Terms of Service — Gemians: Theme Sections

Last updated: 9 November 2026

These terms govern your use of the Shopify app Gemians: Theme Sections ("the app"), provided by Harry Xuan, an individual in Vietnam, who publishes it under the name Gemians ("we"). By installing the app you agree to them.

1. The service

The app lets you add Gemians Product details, a buy box for your product pages, and pre-built page templates to your Shopify store's theme, and remove them again. It also includes a Sticky add to cart app embed, which you can turn on in your theme editor. You set items up yourself, with the steps shown in the app, and our team helps when you need it (section 11).

2. What the app changes in your store

The app only ever writes files named with gemians, into the theme you choose: sections, snippets and assets whose names begin with gemians-, and templates named <page type>.gemians.json or <page type>.gemians-<name>.json. It does not modify your theme's own files, layout, settings or translations. This is enforced by the app's code before any change is sent to Shopify.

Page templates are built from your theme's own existing template at the moment you install them, so your theme's own content — product details, collection grids, blog posts — is kept. The app never changes that existing template: the Gemians template sits next to it, and your pages keep using your own template unless you assign the Gemians one.

You are responsible for keeping a backup of your theme. Shopify lets you duplicate a theme before making changes, and we recommend doing so.

3. Licence to the sections and templates

Each section and template you install through the app is licensed to you for use in the Shopify store it was installed on. The licence is perpetual: it does not end when you uninstall the app, and the files remain yours to use and edit in that store.

You may modify the files for use in that store. You may not:

• use them in any other store, including by copying them into another store's theme;
• resell, redistribute, publish or share them, in original or modified form;
• remove the copyright line at the top of each file.

If you run more than one store, each store needs its own installation.

If you are refunded for an item. Its licence ends on the day of the refund, and the app no longer adds it to your themes. Section 4 says how its files are removed first. The licence for your other items, free ones included, is not affected.

4. Fees and refunds

Fees. The page templates and the Sticky add to cart app embed are free. Gemians Product details is a one-time purchase: you pay once, at the price shown in the app and on Shopify's confirmation page, before you approve it. There is no subscription. A purchase is for the store that made it, and you can use it on any of that store's themes. Charges are billed through Shopify and appear on your Shopify invoice. We never see your payment card details.

When we refund Gemians Product details. It is delivered as files that stay in your theme, so we refund it only when it does not work in your store and we cannot fix it:

• What counts. On a product page made by a product template of your Online Store 2.0 theme, with any discounts and subscription plans set up as the steps in the app describe, Product details cannot be added to your theme, does not show on the page, or does not add the chosen product, variant, subscription plan or quantity to the cart at the price it shows.
• When to tell us. Within 30 days of the first time you add it to a theme, and no later than 45 days after you buy it. Choose Something isn't working in the app's support form, or email us. If you tell us in time, you keep this right while we work on it, even after those dates.
• What we do. We try to fix it, and we may ask to work in your store with you (section 11). If we cannot make it work within 10 business days of having the information and access we need, we refund it. Time spent waiting for your reply, or for you to approve our access, does not count.
• Without you asking. If you told us in time and we still have not made it work by day 80 after your purchase, for a reason on our side, we refund it without you having to ask. We contact you before then, so its files can be removed in time.
• Other apps and themes. A conflict with another app counts only if that app was in your store when you bought Product details. Moving to another theme counts if you tell us within the same 30 days and the new theme is an Online Store 2.0 theme listed as tested on Product details' page in the app.
• What does not count. Sales or conversion results; a change of mind, or not liking how it looks; a feature the app does not describe; a problem caused by changes made to Gemians files or to your theme's code; pages not made by a product template of your theme, such as page-builder or headless pages; trial or vintage themes; and a report we could not finish because we did not hear back from you. We still help with those, and we don't charge for fixes (section 6).
• Before we refund. First stop using it: switch your products back to your previous template, or take it out of any template you placed it in. Then remove its files from your themes with the app. We can do this with you, and we check your themes before we refund. If you can no longer get into your Shopify admin, we refund without waiting for this.
• How. Refunds go through Shopify, for the full amount you paid. We start the refund within 2 business days of our decision and email you when it is done, because Shopify does not notify you of app refunds. The item's licence then ends (section 3). Shopify's charge approval page calls one-time charges non-refundable: that is Shopify's standard wording, and it does not change this section.
• Once per item for each store. If your store buys an item again after a refund for it, that purchase is final, except for a charge made in error.

A charge made in error, for example being charged twice for the same item: tell us within 60 days of the charge and we refund it through Shopify.

This does not limit any right to a refund that you have by law. Free items, and the Sticky add to cart app embed, involve no charge.

5. Uninstalling

When you uninstall the app, Shopify revokes its access to your store immediately, so the app cannot remove its files afterwards. To remove them, use "Remove all Gemians files" in the app before uninstalling. Files left in your theme after uninstall remain there, subject to section 3. If Product details is not working, tell us before you uninstall (section 4): afterwards the app can no longer reach your theme.

We delete your store's access token when you uninstall — see the Privacy Policy.

6. Availability and changes

We may update Product details, the page templates and the app. We don't charge for updates or fixes to an item you have. We never write a newer version over files already in your theme on our own: the app replaces a file only when you ask it to, with Update or Replace template. Update replaces the item's files in that theme, including changes made to them in the code, and asks first when there are such changes; the settings you made in the theme editor stay.

7. Disclaimers

The app, and the sections and templates it installs, are provided "as is" and "as available". Beyond what these terms and the app itself describe, we make no warranties, express or implied, including warranties of merchantability or fitness for a particular purpose. We do not guarantee that the sections and templates work with every theme or alongside every other app, or that the app will be uninterrupted or free of errors. How they look and behave also depends on your theme, your content and your other apps, which we do not control.

8. Limitation of liability

To the extent the law allows, our total liability for any claim arising out of or relating to the app or these terms is limited to the amounts your store paid us in the 12 months before the claim arose. We are not liable for any indirect, incidental, special or consequential damages, or for lost profits, revenue or data, even if we were told they were possible. Nothing in these terms excludes or limits liability that cannot be excluded or limited by law.

9. Termination

You may stop using the app at any time by uninstalling it. We may suspend access for a breach of these terms. Sections 3, 4 (for problems you reported before then), 7 and 8 survive termination.

10. Governing law

These terms are governed by the laws of Vietnam. Any dispute arising out of or relating to them or to the app is subject to the jurisdiction of the courts of Vietnam.

11. Help from our team

You set up each item yourself, with the steps shown in the app, and Check my setup shows what is left to do. If you have a question, or something isn't working, write to us with the support form in the app, or email us.

• Replies. We aim to reply by email within 2 business days (Monday to Friday, Vietnam time).
• Working in your store with you. If you have bought Gemians Product details, done every step in the app, run Check my setup and told us through the support form, and it still does not work, someone from our team can work on it in your store with you, at no extra charge. We aim to start within 3 business days after you approve our access.
• What that covers. Making Product details work as designed on one product template: placing it in the Gemians template, hiding your theme's own product section in that template, placing the blocks of a subscription or review app you already use so that adding to cart works, checking prices in the cart on one product, and looking into any problem with Product details itself. It does not cover choosing a layout or style for you, writing content, setting up discounts, more templates, or changes to your theme's code.
• How it works. We send a collaborator request from our Shopify Partner account. You approve it in your Shopify admin and choose what it can access; we ask for themes and products only, and tell you first if a task needs anything more. You can remove our access at any time, and we ask you to remove it when we are done.
• What we change. Only the Gemians template, in the theme editor, and Gemians files, through the app's own buttons. We never edit your theme's code, its own templates or its settings, and we never publish a theme for you. We assign the Gemians template to a product only if you ask us to. We may add a product to a cart to check its price; we never place orders or enter payment or customer details.
• Who. The app and this help are provided by Harry Xuan, and anyone who helps works for him.

12. Other apps

Product details works with some apps you may use, such as subscription and review apps. Gemians is not affiliated with or endorsed by those apps unless we say so. We name them only so you can see which ones we have tested.

• Tested. When the app says Product details was tested with another app or a theme, we ran a recorded test with it, on the date shown. Apps and themes change. If one stops working with Product details and we learn of it, we work on a fix at no charge (section 6), but we can't promise that every app will keep working with it.
• Their terms apply to them. Other apps' terms, prices and data practices are their own; we don't control them.

13. Changes to these terms

We may change these terms. When we do, we change the date at the top of this page. A change never takes away a refund your store was entitled to when it bought an item, or setup by our team that was included in the item's price when your store bought it.
