Filen: Zero-Knowledge Encrypted Cloud Storage with Linux and Android Support

Review in progress — Full personal review coming soon. Details below are confirmed facts about the service.

Overview

Filen is a zero-knowledge encrypted cloud storage and file sync service. Unlike many cloud providers, Filen encrypts your files client-side before they ever leave your device — meaning even Filen cannot read your data. The desktop sync client works reliably on Linux (Debian and Fedora tested) and the Android app provides solid mobile access.

Filen periodically offers lifetime storage plans — a one-time purchase for permanent storage without recurring fees.

Linux Support

Filen provides a native desktop sync client for Linux, available as an AppImage. It has been tested and works reliably on Debian and Fedora. The web interface provides full access to files without the desktop app.

Android Support

The Android app is functional and covers the essentials — browsing, uploading, downloading, and offline access. Camera upload is supported.
