No calibre metadata in epub opf file when exporting
Hi everyone,
Is there a way to configure calibre to remove calibre metadata (and bookmark file) when exporting an epub? Or a plugin that would do the job? I don’t like my library data, like custom columns, leaking outside. Thanks. |

Turn off updating metadata in epub files if you dont want metadata written to them. Preferences->plugins->disable the epub metadata writer plugin. And turn off saving bookmarks inside epub file in the viewer preferences.

I think I did as you said but I’m still getting the data when writing to disk. What did I missed? |

The Modify Epub plugin can remove all non-dc (non-standard) metadata from the opf in an epub.

I've turned off the metadata updates in Calibre main and the editor. Also, I've turned bookmarks being saved in ePub from the viewer. When I save to disk, I have no problems. Nothing gets updated. You turn this off in Preferences > Saving books to disk. For the editor you do this in Edit > Preferences > Integr... with calibre. For the viewer you do this in Preferences > Miscellaneous. |

If you've disabled them there is no way they are being added. Start with a fresh epub and test.

Calibre keeps the metadata outside of the books. I nearly always edit the book epub to clean it. The editor was saving the calibre metadata into the epub. When viewing books, it was also adding the bookmark to the epub. These settings are now set as I wanted. I just have to clean my existing epub using the Modify Epub plugin. |

I'm curious about something. Why the paranoia about removing identifications / watermarks from books which have been licensed to you?
