On the desktop a saved file (a recovery phrase, recovery codes, an
archive with progress) is made the own user's alone (0600, chmod(2)
through the C library already in the process) on the emptied file before
anything is written, so no other user of the machine reads it; Windows'
files keep their folder's rights. On iOS, file_picker (darwin v2.1.2)
writes a copy into the app's temporary folder for the system's picker and
never removes it, saved or cancelled: it goes once the picker is done.
