A lightweight, private, offline-first PDF & EPUB reader.

Desktop (Tauri v2 · React · TypeScript · Tailwind) and Android (Kotlin · Jetpack Compose) share one Rust core. Book files stay on disk; the app never uploads, indexes, or copies their contents.

Zero telemetry. No network permission. No account.

Features

Library — import PDFs and EPUBs; covers, titles, and authors from file metadata
Reading progress — resume where you left off (PDF page or EPUB CFI)
Desktop — sidebar layout, virtualized cover grid, keyboard shortcuts, drag-and-drop
Android — Storage Access Framework, Material 3, TalkBack-friendly
Privacy by design — SQLite holds only library fields; covers in OS cache; no INTERNET on Android

Stack: Rust (core), Tauri v2, React, TypeScript, Kotlin, Jetpack Compose, UniFFI.
