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
