Field notes
The homepage says the app’s collection and deck data stay on the phone, with no account required, and describes a single backup file for moving data to a new phone. Price information is attributed to Cardmarket’s public guide and YGOPRODeck; the page cautions that estimates may be as old as the last update. It also says screenshot corrections help improve later imports.
