Cursus

Email that doesn't spy on you.

A fast, private desktop email client for Windows and Linux. Multi-account IMAP, SMTP & Resend sending, full-text search, keyboard-first.

No AI. No cloud. No tracking.

v0.1 in preparation — star the repo to follow.

Built for daily use

Multi-account IMAP

SSL or STARTTLS. Star, mark-read, archive and trash propagate to the server via UID STORE / UID MOVE.

SMTP or Resend

Two sending paths per account. Resend templates picker built in. Undo-send up to 30 seconds.

Full-text search

SQLite FTS5 with trigram tokenizer. Open with Ctrl+K, results in milliseconds.

Keyboard-first

Triage your inbox without the mouse. j/k navigate, e archive, r reply, c compose.

Portable

Drop the executable in any folder. Drafts, search index and sent log live in cursus-files/ right next to it. Zero registry pollution.

Secrets in OS keychain

Windows Credential Manager, libsecret on Linux. Passwords never live in plain text.
