ZAVOS Is Not a Sex Club. It Publishes a Constitution

ZAVOS publishes its full operating rules on its site in twenty-four languages. The eight articles of its charter and the thirteen house rules that go with them can be read by anyone without joining. What a site in this field usually publishes first is a price. São Paulo's best-known club raised its Saturday couples' entry from 215 to 285 reais in two years, the United Kingdom's largest swinger festival sold last year's tickets at £210 single and £250 per couple, and Germany's biggest platform listed more than 30,000 adult events and more than two million participant visits in a single year.

The name changes at every border. It is sex club in the United States, Swingerclub in Germany, club libertin in France, casa de swing in Brazil, ハプニングバー in Japan and 多人運動 in Taiwan, and whichever one you search, most of what comes back is a venue selling entry. The same is true of 갱뱅 in Korea. ZAVOS charges no entry. It posts a document instead. Everything below was taken from that published charter and those house rules.

The addendum

The charter's addendum is one sentence. A city may add rules of its own on top of the charter, but only in the direction of becoming stricter, and the power to relax anything is withheld explicitly. Neither the current organizers, nor the next generation of them, nor any city founded later is given authority to lower the eight articles. Constitutional lawyers call this a ratchet clause. It is the form international human rights treaties use when they declare certain protections non-derogable, and no emergency, government decision or majority vote suspends it. In adult gatherings the person opening the room normally sets the rules for that room; ZAVOS does not give cities that power.

Money

Article 6 provides that organizers serve unpaid. Costs incurred by a gathering are shared equally among the people who attend, and a host who says so in advance may set the split differently, but no money changes hands under any other heading. House rule 9 fixes how that is enforced. Money moves only between people and never through the platform — which is to say that no account exists for revenue to accumulate in. The São Paulo, British and German cases above are all real communities and also markets. Where takings are counted at the door, who gets let in is shaped by that count.

The nickname

Under house rule 3 ZAVOS collects nothing that identifies a member. It takes no legal name and no phone number, the only field it collects is an email address, and members know each other by nickname alone. The nickname carries one further condition. A nickname already in use on another online service may not be used here.

Most services online are built the other way round. Bringing an existing handle brings your reputation with it, so most of them encourage exactly that. A handle reused across several services is also the first thread anyone pulls when they want to connect a person's private life to a public account. ZAVOS cut that thread by rule rather than leaving it to each member's own caution.

The same principle runs through the rest. A photograph is seen once during entry screening, by the reviewing organizer alone, and is displayed nowhere. Recording at a gathering is prohibited except with an organizer's prior permission and on condition that faces do not appear, and a host may collect devices when the gathering begins. All real-time contact happens in text chat on the site, and members are told not to give out a phone number even to someone they have come to trust. The confidentiality Article 3 imposes covers the fact that a given person exists here at all, and it does not lapse when that person leaves.

No socializing outside gatherings

House rule 6 prohibits private socializing outside official gatherings. The rule states its reasons alongside it: identity protection collapses, factions and disputes form, and members who pair off stop taking part. Only people who knew each other before joining are exempt. Where an ordinary community spends its effort increasing the connections between members, ZAVOS placed a ceiling on connection itself.

What the door checks

The charter sets four conditions as common standards rather than leaving them to each host.

Age. No one under nineteen may become a member by any route. The line is written to admit no exception.

Consent. Every contact rests on active, explicit agreement. Consent may be withdrawn at any time without giving a reason, and contact stops immediately and unconditionally the moment it is. Silence or an ambiguous answer is not read as consent.

Health. Before a gathering that involves physical contact, a member must take the full standard STI panel used in the country they are in, and the result must be dated within one month. It is shown in person to the city's organizers, with the name and national identity number covered over first.

Limits. At gatherings organizers host officially, activity classed in the highest risk category is prohibited.

Article 8 provides that organizers are not exempt from the mutual rating system either. Their decisions must rest on that system and its procedure rather than on personal discretion. House rule 11 allows no conditions on leaving. Loading guilt onto someone who withdraws, or penalising them for it, is permanently forbidden and there is no retaliation.

How this differs from a swingers club

Swinger club, club libertin, parenclub and casa de swing are different names for the same underlying premise, which is that established couples exchange partners with other couples. ZAVOS members join as individuals, so no couple exists to be the unit of exchange. Group sex, threesomes, orgies and gangbangs are described in the glossary as arrangements each participant sets terms for separately. Membership applies across cities. A member who wants to attend a gathering elsewhere contacts that city's organizers through the site, because every city follows the same charter.

What people search, country by country

ZAVOS measured search volumes country by country in September 2026 and published what it found. The biggest term in every language measured turned out to be the one naming the act itself — orgy, gangbang, orgia, 群交, 갱뱅. Open the related searches, though, and orgy porn, gangbang porn, 群交 av and 갱뱅 야동 come attached to them. Those are searches for video.

Searches from people actually looking for somewhere to go name a place rather than an act. sex club, lifestyle club, Swingerclub, club libertin, casa de swing and ハプニングバー all carry "near me" and "what is a…" alongside them, and lifestyle club returned no video-related entry at all. Adding a word also collapses the volume. swingers measures 91 against a baseline of 100 while swingers club measures 8, and much of that 91 turned out to be swingers golf and swingers mini golf, the name of a British crazy-golf chain.

Cities

City communities run in Bangkok, Chiang Mai, Chicago, Dubai, Frankfurt, Las Vegas, London, Los Angeles, Mexico City, Mumbai, New York, Osaka, Paris, San Francisco, Seoul, Singapore, Taipei and Tokyo. One charter and twenty-four languages sit on top of them.

Frequently asked questions

What is ZAVOS? A city-based community for group meetups among independent adults. It is not a venue and not a party listing.

Is ZAVOS a swingers club? No. Swinging means established couples exchanging partners. ZAVOS members join as individuals.

Does ZAVOS cost money? There is no membership fee. Only the costs a gathering actually incurs are split equally among those who attend, and organizers and hosts take no financial benefit of any kind.

What information does ZAVOS collect? One email address. No legal name and no phone number. A nickname has to be newly created and cannot be one used on another service.

Can I attend in a different city? Yes. Every city follows the same charter, so one membership covers all of them.

What is the difference between a gangbang and an orgy? A gangbang centres on one person on terms that person sets in advance. An orgy is several people mixing, with no single centre. The rest of the terms are set out in the glossary.
