Cluster

Cluster is a private photo- and video-sharing service designed to help people stay connected without posting to public social media. Founded in 2012, the brand focuses on keeping personal memories safe and accessible for as long as users want to keep them. Members can create private groups, make albums, and invite only the people they choose. Within each group, they can share photos and videos, comment, chat, and receive notifications when new content is added. Members can also see which people have viewed and liked posts.

Cluster serves families, friends, clubs, school groups, teams, organizations, and other communities, with uses ranging from everyday updates to weddings, trips, and group events. The service is available through a web browser and mobile apps for iPhone, iPad, and Android, making it accessible across devices. In addition to digital sharing, Cluster offers photo books, allowing users to turn shared images into printed keepsakes. Its central purpose is to provide a simple, members-only space for sharing moments with selected groups, while keeping those memories away from public social feeds.
