What does Anchor Partner mean?
An anchor partner is the primary, most central relationship in someone's non-monogamous network — the person or partnership that provides the stable foundation from which other connections are explored.

The term anchor partner describes the central relationship in a non-monogamous configuration. An anchor partner may or may not be someone you live with; a nesting partner is defined by living together. In the Lifestyle, this is often the couple — the two people who attend events together, share a joint profile, and whose partnership is the foundation of all other exploration.
The anchor partner concept is useful because it acknowledges relationship hierarchy without making it prescriptive. It says: this relationship has more weight, more history, more integration into my daily life — not because rules demand it, but because it genuinely does. That acknowledgment can prevent misunderstandings with play partners about what they can expect from the connection.
In polyamorous contexts, some practitioners resist the anchor partner concept because they prefer flat hierarchies. In the Lifestyle, the couple-as-anchor is simply the assumed default that the community is built around, and naming it clearly helps navigate interactions with singles and other couples.

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.
