How Bear CMS works?
As you already know, Bear CMS is a combination of client software (installed on your servers) and cloud services, that seamlessly integrate. A browser and internet connection is all you need to manage your Bear CMS website.
This is the place where your website is hosted. This is the place your domain is pointed. This is the place you can add custom code. This is NOT the place where you will find CMS code.
The Bear CMS cloud
Your website data is stored on your servers. When an administrator wants to modify it, and he needs the right tools, some of this data is sent to the Bear CMS cloud. It's never stored, and it is only used to return the needed tools (for example a form that enables editing a text block on the current page).
The Bear CMS team runs and supports the Bear CMS cloud (the CMS tools needed for your website). This enables regular features updates and bug fixed. In some cases (rarely) updates for the client software that runs your website will be available. That is why automatic updates are enabled by default.
