Apologies for the silly question. I have a few ebook files that I opened with calibre and it worked just fine until a few days ago I came across something in a site that said that calibre may be automatically uploading books to a cloud space where just anyone can access it.

Is there such a feature that uploads files without the user knowing? If so, how can I make sure that it does not ever happen?

Thank you in advance.

Very sorry again if the question is silly
