Turn sections on or off, and use the arrows to reorder them on the main screen.
Import Data
Choose a Recallorie export file (a full backup, or an older Export Foods / Export History file), then pick how to bring it in.
Merge adds the imported data alongside what's already here (matching foods/notes are updated, everything else is added as new). Replace erases everything currently stored first - use this only if you're intentionally restoring from a backup and want to discard what's currently here.
