Bluetooth detection, no GPS

The people you actually cross paths with.

Someone caught your eye on the bus, in the coffee line, at last night's show? They're in your app. Not profiles from the other side of the city — people you genuinely crossed paths with.

Three steps

Go out. Cross paths. Discover.

On a bus at the end of the day, a woman and a man sitting across the aisle smile at each other, phones in hand. Bluetooth waves leave their devices and meet in the middle of the picture, between two illustrated profile cards.

You cross paths

Nothing to open, nothing to switch on. The app runs in the background and simply notes that two phones were in the same place.

What passes from one to the other isn't your profile: it's an anonymous token, renewed every fifteen minutes. The profiles only come together later, in the app.

In the evening, on his couch, a man smiles at his phone. ProxiBlu's encounters screen, shown in French, lists three people he crossed paths with, each with photos, age, and three buttons: a thumb, a heart and a trash can.

Later, you find them again

In the evening, the “Recent” tab shows the people you crossed paths with that day. A thumb to say you like them, a star to keep them as a favourite, a trash can to set them aside.

Without a mutual like, the encounter fades on its own — and they will never know you had liked them.

Each at home, a woman and a man smile at their phones. Both screens, shown in French, announce a match around their two photos, linked by a glowing heart.

If it's mutual, it's a match

The conversation opens, encrypted end to end. Your personal contact details, though, wait until you both agree to share them. Never before.

New · Social

The night is over. The gang doesn't have to be.

You had a great evening with people you didn't know, and everyone went home without swapping a single number? That is exactly what the Social tab is for.

On the left, a group of friends laughing in a country bar the night before. On the right, the next day, a man on his couch picks on his phone the people he crossed paths with between 8 and 11 p.m. to get the group back together.

Find the gang

Pick the day and the time range: the app shows you the people you crossed paths with during that time. Tick the ones from your evening, give the gang a name, and each of them gets an invitation.

Those who accept meet again in a members-only discussion. A decline is only told to the host and to the person who invited them.

Events

Drinks in the park, a karaoke night: invite your friends, your matches or people you crossed paths with. Everyone answers “I'm going”, “Maybe” or “No thanks”.

Groups

A lasting place for your crowd: a discussion, polls, events reserved for members. Private, by invitation — or public, for people nearby.

What's happening

Where should you go out to cross paths with people? The map shows the busy areas around you over the last 24 hours, as aggregated zones — never one person's spot.

The Social menu also offers “Create/Find a gang” (an open gang, to create or to ask to join), “Find one or more people” (if you crossed paths with someone but couldn't talk) and “Spontaneous activity search” (an activity within the next seven days, where others say they'll be there with one tap).

The difference

Chance already did the hard part. We just give it a second go.

Ordinary apps hand you strangers picked by an algorithm. ProxiBlu starts from the opposite end: the city already introduced you to hundreds of people today. We give you those people back.

You were already in the same place

Same neighbourhood, same hours, maybe the same café. You already share a life — that's a far better starting point than a profile found 40 km away.

No endless catalogue

You don't swipe through thousands of faces. You see the people from your day, and they disappear if nothing happens. Scarcity gives each profile its weight back.

Nobody learns anything about you

Your phone broadcasts nothing but an anonymous 16-byte token, renewed every fifteen minutes. No name, no photo, no location travels over Bluetooth.

Inside the app

What you'll find when you open ProxiBlu

Live

At the top of the Encounters tab, “Live” shows only the people around you right now, detected over Bluetooth, without your search filters. Useful in a bar or at a festival: you pick 10, 20 or 30 minutes or 1 hour, then the screen goes back to Recent on its own.

You can pick genders and an age range there, and how many people show at once: up to 50 with the free account, 100 with a paid plan.

Around my places

Work, the gym, a café: add by hand up to three places you frequent, each with a radius (two with the free account). Every day, the “My places” tab shows you people who frequent your areas: a thumb to like, a cross to pass. Two likes, and it's a match, no encounter needed.

For a festival, add your dynamic place: set where you are, with a 50 m radius, for 24 hours, it shows you the people who set theirs in the same spot.

No one sees your places or how far away they are. Each person only knows which of their own places matches. The server rounds the centre of your usual places: they never pinpoint an address.

The two-step match

A match opens the conversation and the description. Contact details — phone, Instagram, Facebook, Telegram — need a second agreement, from both sides. That step is never paid.

Encrypted messaging

Your messages are encrypted on your phone and decrypted on the other person's: even we cannot read them. A backup protected by a password only you know follows you from one phone to the next.

A typo? In the minutes after sending, you can edit a message or delete it for everyone.

Your friends too

Add your friends by phone number or email, or invite the ones who don't have the app through WhatsApp or another messaging app. Message each other, share your location for the length of an outing, and show them a match — if your match agrees.

You can also introduce them to someone you crossed paths with, if that person allows it, or to another of your friends: the person being introduced accepts or declines each friend.

Before a first date

From a match's profile, “Going to meet” keeps the place, date, time and a comment, for your safety. If you allow it, your phone sends your precise location at set times, before and during the meetup, and you can let friends on the app know. The person you're meeting knows nothing about it.

Share your live location with someone you trust, for 1 to 12 hours: the link switches itself off and never says who you are with.

Block and report

A block is immediate, silent and works both ways: the person stops existing for you, without being told. Every report is read by a member of the team.

Say hi if you cross paths again

After a match, ProxiBlu can discreetly let you know you are close by again. The alert only fires if you have both agreed to it, and without any GPS.

Privacy

Built to know as little about you as possible

A dating app built on proximity is one of the most sensitive things you can install on a phone. We built ours starting from that idea.

What we don't collect

Not your name, nor your date of birth, nor your address, nor your browsing history, nor your card number. We never read your phone's address book, and we create no biometric print of your face.

What Bluetooth carries

Sixteen unreadable bytes, valid for fifteen minutes, that only our server can resolve. A phone next to yours can deduce nothing from them: neither who you are, nor that it's the same person twice.

What the app never shows

Neither the place nor the time of an encounter: only the day. And it never tells anyone who liked them until it's mutual.

What you control

Geolocation is optional and revocable. You can download a copy of your data in one tap, and delete your account from the app or from the web — even if you have already uninstalled.
