Sync only the library and metadata without actual ebook files to Calibra Companion?

I would love to be able to access my Calibre library on my phone. I do not need access to the Calibre books itself, but I care about the book library management.

Is there a way to access the Calibre library on my Android phone?

I have custom columns (read status, finished reading date) and would like to access those as well - not sure if there is any chance to get access of all of that on Android.

Any options you are aware of I could try?
