I think bandwidth and data caps are a hindrance to this. Looking on the bright side, at least something would have to be better in this dystopian future.

.bibisco2 are really just zip files which PhotoRec can find, if you want to use that. Good luck.

Bibisco2 is a JavaScript app, unlike version 1. It seems .bibisco2 files are only created when exported, otherwise it’s in a database somewhere. You can add custom formats in recovery tools like TestDisk and Photorec. I could look around and see if the database or the bibisco2 export files have a header, which I think is required to add a format.

Edit: Nevermind, there’s a paid version which creates bibisco2 files automatically.

For legal issues that are not EU-specific you may also want to take inspiration from this instance.
