About

PlainApp is an open-source Android application that turns your phone into a self-hosted management hub accessible from any web browser on the same network. It operates 100% locally with no cloud dependencies or accounts, ensuring data sovereignty. Features include file management, SMS/call handling, screen mirroring, and built-in tools like Markdown notes and RSS readers. All connections are secured with TLS and XChaCha20-Poly1305 encryption, providing a privacy-first alternative to proprietary tools.
