How do I install the theme?
Download the package from My licenses and install it in Extensions > Installer, then Extensions > Themes, like any other OpenCart theme. The Documentation tab has every step, from the first activation to the theme settings.
Which OpenCart versions does it work with?
OpenCart 4.0.2.0 – 4.1.0.4, 3.0.x. Every release is installed and tested on OpenCart 4.1.0.4 and OpenCart 3.0.5.1 before it is published. The Compatibility tab lists every version range.
Do I get packages for OpenCart 4 and OpenCart 3?
Yes. Every download has a package for OpenCart 4.0.2 to 4.1.x and one for OpenCart 3.0.3 to 3.0.5, and the license key works with both. Moving from OpenCart 3 to 4 later costs nothing.
What does the license cover?
One production store domain with every subdomain (www, shop., staging.), plus local development hosts such as localhost, *.local and *.test. A store on another domain needs its own license; a second-store license is 40% off. You have 14 days after installing to enter the key. 12 months of updates and support are included; after that the theme keeps working and renewals are 50% off. How licensing works
Can I get a refund?
Yes. Ask for a full refund within 30 days of your first purchase, no reason needed: open a ticket or write to [email protected] with your order number. The money goes back to the card or bank account you paid with within 5 business days of approval. Refund policy
How do I get help?
Open a ticket from your account, so your license details are attached. We answer Monday to Friday: bug reports within 1 business day, how-to questions within 2. Support policy. Not a customer yet? Ask a pre-sales question.
Pulse is the campaign theme of Kavio Labs for OpenCart 4.x and 3.0.x, the OpenCart edition of the Pulse theme for CS-Cart. It makes a store feel like a sale is always on: a flash bar with the sale that ends first, a bento hero with a live deal tile, a dark flash deals zone, discount stickers, promo cells inside product grids, a story player, a Discover feed, a campaign strip on the product page and a sticky buy bar on phones. It fits stores that sell through flash sales, deals of the day, weekend drops and seasonal offers, in electronics, fashion, home, toys or beauty alike.
Every countdown runs to the real end date of an OpenCart special price. Without a running sale the timers are simply not shown.
Pulse home page, Berry scheme
What you get

Installation
OpenCart 4.x
Go to Extensions > Installer and upload kv_theme_pulse.ocmod.zip. Click Install (the green + button) next to it.
Go to Extensions > Extensions, choose the type Themes, and click Install next to Pulse Theme by Kavio Labs.
Click Edit, check that Status is on, pick a Colour scheme and save.
Go to System > Settings, edit your store, and on the General tab set Theme to Pulse Theme by Kavio Labs. Save.
OpenCart 4 has no theme folders. Pulse is a theme extension: it swaps in its own templates while it is the store theme and switched on. Switch the store back to Default to return to the stock look at any time.
Recommended image sizes (System > Settings > Image): product card 600 x 600, product page 1000 x 1000, popup 1400 x 1400, additional 160 x 160, cart 140 x 140, category 600 x 600. Square product images on a white or transparent background look best.
OpenCart 3.0.x
Go to Extensions > Installer and upload kv_theme_pulse-oc3.ocmod.zip.
Go to Extensions > Modifications and click Refresh (the blue button).
Go to Extensions > Extensions, choose Themes, click Install next to Pulse Theme by Kavio Labs, then Edit, check Status, pick a colour scheme and save.
Go to System > Settings, edit your store, open the General tab and set Theme to Pulse Theme by Kavio Labs. Save.
On OpenCart 3 the image sizes and the number of products per page for the theme are on the Listing & images tab of the theme settings.
The demo store
On a fresh store (no products, or only the OpenCart sample products and no orders) the install adds the Brightloop demo: eight departments, 39 illustrated products, specials with end dates, banners, stories and articles, so every section is filled at once. A store with its own catalogue stays exactly as it is.
The Design tab of the theme settings has the buttons:
Install the demo adds it on any store, next to your own products.
Remove the demo deletes exactly what the demo added and restores the theme settings it changed. Your own products stay.
The demo specials run for a few days after the import, so timers on a demo store end. To see them again, remove and add the demo, or give the products new end dates.
Set up your store in six steps
Look. On the Design tab pick a colour scheme, then (optional) your own colours. Without a logo image the header shows a mark with your store name.
Categories. Categories with Show in top menu form the pill bar (OpenCart 3: Top). On Flash bar & menu you can give a pill a shorter name, an icon and a banner.
Sales. Add special prices with an end date (Catalog > Products > Special). The flash bar, deal tile, flash deals zone, card pills and the campaign strip pick them up on their own. Specials without an end date stay on sale but never show a timer.
Hero. On the Home page tab add slides (a scene image, label, title, text, buttons, sticker and an optional countdown), choose the deal product or leave it automatic, and fill the two promo tiles.
Grids. On the Category pages tab add promo cells: where they show (Discover feed or category ids), the place in the grid, one or two cells wide, and the type (promo, video, article), with an optional countdown.
Product data. Pulse reads your normal catalogue data:
Options: radio, select or image options named Colour or Color show as colour dots on cards and as colour chips on the product page. Options listed under Chip option names show as chips with the price change.
Description: the first bullet points (an HTML list) become the highlights.
Special prices with an end date within 60 days give countdowns on cards and on the product page.
Second image: the first additional image of a product appears when the pointer is over the card.
Manufacturers fill the brand line on cards, the brand strip and the brand pages.
Related Products fill Buy together.
Attributes (names are settings): delivery time (Ships in 1-2 days becomes dates on the page), your own label, and a video link.
Filters: add filter groups (Catalog > Filters), assign them to products and categories, and put the core Filter module in the left column of the Category layout (Design > Layouts).
Update
Upload the new package the same way (and refresh modifications on OpenCart 3). Your settings are kept in the store settings.
Uninstall
Switch the store theme back to Default, then uninstall Pulse from Extensions > Extensions > Themes. The theme settings and the demo store are removed; your own catalogue is untouched.
Configuration
Open Extensions > Extensions > Themes > Pulse > Edit. Every storefront text you can change is on one of these tabs. A section that is switched off or has no content is not shown. Settings are per store.

FAQ
Who is Pulse for?
Stores that sell through campaigns: flash sales, deals of the day, weekend drops and seasonal offers. The demo is an electronics store, but the design fits fashion, home, toys, beauty and mixed catalogues alike.
Is it the same Pulse as on CS-Cart?
Yes. Pulse for OpenCart has the same design, colour schemes and Brightloop demo as the Pulse theme for CS-Cart and Multi-Vendor, built natively for OpenCart (Twig templates, OpenCart events, Bootstrap 5 on OpenCart 4 and Bootstrap 3 on OpenCart 3).
How is Pulse different from Atlas?
Atlas is built around finding things in a large catalogue: a department list, a big search and department colours. Pulse is built around running offers: a flash bar, a deal tile, a flash deals zone and countdowns on every page.
How do countdowns work?
Every timer reads the end date of a real special price. The flash bar runs to the special that ends first, the deal tile and the campaign strip to the special of their product, and the flash deals zone to the soonest end among its products. A special without an end date never shows a timer, and no timer restarts on its own. Turn Deal countdowns off to hide them on cards and product pages.
What happens when no sale is running?
Without specials the flash bar shows your message or disappears, the deal tile and the flash deals zone leave the page, and the bento hero closes the gap.
Does Pulse import a demo store?
On a fresh store, yes: the Brightloop demo arrives with the theme. A store with its own catalogue stays as it is and gets a button on the Design tab. The demo is fictional and uses our own illustrations of invented brands.
Can I remove the demo?
Yes, with one click on the Design tab. It deletes exactly what the demo added. Your own products stay. Uninstalling Pulse removes the demo too.
Can I change the colour scheme later?
Yes, any time. A scheme changes the look only. Your products, categories, texts and images stay as they are.
Will my own colours stay readable?
Yes. Pulse picks white or dark text for every coloured surface by contrast and darkens link colours until they reach a contrast of 4.5:1 on their ground.
How do promo cells in the grid work?
You add them on the Category pages tab. Each cell takes a place in the Discover feed or in the product grid of the categories you choose, one or two cells wide. Countdown cells need an end date and disappear after it.
Where do the stories go?
Story circles open a 9:16 player with progress bars and a button to the page you choose. On phones a tap on the left or right side moves between stories.
Can I hide a home section on phones?
Yes. Every section has a Show on setting: all devices, wide screens only, or phones only.
Does Show more work with search engines?
Yes. The page numbers stay under the button as normal links; the button and scroll loading only add the next page to the grid.
Does it slow my store down?
Pulse adds one stylesheet, one script and two self-hosted fonts. Images below the first screen load lazily.
Does Pulse change core files?
No. It uses OpenCart events only (no core changes, no OCMOD). Uninstalling it leaves your store and catalogue as they were.
Server-side tracking for OpenCart 4.x and 3.0.x: purchases, refunds, add to cart, checkout, product views and leads go from your server to the free official GA4 Measurement Protocol, Meta Conversions API and TikTok Events API, deduplicated with the browser pixels through shared event ids. Consent-aware, SHA-256 hashed customer data, order status mapping, queue with retries, test mode and an event log. No paid relay, events only, no OCMOD.
The department store theme for OpenCart 4.x and 3.0.x: colour-coded departments, a department list beside the hero slider with two side promos, a big search with a department selector, tabbed product blocks, a 2 + 1 + 2 offer grid, deals of the day with real countdowns, a department showcase, a promotions band and a three-column product page with a sticky buy box. Four styles (Meridian, Harbor, Citrus, Night) and your own colours on top. Events only, no core changes.
Stop AI crawlers, scrapers, vulnerability scanners and unwanted countries before OpenCart 4.x or 3.0.x builds a page. Googlebot and Bingbot are verified by DNS and always allowed; 50+ bots get one switch each; country rules use free GeoIP databases and can close only the checkout; IP and network lists, rate limits, honeypots and the cart flood fix; a one-second challenge instead of a captcha; learning mode, dashboard, log, IP tester and Cloudflare export. No core changes, no OCMOD.
