Export your collection
A CSV of everything you own, free. Pro adds a dated, sourced report as PDF.
Settings → Data → Export collection (CSV) writes every card you own, with its printing, quantity, condition, price paid and current value, to a file you can open in any spreadsheet. It is free and always will be: your cards, your data.
Zukan Pro adds the Collection report: a dated document listing every card, its condition, its value and where that value came from, as a PDF for insurance, an estate or a buyer. Every figure in it names its venue and its date.
