End-to-end encrypted cloud storage and file-sync service built by a German company.

Filen is an end-to-end encrypted cloud storage and file-sync service operated by Filen Cloud Dienste UG (haftungsbeschränkt), registered in Recklinghausen, Germany.

All files are encrypted client-side before upload, so Filen’s own servers never hold the keys needed to read customer data. Desktop, mobile, and web apps support folder sync, share links, and file versioning similar to Dropbox or Google Drive.

The company positions itself as a privacy-first, GDPR-compliant alternative to US cloud storage providers, with plans for individuals, teams, and businesses.
