Whatever you collect, kept your way.
Sports cards, action figures, records, comics, Pokémon and Magic cards, books, video games, LEGO, stamps, sneakers, watches, or something nobody else collects. Start from a kind that comes with the right fields, then make it yours: your own fields, groups inside groups, tags, and checklists to complete.

🗂️ Your own fields
Each collection has the fields it needs: a card's player, set, number, and grade; a record's artist, pressing, and condition; anything you like. Text, numbers, money, dates, yes or no, choices, ratings, and private fields that are encrypted.
📁 Groups and tags
Groups inside groups (Baseball, then 1989 Upper Deck, then the rookies), tags across them, and filters on any choice or yes-or-no field: every rookie card, every sealed figure, every first pressing.
✅ Checklists
A set's numbers from 1 to 800, a figure line's wave, an artist's albums: fill each from what you have, see what's missing at a glance, and put it on your want list.
📈 Cost and worth
What you paid and from whom, each value over time, your gains on what you sell, and every collection's worth month by month.

🔐 Private, or shown off
Only you, and the people you share with, see your collections; photos, papers, private fields, and where things are kept are encrypted. Turn on a showcase to share a collection's pieces (never their prices) with a link.
Collector keeps your records. Values are your own estimates; it isn't an appraisal, or financial or tax advice.
