DragBin

DragBin is a cloud storage and sharing service built around client-side, zero-knowledge encryption. Files are encrypted on the device before upload, so the service says it cannot read the stored content. Its security architecture combines ML-KEM post-quantum key encapsulation with AES-256 encryption and Argon2 key derivation. The everyday workflow covers uploading, syncing, organizing, and sharing files across mobile, desktop, and web. DragBin supports unlimited file sizes on its listed plans and lets owners create password-protected or expiring links with view and download limits, geographic restrictions, watermarks, and engagement analytics. Recipients can access shared files without a DragBin account when the decryption key is provided. The platform can also bring Google Drive, Dropbox, OneDrive, and S3 storage into a central view. Professionals and teams can use version history, workspaces, role-based administration, single sign-on, and virtual data rooms for controlled collaboration. Creator-oriented plans add custom branding, domains, analytics, and encrypted e-signatures. A private AI assistant runs locally on the device for working with files. DragBin therefore fits privacy-conscious individuals, creators, legal teams, and organizations handling confidential material that need cloud access without giving the storage provider plaintext access.
