Cleeng or WooCommerce support

Hi, can you give me a slightly more detailed account of what you do with Cleeng? Also, we need to tackle WooCommerce. Given that it is a WordPress plugin, which means that you basically self-host, is there any data that goes through Woo? My thoughts, payments go through 3rd party payment providers, all of the other relevant data is done through WP backend? For sure this means that you should add at least the payment provider, then the "selling goods (...) online". Let's see how we get this done together, Simon
