Every screen in the app, in the order a store meets it.

1. 1

   Install from the Shopify App Store

   Shopify asks you to approve the permissions. Castor reads products, themes, and, if you allow it, orders. Nothing is written to your theme code.

2. 2

   Open Castor in Shopify Admin

   The app opens inside Admin under Apps. The left menu lists Overview, Popups, Widgets, Library, Studio, Products, Contacts, and Settings.

3. 3

   Finish setup

   Four steps: Products, Popups, Turn popups on, Add a widget. Each step opens the right Shopify screen and checks itself when you come back.

4. 4

   Turn one on, or place the block

   Popups and Widgets both open with a Ready to go set, already filled with your products and store name. A popup still needs the Castor App embed. A widget still needs the Castor Widgets block.

• Views, signups, and orders next to all store sales for the same period.
• Open carts, signups, and the popups and widgets that brought the most.
• A Setup button until every step is complete.
• Stat tiles link straight into Popups, Widgets, and Contacts.

Every number is a store total. Castor never shows a profile of one shopper, and the dashboard has no per-visitor view.

Creating one

Start from Ready to go, from a Library template, or from a blank design in Studio. The editor has two steps: Design, where you pick and adjust the creative, and Logic, where you say when it shows and to whom.

Logic

Coupons

A popup can show a fixed code you already have, or generate a one-use Shopify discount at the percent you choose when the shopper signs up. Generated codes are created in Shopify Discounts when you save the popup, so they work at checkout without any extra step.

Turning it on

Popups run through the Castor App theme embed. Turn it on once in the theme editor and every popup you switch on in Castor appears on the store. Switch a popup off in Castor and it stops showing on the store.

Placing a widget

Each widget has a Place button that opens the Shopify theme editor on the right template with the Castor Widgets block. Drag it where you want and Save. If you prefer, copy the shortcode and paste it into any Liquid section or page.

Widgets remember their height so the page does not jump while they load. They are shown only when the catalog has enough active products to fill them. If Theme Editor says Castor is loading your products, open Products, press Refresh from Shopify, and reload the editor.

Categories

Popups, Hero, Products, Bars, Toasts, Banner ads in the standard ad sizes, and Social. The Ready to go filter shows the designs that are complete with real copy and photos, so you can use them exactly as they are.

What each button does

Saved Templates holds the designs you saved from Studio. They stay in your account and are not on the store until you use them.

Elements

Every element has layout, color, size, and alignment controls. Product elements pick a product, a collection, or let the storefront fill them with the product on the page. Buttons and badges can open a link, apply a coupon, or add to cart.

Brand kit

Set your font, colors, and logo once. Library previews and new designs use them automatically.

AI

Describe a design in a sentence and Studio drafts it. Select a design and ask for a restyle. Image elements can have their background removed or replaced. Each action costs AI coins, which every plan includes.

Saving

Save puts the design in Saved Templates. Save and use does the same and then starts the popup or widget for you, so the next screen is the Logic step.

Pull, edit, Send

1. 1

   Pull products

   Copies your Shopify catalog into Castor. Castor also syncs on its own after install.

2. 2

   Edit

   Change title, description, price, compare-at, cost, status, tags, vendor, type, SEO title and description, and the main photo. Check several rows for a bulk status or tag change.

3. 3

   Send to store

   A dry run first lists what will change. Confirm and Castor writes it to Shopify. Nothing is written without that confirmation.

Export

Excel and Google Sheets CSV exports the whole catalog or the checked rows. Prices are in dollars. Columns: id, title, handle, status, product_type, vendor, price, compare_at, cost, sku, inventory, image, image_alt, description, meta_title, meta_description, tags, product_link, seo_score, units_sold, revenue, attributed_units, attributed_revenue. There is also a JSON export, a sales report, server backups, and Google, Meta, and Amazon feeds.

Import

1. 1

   Pick a file

   A CSV, a ZIP with a CSV and photos, or a folder. The export above imports back as is.

2. 2

   Map the columns

   Castor suggests a mapping from your headers and shows the first rows. Title is the only required column.

3. 3

   Review

   A dry run lists each row as create, update, or skip, and how many photos matched.

4. 4

   Confirm

   Updates keep the fields you did not include, including variants, galleries, and sales. New rows are created as active unless the file says otherwise.

• Unlimited contacts on every plan.
• Export the whole list to CSV at any time.
• Turn on Add to Shopify customers and each signup is created or updated in Shopify with marketing consent recorded.
• Shoppers who ask you to delete their data can be removed from the list, and Shopify redaction requests are handled automatically.

Instant Support

An assistant that knows your store's live setup: how many popups are on, whether the theme embed and the Widgets block are in place, how many products are pulled, and which page you are looking at. Ask a question in plain words and it answers with the step to take and a button that opens the right screen. It can also edit a product for you when you ask.

Custom Support

A ticket to the Castor team. Pick a topic, write what happened, and send. Your shop, the page you were on, and your browser details are attached so you do not have to describe them. Replies go to the email you give, within one business day — same day on Grow.

Contacts, views, visitors, every Library design, Design Studio, targeting, schedules, one-use codes, translations, and CSV export are included on every plan. A/B tests start on Startup. AI coins pay for AI drafts, restyles, SEO rewrites, and new product pictures.

• The storefront script sets no cookies. It uses the browser's own storage for that store only, to avoid showing a closed popup again and to count a view once.
• Merchants see counts. There is no per-shopper profile in the dashboard.
• Shopify's customer data request, customer redaction, and shop redaction webhooks are handled automatically.
• Orders are on the install list. We use units and revenue only, not a shopper profile.

The full privacy policy and terms of service spell out each item.

Export your contacts and catalog first if you want to keep them. Store data is deleted when Shopify sends the shop redaction request after uninstall.
