The dedicated backup screen — pick the sections you want, pick how to bring them back.
Import / Export, open from Settings → Data
Open Settings and tap Import / Export under the Data section. The screen has an Export card at the top and an Import card below it.
Five sections are listed with check marks — tick any combination:
Tap Export and Song Hive builds a .songhive file containing only the ticked sections and hands it to iOS's share sheet.
Tap Pick file and choose a .songhive file from anywhere iOS's file picker can reach (Files, iCloud Drive, Dropbox, Google Drive, a share-sheet handoff). Song Hive inspects the file, shows you which sections it contains, and asks how to bring them in:
Songs in the file match against your library by id first, then by name + artist, so a cross-device import lines up with the same songs you already have.
If you're on the free plan and the projected library size after import would exceed the 15-song limit, Song Hive shows an upgrade prompt (or an "import the first 15" option) before touching your library.
Older exports from before the section picker existed are still accepted. Song Hive detects the legacy format automatically and pre-checks the songs, familiarity, and tags sections on the way in.
Import / Export is deliberate and file-based; iCloud sync is automatic and continuous. Use iCloud for day-to-day device-to-device; use Export for manual backups or selective transfers.
