Why is Cluster charging a subscription?

Our mission is to create a private place for families and friends to share their most precious memories. Part of respecting that privacy means we will never sell ads or sell your data. Instead, we are supporting the service and our communities by selling merchandise, like photo books, and now opening up our service to subscriptions with enhanced features. We still maintain a free tier of service. We hope you continue to love the service and we are dedicated to adding enough value into our subscriptions to make being a member a no-brainer.
