Cloud Storage Desktop Client for Secure File Sync
Sync local folders with your cloud, upload or download files in the background, and manage CryptFiles directly as a desktop client — without constant browser switching.
The CryptFiles Desktop Client brings secure cloud sync, uploads, downloads, live status and the full CryptFiles dashboard directly to your desktop.
With CryptFiles, you can sync directories, trigger sync actions directly, run uploads and downloads in the background, and monitor status inside the client.
The security principles stay aligned with the web platform: XChaCha20-Poly1305, encrypted fragments, chunk logic and a zero-knowledge-oriented model.
Why the CryptFiles Desktop Client?
XChaCha20 End-to-End Encryption
Every file is encrypted client-side with XChaCha20-Poly1305 before it ever reaches our servers. Only you hold the key.
Zero-Knowledge Architecture
We only store encrypted ciphertext. Your plaintext content is technically inaccessible to us – by design.
EU Servers – Stockholm, Sweden
All data stays in the European Union on servers in Stockholm. No critical data transfer to third countries, no US Cloud Act exposure.
Fully GDPR Compliant
Data Processing Agreement (DPA), GDPR-compliant privacy policy and transparent legal documentation – everything included.
