Personal apps and tools built for speed and privacy first: a note app, a book reader, a video player, a CMS and an editor.
Kuro.Boo builds everyday tools around two rules: never make you wait, and never look inside your data. Opening instantly, and storing data in a form even we cannot read, are decided before any feature is added.
