The service provides an online cloud storage solution that lets users store, synchronize and share files. Files are kept on European servers and can be accessed through a web interface or native applications for iOS, Android, Windows and macOS. Features include two‑factor authentication, backups, and support for SFTP and WebDAV protocols, allowing secure file transfers and remote mounting.

It targets individuals or small teams who need a personal “hard drive” in the cloud, with options for multiple users and the ability to share photos, videos and other documents easily. The platform emphasizes privacy, stating that no data analysis is performed and that all infrastructure is hosted in the Netherlands by the provider’s own staff.

Distinctive aspects are the European‑based data centres, the inclusion of two‑factor authentication, and the availability of both web and desktop/mobile apps without reliance on large US providers. The service is offered in stable releases for macOS and other platforms.
