Frequently asked questions

Ensō is a personal productivity suite: todo, agenda, calendar, reading list, projects, notes, email, and history in one tabbed app. It runs on the web, as a Windows/macOS desktop app, and on your phone — all backed by the same local database and sync engine.

Yes — on every platform, not just the desktop app. Each device keeps a real SQLite database (in the browser it's SQLite compiled to WebAssembly), so everything is readable and editable with no connection. Changes sync when you're back online.

A background loop reconciles your devices with the server every 15 seconds while you're online. Conflicts are resolved by one shared Rust merge engine that ships in every client, so two devices that made different edits offline always converge to the same result.

Everything travels over TLS. On top of that, Vaults let you lock specific lists, calendars, projects, or notes folders behind a password with end-to-end encryption (Argon2id key derivation, XChaCha20-Poly1305) — the server stores only ciphertext it cannot read.

The web app works in any modern browser and installs as a home-screen app on iPhone and Android. Native desktop apps are available for Windows and macOS (Apple Silicon and Intel). There's no Linux desktop build yet — Linux users can use the web app.

The installer isn't yet code-signed with a paid certificate, so SmartScreen shows a warning on first install. Click "More info" → "Run anyway". After installation the app updates itself with cryptographically signed updates.

The reading-list extension isn't on the Chrome Web Store yet — it's installed unpacked: download the zip from the download page, extract it, then load it via chrome://extensions → Developer mode → "Load unpacked". The getting-started guide walks through it.

Premium is $8/month or $80/year, and every account starts with a 14-day free trial (no card needed). After the trial your data stays on your devices; sync pauses until you subscribe. See pricing for details.
