Is 3Fun Safe? 2026 Safety Report

3Fun Safety Analysis

3Fun scores 6/10 on our safety review as of March 2026. It's a threesome and couple-seeking app with a real user base, but its 2019 security incident - where researchers at Pen Test Partners found the app exposed full user location data, including profiles of users marked as 'hidden', without authentication - is relevant history. The company patched it, but that type of API-level exposure reveals an infrastructure mindset that's worth knowing about.

We checked the technical security: HTTPS is active, the app is available on iOS and Android with standard store distribution. Age verification is self-declaration at signup only - no document check. The privacy policy covers data collection (location, device identifiers, profile content) and notes data sharing with 'service providers' in general terms without naming specific third parties, which is less transparent than what GDPR-compliant apps like Feeld provide. Ad behavior on the free tier includes promotional notifications and profile boosts, but no malware-risk redirects. 3Fun reported over 1.5 million downloads as of 2023, primarily in the US, UK, and Australia.

Billing on 3Fun uses in-app credits for the 'VIP' Premium tier, which runs $19.99/month as of March 2026. App Store and Google Play handle the billing, which means statement descriptors are Apple or Google branded rather than 3Fun-specific - good for discretion. Free tier requires email only. Cancellation runs through your app store subscription panel. Refunds follow platform policies. We couldn't verify whether web purchases use a different descriptor - this varies by payment method.

Bottom line? 3Fun works for couples and singles exploring threesome arrangements, and millions do use it without incident. That said, share the minimum profile info necessary, turn off precise location when not actively using the app, and check your App Store billing after signup. The 2019 incident was patched, but our hot take is that niche hookup apps in general have weaker security teams relative to their user base size than mainstream apps like Tinder or Grindr.
