  As Rudy mentioned, I don't think the OP (Jesper) said that the
information/file(s) should be accessible by a file manager *on the
(Android) device*. That's your restriction, not his.

  Most, if not all, posters here have a computer. Jesper posted with
Mozilla Thunderbird, so he has a Windows or Linux (or mac?) computer
which he can use with a USB connection to his phone.

  As to "not all apps allow to backup their data.": With the USB
connection, one can backup all app-private folders and files, so one
*can* backup the data of all apps. Unless there's some other kind of
restriction you're not divulging.
