Introducing ArkShelf

ArkShelf is secure private cloud storage for your files. Sign in on the web, use our mobile apps, and install desktop sync for macOS and Windows.

We focus on the workflows people use every day: uploading and downloading files, browsing folders, previewing common formats, switching between Spaces, and sharing files with secure links.

ArkShelf includes personal storage plus Family, Business, and Organization Spaces, secure file upload and download, in-browser previews for supported formats, and link-based sharing with optional protection.

Whether you are organizing personal archives or collaborating in a shared Space, ArkShelf is built to stay out of your way — private by design, available wherever you work.
