The exact app to look for

Google Play name: Loci - Private, Offline AI
Developer: Cozu LLC (shown as Cozu on Google Play)
Android package: app.lociai.loci

AI that stays with you

Loci downloads a compatible model and runs it locally. After setup, everyday chat works without Wi-Fi or cellular service. No Loci account is required, and there are no ads or subscriptions.

Optional web search and model downloads use the internet. Anonymous crash and performance diagnostics are on by default, never include chats or personal content, and can be turned off anytime in Settings.
