CAUTIONThe published web privacy policy says delivered messages are not retained and data is not sent to remote servers, but current clients use Nostr relays and Android 2.0.1 persists private conversation history locally. Bluetooth exposes proximity/relay patterns, Nostr relays can observe connection metadata, and a persistent device identifier is derived from the identity key.
