Nerddi App is a command surface for the Nerddi Network. CentroShield remains the identity authority; QRSocial owns social relationships and Messenger; Nerddi OS owns gaming state; CentroDrop owns assets; ExoEthos owns mail; QRBull owns QR Notes.
The Nerddi App database stores only app-specific preferences, pins, recents and local activity. OAuth access tokens and CentroSky credentials are kept server-side and are not intentionally exposed to browser JavaScript.
