Mobile apps support streaming, sharing, and device backup. Icedrive lists file versioning and zero-knowledge encryption. It says its client-side encryption protects file contents and names on the device using 256-bit keys. The plan comparison also lists encryption at rest and TLS 1.2/1.3 transfers. Paid plans include user-to-user sharing, with public links and controls such as expiry, download caps, preview-only mode, and passwords. WebDAV is disabled for new users and being phased out for existing users.
