Keys stay on your phone

No copying private keys into random mobile apps. The signer keeps sensitive material isolated on your device.
  • Device-local vault
    Private keys are stored securely on the phone
  • Multi-identity support
    Multiple Nostr accounts managed cleanly
  • Focused signer
    A dedicated signer, not a bloated everything-app

Explicit approval flows

Every signing request is visible and deliberate. You see what's being asked before you approve or reject.
  • Clear request UI
    Signing requests presented with full context
  • Approve or reject
    Every request requires your explicit decision
  • Remembered permissions
    Remember approvals for trusted apps when appropriate

  • get_public_key
    Share your public key with requesting apps
  • sign_event
    Sign Nostr events without exposing the private key
  • NIP-04 & NIP-44
