Koofr

Koofr is a privacy-oriented European cloud storage service that centralises files across devices and connected third-party clouds — with client-side encrypted Koofr Vault and unified search across all linked accounts. Users get a single namespace spanning Dropbox, Google Drive, OneDrive, and Koofr itself, with no activity tracking or content scanning on the company's servers.

The platform runs across web, desktop apps for Windows, macOS, and Linux, and native mobile clients for iOS, Android, and Huawei. Online document editing is available through Office for the web integration, and secure sharing uses expiring links with granular permission controls.

Key benefits:

• Koofr Vault provides zero-knowledge client-side encryption for sensitive files
• Unified search finds files across Dropbox, Google Drive, OneDrive, and Koofr
• Office for the web enables in-browser editing of documents and spreadsheets
• Expiring share links with password and permission controls
• No tracking or scanning of user content or activity
• 10 GB free tier available permanently without a credit card
