Gander - Zero-permission offline Android file viewer

Show HN: Gander, an Android file viewer that asks for no permissions at all

Gander is a lightweight, open-source Android application designed to view virtually any file format without requesting a single permission. Unlike typical apps that rely on cloud services or extensive data access, Gander operates entirely offline, rendering PDFs, Office documents, media files, and code directly on the device. With a tiny 15 MB footprint and no internet permission, it ensures absolute privacy by preventing any data from leaving your phone. Users can browse folders via one-time system grants and enjoy features like pinch zoom, deep search, and Material 3 design, making it the ultimate secure tool for local file management.
