Sindays describes itself as the largest community of swingers and libertines in Belgium, and its site works as a platform for meeting people and finding events rather than as a venue's own page. Its own framing is exclusive evenings suited to what it calls the trendy libertine lifestyle — for newcomers to the scene as much as for experienced libertines.

Its published event is White, an annual meet-and-greet dressed entirely in white, held at a location in East Flanders. Tickets are sold through its own ticket shop, and admission covers entry only — food and drinks are not included.
