MovieShelf is an independent software publisher whose source code and development activity are hosted on GitHub under the account lunasans, reflecting the open, community-oriented nature of its projects. The publisher's catalog consists of two desktop applications that address everyday personal organization and communication needs while emphasizing local data control and the use of open standards. The flagship product, MovieShelf, is a media management application designed for film enthusiasts who want to catalog and maintain their personal movie collections. It allows users to organize their films locally on their own machines rather than relying exclusively on cloud services, while also offering synchronization with the MovieShelf service so that collection data remains consistent and accessible across devices. Typical use cases include building a searchable library of owned or watched titles, tracking viewing progress, and keeping a curated archive of a home cinema collection. The publisher's second product, N-MailClient, is a desktop email client supporting the standard IMAP and SMTP protocols for sending and receiving messages. Beyond core mail functionality, it integrates calendar management through CalDAV and contact synchronization through CardDAV, making it suitable for users who want a unified personal information management tool that works with standards-compliant servers. Additional features include PGP support for encrypted communication and built-in translation capabilities, which serve privacy-conscious users and those who correspond across languages. Together, these two products illustrate a coherent publishing philosophy: practical, locally focused desktop software built on established protocols, giving users independence from proprietary ecosystems while covering collection management and secure, integrated communication.
