PlainApp: Phone Web Portal

**PlainApp** is a free, open-source Android app that turns your phone into a self-hosted management hub accessible from any web browser on the same network - no accounts, no cloud, no subscriptions.

**Why PlainApp?**

Most phone-management tools route your data through their own servers, lock features behind subscriptions, or show ads. PlainApp is different:

- **100% local** - your data never leaves your network
- **End-to-end encrypted** - every connection is secured with TLS + XChaCha20-Poly1305
- **Free and ad-free** - no purchases, no upsells, ever
- **Fully open-source** - audit the code, build your own binary, or contribute

**Features**

**Web-Based Phone Management**
Open a browser on any device connected to the same Wi-Fi network to manage your Android phone - no app installation required on the computer side.

- **Files** - Browse internal storage, SD card, and USB drives; upload, download, rename, delete
