土蔵 — the traditional Japanese storehouse with earthen walls three feet thick. Fireproof, built for centuries, trusted with what merchants valued most.
Dozō brings that same permanence to your personal collection. Books, vinyl, art, comics, film, whisky. Yours. Always.
Your library lives as a plain folder on your Mac. No servers, no subscriptions — just files you own outright, readable in any text editor.
Plain JSON, standard image formats. A 土蔵 was trusted with precious goods because nothing inside could be destroyed. Your data, same principle.
API lookups are suggestions until you confirm them. Nothing is committed without your hand on it. The merchant decided what was worth storing.
No bundled API quotas. Connect your own keys for lookup services — you own the relationship with every outside service.
Books behave differently from whisky. Plugin architecture means each domain gets the fields, logic, and views it deserves.
Built from the start for Japanese titles, scripts, and the kinds of objects — ukiyo-e, art books, doujinshi — that don't fit anywhere else.
Your entire collection is a folder. Move it, back it up, put it in iCloud. It works anywhere — because it's just files.
Each item gets a UUID folder with a plain JSON record, images, documents, and provenance. No database. No export step. No migration.
