Install on ShopifyThemes and compatibility.
Does Modulo work with my theme?
Yes, if you're on an Online Store 2.0 theme — Dawn, Symmetry, Debut, Sense, Refresh, and most modern paid themes qualify. Modulo registers theme sections and app blocks the same way Shopify's own sections do, so they appear alongside your theme's native sections in the editor.
What about vintage (non-2.0) themes?
Vintage themes don't support theme app extensions, so Modulo sections won't appear in the editor. If you're on a vintage theme, the easiest path is to update to a 2.0 theme — most paid themes have a free 2.0 version available from the same maker.
Will it work on a custom-built theme?
Yes, as long as the theme exposes the Online Store 2.0 section framework. If your developer built a custom theme on top of Dawn or uses standard JSON templates, Modulo will work without changes. If you're unsure, install Modulo on a duplicated theme first.
Install and setup.
How do I install Modulo?
Install from the Shopify App Store with one click. Modulo registers its sections and blocks with your active theme on install — no theme code edits, no manual setup. Open the theme editor and the sections appear under Add section.
Do I need to edit my theme code?
No. Everything Modulo does runs as theme app extensions — the modern, sandboxed format Shopify built specifically so apps don't modify theme.liquid or inject scripts into the head. Your theme files stay untouched.
Should I install on my live theme or a copy first?
Always test on a duplicated theme first, the same way you'd test any change. Duplicate your live theme in Shopify admin, preview Modulo sections on the duplicate, then publish when you're happy.
Sections and the theme editor.
What kinds of sections are included?
36 native theme sections covering the page types most merchants need: hero, features, FAQ, testimonials, image+text, social gallery, product carousel, comparison table, editorial story, video, logo cloud, press quotes, and more. Use them on landing pages, product pages, the home page, collection pages, and any other 2.0 template.
Can I edit copy and images inline in the theme editor?
Yes. Every section exposes its content as theme editor settings — you edit headings, body copy, images, and links the same way you edit your theme's built-in sections. No separate page builder UI to learn.
Are the sections responsive?
Every section is built mobile-first and tuned for the breakpoints of the themes most merchants run. You can preview on desktop, tablet, and phone in the theme editor before publishing.
Do you take custom section requests?
Yes. If you need a section we haven't built, email me. If the request is reusable across other stores, we'll build it free and add it to the library.
Bundles, discounts, free gifts.
How do bundles apply at checkout?
Bundles use Shopify's native automatic discount engine. When a customer adds qualifying items to the cart, the discount applies automatically — no codes for the customer to enter, no scripts interfering with checkout, no extra checkout fees from third-party payment routing.
What kinds of bundles can I run?
Tiered volume bundles (buy 2 save 10%, buy 3 save 20%), fixed-set bundles (product A + product B for one price), and mix-and-match bundles across a collection. Each bundle supports a free-gift inheritance rule.
How do free gifts work?
Configure a free-gift rule alongside a bundle and the gift inherits the bundle's qualifying conditions. The gift line is added at zero cost when the cart meets the threshold. Inventory for the gift is tracked normally — Modulo won't add a gift if it's out of stock.
Will bundle discounts stack with my other discount codes?
Modulo follows Shopify's native discount stacking rules. If you've enabled Combine with other discounts in your discount settings, bundle discounts will stack with eligible order-level or shipping discounts. Otherwise the best applicable discount wins, as Shopify decides.
Where does the bundle widget render on my product page?
Modulo ships a storefront block that you drop into the product template from the theme editor, typically just above or below the add-to-cart button. You choose the placement; Modulo just provides the block.
Storefront blocks.
What storefront blocks are included?
16 conversion blocks: trust badges, sticky add-to-cart, payment icon row, stock urgency, FAQ accordion, sale countdown, shipping-threshold meter, recently-viewed products, gift-wrap opt-in, size-guide modal, and more. Each is a theme app block you add from the theme editor.
Are the urgency and stock blocks real or fake?
Real. The stock-urgency block reads Shopify's actual inventory and only renders when stock is genuinely low against the threshold you set. We don't ship fake counters, fake purchase notifications, or anything that fabricates social proof. Shopify disallows it and it's bad business besides.
Performance and theme code.
Will Modulo slow down my store?
Modulo sections render natively inside your theme — server-side Liquid, not iframes, not client-side hydration of a separate app shell. There's no app proxy redirect, no third-party script injected into your head, and no checkout.liquid modification. The app is built to keep storefront pages fast on the themes most merchants use.
Do you inject scripts into my theme's head?
No. Everything runs through theme app extensions, which Shopify isolates from theme.liquid. The app admin uses App Bridge inside the Shopify admin iframe; the storefront integration is plain Liquid that Shopify renders.
Does Modulo modify checkout.liquid?
No. checkout.liquid is deprecated by Shopify and we don't touch it. Checkout-page customizations, where offered, run as checkout extensions on Shopify Plus.
Data, privacy, and GDPR.
What data does Modulo collect?
The minimum needed to do its job. Admin authentication via Shopify App Bridge (session token only, no persistent identifier). Storefront analytics events via Shopify's Web Pixels API, gated by the Customer Privacy API — so if a shopper hasn't consented to analytics, we don't collect. No fingerprinting, no cross-store tracking, no shopper profiles sold to anyone.
Is Modulo GDPR-compliant?
Yes. We handle the three mandatory GDPR webhooks Shopify requires:customers/data_request, customers/redact, and shop/redact. Read the full privacy policy for what we store, how long, and how to request deletion.
Do you sell or share merchant data?
No. Modulo data stays inside Modulo. We don't sell to data brokers, we don't share with ad networks, and we don't feed shopper events into third-party retargeting platforms.
Checkout and upsells.
Can Modulo run upsells in checkout?
On Shopify Plus, yes — through Shopify's checkout extensions. One-click upsells are presented with explicit opt-in copy and a clear price, and the buyer must accept the charge before the additional item is added to the order. No silent additions.
Do post-purchase upsells stack?
Shopify limits post-purchase offers to one per order, and Modulo obeys that cap. If multiple upsell rules match an order, Modulo picks the highest-value relevant offer and shows it once.
Pricing and plans.
How much does Modulo cost?
Modulo is free at launch. Every section, every block, the full bundling engine — no tiers, no per-feature paywalls. See the pricing page for the full plan.
Will pricing stay free forever?
A paid tier may arrive once Modulo is Built-for-Shopify certified. Stores that install before then are grandfathered onto the free plan permanently. That's a public commitment in the terms, not a marketing line.
Are there transaction fees or revenue share?
No. Modulo doesn't take a cut of bundle revenue, doesn't mark up shipping, doesn't skim checkout. Bundles go through Shopify's native discount engine and the money flows the same way it always did.
Support.
How do I get support?
Email hello@runmodulo.com. The reply comes from the founder, usually within four hours during EU working hours. No chatbot, no triage layer, no outsourced agents.
Is there documentation or a help center?
Setup help lives inside the app admin — each section and bundle type has inline guidance where you configure it. Email support for anything not covered in-app; if a question comes up twice, it becomes a help-center article.
Uninstall.
Can I remove Modulo without breaking my theme?
Yes. Sections and blocks are theme-scoped — uninstalling the app removes the Modulo options from the editor, and any active Modulo sections fall back to your theme's default layout. No orphaned Liquid, no script tags left behind in your theme.
What happens to active bundles when I uninstall?
Automatic discounts created by Modulo are deactivated on uninstall. Past orders that used a bundle discount remain intact — the historical record doesn't change.
Will my data be deleted?
Yes. On uninstall Shopify sends the shop/redact webhook 48 hours later. Modulo deletes all shop-scoped data within 30 days, as required. See the privacy policy for the schedule.
Still stuck?
Email hello@runmodulo.com. The reply comes from me, usually within four hours during EU working hours. If your question turns into something other merchants will hit too, it gets added to this page.
