Trust & safety
Four gates between a stranger and you
Most dating apps let anyone in and clean up later. Threesum works the other way around: nobody appears in browse until they have cleared every check. No catfish, no bots, no minors — by construction, not by moderation backlog.
A real document, not a checkbox
Before any profile can go live, every member submits a government-issued ID. No document, no profile — there is no way around this step, for anyone.
Your ID is checked, then immediately discarded. We never store it.Why Threesum
Built for the thing other apps tolerate
Mainstream apps treat couples as a loophole and non-monogamy as a filter setting. Threesum treats them as the whole product.
Verified-only, no exceptions
Every live profile has passed an ID check, an age check, and a face match. Not "verified badges for some" — verification is the price of entry for everyone.
Couples as equals, not add-ons
A duo profile represents both of you — shared photos, shared inbox, one honest presence. You were the reason this was built, not an afterthought setting.
Discreet by design
No social media linking, ever. No public browsing. Messages auto-delete after 30 days. Your life on Threesum is invisible to your life outside it.
A consent-first culture
Everyone here chose this space and said so with a government ID in hand. No explaining yourself, no converting the curious — just people who already want what you want.
Quality over quantity
A verification gate keeps the pool smaller — and that is the point. Fewer profiles, every one of them a real person who went through real checks to be here.
You hold the exit
Delete your account whenever you want and your profile goes with it. Between the 30-day message window and discarded IDs, there is very little left to delete.
How it works
Four steps, whoever you are
The journey is the same either way: show up honestly, prove you are real, and meet people who did the same.
Create your duo profile
One profile, both of you. Names, photos, and what you are hoping to find — written together, shown together.
Verify in minutes
Government ID, age check, face match. It takes a few minutes once, and it is why everyone you will meet is real.
Browse verified members
Singles and other couples, filtered your way. Everyone you see has cleared the same checks you did.
Match and talk it through
When the interest is mutual, a private conversation opens. Take your time — messages auto-delete after 30 days.
For the two of you
You are a team, and your profile should say so. A duo profile puts both of you in the picture — literally — so there are no surprises and no “oh, you didn’t mention a partner” moments.
- One shared profile that represents both partners
- Browse verified singles and other verified couples
- Filters that respect exactly what you are looking for
- A private space to explore together, at your pace
For the one of you
Being the third takes confidence — and deserves respect. On Threesum, solo members are not scenery for couples. You choose who sees interest from you, and every couple you meet is a real, verified pair.
- A solo profile that is fully yours
- Meet couples, other singles, or both — your call
- Every duo profile is two verified real people
- Match only when interest runs both ways
Discretion
Private is the default, not a setting
This part of your life is nobody else’s business. Threesum is built so that it stays that way — structurally, not as a promise buried in a policy.

Questions
Asked, answered
The things people want to know before putting an ID on the table.
Yes — structurally, not just by promise. There is no public browsing: only verified, logged-in members can see profiles. We never link to or import from your social media accounts, and messages auto-delete after 30 days. Nothing about your presence here is surfaced to the rest of your life.
Before any profile goes live, three checks happen: a government-issued ID is scanned and validated, your age is confirmed as 18+ from the date of birth on the document itself, and a live selfie is matched against the ID photo. Profile photos are then moderated before other members see them. Nobody skips the line — every profile you can see has passed all of it.
No. Your ID and verification selfie are checked and immediately discarded — we never store them. The only thing we keep is the result: that you are a verified, real adult. The full details are in our privacy policy.
You create one duo profile that represents both of you, with shared photos and one shared presence. You browse and match together, and anyone you talk to knew you were a couple from the first glance. No hidden partners, no surprises on either side.
Completely. Threesum is for couples looking for a third and for open-minded singles looking for couples — or for each other. Solo profiles are first-class: you say what you are open to, you match only on mutual interest, and every couple you meet is a verified, real pair.
Joining, verifying, browsing, matching, and messaging are all free. Optional paid upgrades are available inside the app for members who want more, and you can see exactly what they include after you join. Cancel anytime from your settings — no coins or pay-per-message tricks.
Yes. Age is not a checkbox here — it is read from the date of birth on a government ID during verification. If the document says under 18, the profile never exists.
Delete your account from your settings whenever you like, and your profile goes with it. Combined with auto-deleting messages and IDs we never stored in the first place, there is very little trace left to worry about.
The third you’re looking for is looking too.
Verification takes minutes. What it buys — a space where everyone is real, adult, and here on purpose — lasts as long as you stay.
