What does Open Marriage mean?

Reviewed August 20, 2026

An open marriage is a marriage in which both partners explicitly agree that each may pursue sexual or romantic connections outside the relationship. It is defined by mutual consent and agreement, not by any fixed structure — the couple determines the rules.

An open marriage is distinguished from infidelity by explicit, ongoing agreement. The arrangement can include emotional or physical connections, equal or asymmetric permissions, and rules that change over time, but neither partner's consent can be assumed from the label.

The term is broader than swinging and less structurally specific than polyamory. What matters is the actual agreement, including safer-sex practices, disclosure, time, privacy, and the right to pause.

JoinTheSwing is designed for adults who have had those conversations. Identity review and privacy controls can support introductions; the platform cannot verify a couple's private agreement or guarantee discretion, compatibility, or conduct.

New member registration, when available, will be on the website and in the native apps; digital membership purchases take place in the native apps via StoreKit 2 and Google Play Billing. Existing members can continue using the website. At launch, member identity verification will run through an automated government ID, biometric face-match and liveness check by Veriff: from the current Veriff check JoinTheSwing never receives or stores the images — we retain the verification result, Veriff's session reference, a consent receipt and non-biometric review metadata. Members who verified through our earlier, retired in-house pass may still have ID, selfie or couple photos in our private verification-document storage, deleted when the account is deleted. The free launch list does not create an account, start a subscription or charge a card.
