Privacy-first, end-to-end encrypted Mail, Pages, Drive, and Calendar.

End-to-end encrypted notes, tasks, files, passwords, journal and bookmarks. Keyed by a 12-word BIP-39 phrase: no email, no password, no account to leak. The full client source for web, desktop and mobile is published, along with the encryption (XChaCha20-Poly1305, HKDF-SHA256, Ed25519) and the threat model, so the privacy claims are falsifiable.

Free, privacy-oriented, no bullshit. Just manage your stuff with ease.
