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.
