Messages is a simple SMS app for Android built with Kotlin and Jetpack Compose (Material 3). It is fully offline: the manifest declares no INTERNET permission, so your messages never leave your device except through your carrier.

Pin, archive, trash (+ undo) and delete conversations; swipe actions

No ads, no analytics, no trackers

Permissions

SMS and contacts permissions are used only to send/receive messages and show
contact names. The app requests no network access at all.
