Rapid logging, monthly spreads, habit & mood tracking, fitness logging, and gendered wellbeing tools — all stored only in your browser. No accounts, no server, no tracking.

Most journaling apps lock your data behind a login and a subscription. bujo
keeps the calm, deliberate feel of a paper bullet journal — but adds the things
paper can't do: instant search, streaks, charts that overlay your mood against
your sleep, and one-click backups.
Most journaling apps make you pick one virtue. bujo refuses the tradeoff — it's paper-minimal in feel, quantified-self in power, and zero-knowledge in privacy, at the same time, for free.

Six things nobody else combines: local-first + free + no account · the real Ryder-Carroll method · a client-side correlation engine · gender-aware wellbeing · paper feel (book frame, dot-grid, handwriting, stickers) with digital power (search, streaks, charts) · honest data ownership (Markdown export → Obsidian).

npm run build # production build to dist/The app is a static SPA — deploy dist/ anywhere (Vercel, Netlify, GitHub
Pages). Your journal data never leaves the browser.
Everything is stored in your browser's localStorage under the key bujo:data.
There is no analytics, no network calls, no account. Because local storage can
be cleared by the browser, export a backup regularly (Settings → Export).
