Voodoo Ecom Agency used to provide Shopify private app development when private apps were an option, but not that long ago, they were deprecated.
Unlike Shopify public apps that are available at the Shopify app store and can be used by any business, private apps are created for your store only and are supposed to work only with it. Still, it’s already not an option for today’s businesses as Shopify private apps were deprecated in January 2022. It’s not a big drama as you can opt for custom apps that are also designed exclusively for your store, but in contrast to Shopify private app developers, custom Shopify app developers don’t need to get access to your Shopify admin panel and API.
