3Fun presents a genuine puzzle. Its current privacy disclosure is the most restrained of any platform in this guide — it declares almost nothing tied to your identity. It also has, by some distance, the worst security history of any app we cover. Both of those are true at once, and no review that mentions only one of them is being straight with you.
How this review was done. A desk review of what the platform publishes about itself — its Australian App Store listing on 22 September 2026, including the App Privacy disclosure Apple requires every developer to complete, and its own website. Where we cite reporting by others, we say so and name them. We have not used the app under test conditions and will not pretend we have. We take no commissions and there are no affiliate links on this page.

What it is
The only app in this guide built specifically for three-person connections rather than adapted to them. Its own listing describes it as being for open-minded singles and couples, names gay, lesbian, bisexual, pansexual, polysexual, queer and transgender users explicitly, and offers verified photos so that, in its words, your dates look like their photos. Version 3.8.2 was updated in September 2026 and ships in seven languages.
If what you want is a third person rather than a couples-swap or a venue night, this is the platform designed around that. Feeld handles it too, with linked profiles, but as one configuration among many.
What it costs
| VIP, one month | $48.99 or $49.99 |
|---|---|
| VIP, three months | $59.99 |
| Priority Messages | $14.99 and $29.99 |
Two prices appear for the same one-month tier on the Australian store, which usually means a price change mid-flight or a grandfathered tier. The three-month rate is the obvious value if you are going to pay at all. Current at time of writing; check before subscribing.
What it collects today
This is the part that surprised us. Apple requires developers to declare what an app collects and whether it is tied to your identity, and 3Fun’s declaration is close to minimal:
- Linked to you: a user ID, for analytics, and your email address, for app functionality. That is the entire list.
- Not linked to you: message content, product interaction, crash data, and — importantly — precise location, declared for personalisation.
- Tracking across other companies’ apps: none declared.
Set against Feeld, which declares precise location, your contacts and sensitive information all linked to your identity plus cross-app tracking, or RedHotPie, which uses sensitive information for its own advertising, that is a materially more restrained posture. On the labels alone, 3Fun would come second only to SDC.
The 2019 breach, and why we lead with it
In August 2019, security researchers at Pen Test Partners disclosed that 3Fun was exposing the data of around 1.5 million users. The reporting was extensive and consistent — TechCrunch, The Register, Engadget and BleepingComputer all covered it.
What was exposed: precise real-time location, private photos, dates of birth, gender and sexual orientation. The app offered users a setting to restrict location sharing, but the filtering was applied only in the app and not on the server, so the underlying data remained retrievable regardless of what a user had chosen.
The detail that matters most is what that allowed. Researchers could supply any coordinates they liked and retrieve the details of users in that place — they demonstrated it against government buildings and military sites. Pen Test Partners’ Ken Munro described it as “probably the worst security for any dating app we’ve ever seen”. There were also reports at the time of users being blackmailed.
To be fair to 3Fun: they were notified on 1 July 2019 and had fixed it within weeks, and the company has since stated it rebuilt its security, encrypting sensitive fields including sexual orientation and serving photos through presigned URLs that expire.
How to weigh that in 2026
Seven years is a long time, the specific flaw was fixed, and a company that has been through a public failure of that kind often ends up more careful than one that has not. We are not telling you to avoid the app.
What we are telling you is that the privacy disclosure you read today describes intentions and current practice; it does not describe engineering quality. Those are different things, and 2019 is the clearest demonstration in this entire category of the gap between them. For an audience whose single largest concern is discretion, that is the most relevant fact available about this platform — which is precisely why you will not find it on the affiliate pages that dominate these search results.
The practical response is the same as for any app here, just applied with more conviction: a dedicated email address, approximate location rather than precise where the app allows it, and nothing in a photo you could not survive being linked to your name.
Who it suits
People specifically seeking a third rather than a couples exchange, and couples who want an app built around that rather than accommodating it. The free tier is unusually usable — unlimited messaging with matches is more than most platforms here give away.
Who should look elsewhere
Anyone for whom the 2019 history is disqualifying, which is a reasonable position to hold. Anyone wanting the Australian lifestyle scene rather than a global app — that is Adult Match Maker. Anyone whose priority is data minimisation with a clean record, where SDC declares no data linked to identity at all.
Questions people ask
Is 3Fun safe to use?
Its current App Store privacy declaration is among the most restrained of any app we cover. Its history is not: in 2019 researchers found it exposing precise location, photos, birth dates and sexual orientation for around 1.5 million users, with coordinates spoofable to query anyone anywhere. It was fixed within weeks and the company says it rebuilt its security. Both facts are relevant.
How much does 3Fun cost in Australia?
VIP is $48.99 to $49.99 for one month or $59.99 for three on the Australian App Store, with Priority Messages sold separately at $14.99 and $29.99. The listing states you can message matches for free without paying.
Does 3Fun track your location?
It collects precise location, but declares it as not linked to your identity and used for personalisation. That is a better position than several competitors, which link precise location directly to you. Given the nature of the 2019 flaw, use approximate location where the app allows it.
Is 3Fun just for threesomes?
It is built around three-person connections, which is what distinguishes it. Couples looking to swap with other couples, or wanting venue events, are better served elsewhere in this guide.
Prices and privacy disclosures come from 3Fun’s Australian App Store listing on 22 September 2026 and change without notice. The 2019 disclosure is attributed to Pen Test Partners and the outlets that reported it, and is included because it is material to readers of this site. Corrections to hello@swingershub.com.au.
