Import compatible files you are legally entitled to use. RetroSync ships with no games, artwork, catalogue, or download service.
Local first
Import and play on-device even when iCloud is unavailable. Automatic resume and named save states keep progress close at hand.
Private sync
Your library, saves, theme, and syncable per-game preferences use the private iCloud database of your signed-in Apple Account. Device-specific settings stay local, and the developer cannot read your private iCloud data.
