Nostr Uno — your identities, your keys, your rules

Nostr Uno is a multi-identity Nostr key manager and NIP-46 remote signer for iOS, Android, and the web (PWA). Create multiple identities from a single seed phrase or import existing keys, then connect to Nostr apps via NIP-46 remote signing and switch between identities effortlessly.

Keys and seed phrases stay on your device: seed phrases are encrypted with AES-GCM in secure storage, private keys are derived in memory and never stored unencrypted, and identity profiles, connected-app records, and signing activity are kept in local device storage. There are no servers, no accounts, and no tracking of personal data.
