Cluster
Cluster provides private group sharing for friends and family outside social media. Members create groups for photos, videos, comments, and chat, with album access limited to invited users. Owners can share a private invitation link, and recipients can request to join. Notifications show when something new is added, while members can see who viewed or liked posts. Group photos can be turned into printed photo books. Cluster runs on Android, iOS, and the web, with no desktop app listed. Its free plan allows up to 10 groups, 1,000 photos per group, and 50 members per group; free video uploads are limited to one minute and SD quality. Cluster says photos are stored in redundant cloud locations and accessed over encrypted connections. Its policy describes SSL communications, does not guarantee complete security, and allows data downloads and deletion requests. Cluster is maintained by Fotoloce.
