NULVEX
NULVEX is described on its supplied site as AndroidIRCx, an IRC client for Android, rather than a notes vault.
What NULVEX is
NULVEX is described on its supplied site as AndroidIRCx, an IRC client for Android, rather than a notes vault. It supports simultaneous connections to multiple IRC networks and servers, channels, private messaging, and automatic server failover. Its IRCv3 support includes capability negotiation, and it also supports DCC file transfers and chat. The site lists end-to-end encryption for direct messages and channels with key verification, plus SSL/TLS for connections to IRC servers. SASL authentication is available for server login. For connections that use proxies, the app supports SOCKS5, HTTP CONNECT, and Tor. Other listed features include a JavaScript scripting engine with event hooks, custom commands, and timers; integrations with Bouncer/ZNC; and a services panel for NickServ, ChanServ, HostServ, and OperServ. Encrypted backup and restore covers settings, networks, keys, aliases, scripts, and lists. The project is open source under GPL-3.0. The download page offers Google Play and a direct APK, requires Android 7.0 or later, and recommends Android 11 or later. Google Play describes NULVEX differently, as an offline-first encrypted notes vault with optional zero-knowledge sync.

NULVEX’s supplied site presents a feature-rich Android IRC client with multiple network connections, encryption, and proxy options. Note the mismatch with the Google Play description before deciding whether this is the product you want.
