End-to-end encryption

AES-256-GCM — Zero knowledge

Notes are encrypted client-side before leaving your device. Keys are derived from an emoji-based passphrase — memorable, shareable, and never transmitted. The server never sees plaintext.

  • $ algorithm — AES-256-GCM with unique IV per operation
  • $ keys — emoji passphrase, stays in the URL fragment (never sent to server)
  • $ zero-knowledge — only key holders can decrypt
  • $ plan — Pro feature; free notes are unencrypted

Sharing & permissions

Shareable links

Every note gets a short URL. Share it anywhere — the recipient needs no account to view or edit.

Read-only mode

Share a view-only link for published content. Readers see the rendered output without edit access. Pro feature.
