SDC review
SDC combines a dating directory for adults with groups, event listings and travel information. Its public pages show separate entry points for browsing events and opening a member account.
Trial access and a recurring plan
The registration terms distinguish trial access from paid plans. The paid plan determines which member resources are available. SDC says recurring billing is on by default. It directs members to Account Information to cancel before renewal. SwingLifestyle describes an Unlimited membership without recurring fees.

What a report can put under review
The signup terms say SDC can ask for proof of identity or a secondary check. The conduct rules tell members to report violations to management and say the service may review communications involving the parties. The privacy policy treats profile details and media shared through the service as personal data.
Anabel’s take
I’d browse the events for my area first. I’d take a plan only if it opened something I expected to use beyond that event list.
