The app is free. If we ever offer paid features, we will say so in the app beforehand, and nothing is charged unless you approve it through Shopify's billing.

3. The figures are estimates, and the decisions are yours

The app's findings are calculated from the data in your store, including the cost per item you entered. Missing or wrong costs, stock counts or order data give less accurate results; the app shows where it had to estimate. The findings are information to help you decide. They are not financial, accounting, tax or legal advice, and you remain responsible for every price, discount, order or other decision you make in your store.

4. Fair use

You agree not to:

use the app for any store you are not authorised to manage;
try to access other merchants' data, our servers or our code beyond what the app offers you;
copy, resell, or reverse-engineer the app, or build a competing service from it;
overload the app, for example by automated requests, or disrupt it for others;
use the app in breach of the law or of Shopify's terms.

5. Your data

Your store's data stays yours. We use it only to provide the app to you, as described in the privacy policy and the Data Processing Addendum, which form part of these terms. We do not sell it, use it for advertising, or combine it with other merchants' data.

6. Our rights

The app, its code, design, texts and the methods behind its findings belong to Mufatech. While the app is installed, you may use it and the reports it produces for your own business, including sharing them with your staff and advisers.

7. Availability and changes

We work to keep the app running and correct, but we do not promise it will be uninterrupted or free of errors. We may improve, change or remove features. If we decide to shut the app down, we will tell you in the app and by email at least 30 days before.

8. No warranties

To the extent the law allows, the app is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose, merchantability and non-infringement.

9. Limitation of liability

To the extent the law allows:

we are not liable for indirect or consequential losses, lost profits, lost revenue, lost sales or lost data, or for decisions you make based on the app's findings;
our total liability arising from the app or these terms is limited to the greater of the fees you paid us for the app in the 12 months before the claim, and 100 US dollars.

Nothing in these terms limits liability that cannot be limited by law, such as liability for fraud or for death or personal injury caused by negligence.

10. Ending

You can stop at any time by uninstalling the app. We may suspend or end your access if you break these terms, if Shopify requires it, or if we shut the app down under section 7. What happens to your data when you uninstall is set out in the Data Processing Addendum: it is erased 48 hours after uninstalling. Sections 3, 6, 8 and 9 continue to apply after the end.

11. Changes to these terms

We may update these terms. We will announce material changes in the app and on this page at least 30 days before they apply. If you keep using the app after that, the new terms apply; if you do not agree, you can uninstall it.
