LagrangeQuiet nights
Messages still arrive at night; your phone just waits until morning to tell you. The few people you choose always get through, and anyone can mark something Urgent when it really can’t wait.
Just messaging.
A quiet place for you and the people you love. Paid for by people, not ads.
- CalmNothing pulls at your attention
- PrivateOnly your chat can read it
- SafeStrangers and scams stay outside
Why “Lagrange”?
In space, a Lagrange point is where the pull of two bodies balances out. Something placed there stays put: calm, steady, without fighting to hold its place.
That’s the place we want between you and your people. No feeds tugging at you, no ads, no strangers. Just the two of you, or the few of you, keeping in touch.
What you won’t find
Lagrange does one thing: messages between people. These stay out, for good.
- No statuses or stories
- No channels or feeds
- No ads, ever
- No messages from businesses you didn’t write to first
- No engagement tricks or streaks
- No selling your data
Made for real life
Three moments where Lagrange does the quiet, careful thing.
Scams get flagged
Fake KYC alerts, “digital arrest” calls, prize links: messages that look like known scams get a warning before you tap anything. It’s checked on your phone, so your messages stay private.
Strangers wait outside
Someone you don’t know lands in Requests with a short intro, never in your chats. Accept them, or restrict or block them without them being told.
What you get
Everything you need to keep in touch, and nothing that pulls at your attention.
Chats and groups
Replies, read ticks you can turn off, and delete for everyone. Nobody adds you to a group without your OK. Invite links and QR codes you can revoke.
Photos, files and voice
Share what matters, encrypted like every message. Send a file to someone who isn’t on Lagrange with a private link that expires.
Voice and video calls
One-to-one calls, encrypted end to end, made to hold up on a weak 4G signal.
On your computer too
Link a browser by scanning a code with your phone, and your recent chats come along. Your phone stays in charge.
Your number stays yours
People who don’t already have your number don’t see it; share a contact link instead. A PIN stops anyone taking over your number.
Backups only you can open
Your chats are backed up encrypted, with a recovery key that only you hold, so a new phone can bring them back.
How privacy works
Not a promise in a policy: it’s how the app is built.
Encrypted on your phone
Every chat, including one-to-one, uses MLS, the open IETF standard for end-to-end encryption. Only the people in the chat can read it.
Our servers can’t read messages
They pass along scrambled data and delete it once it’s delivered (or after 30 days). Photos and files are encrypted before they leave your phone.
Little to know about you
We keep your number encrypted, your chosen name and your devices. Finding friends checks numbers and stores none of them.

Questions
Short answers to what people ask first.
Is Lagrange free?
The beta is free. After that, Lagrange is paid for by its members instead of ads. The people a member brings into their groups join as guests, free, so a family needs only one membership.
Can Lagrange read my messages?
No. Messages, photos and files are encrypted on your phone with MLS, the open standard for end-to-end encryption, and only the people in the chat have the keys. Our servers pass along scrambled data and delete it once it’s delivered.
What if my family isn’t on Lagrange yet?
Bring them in: as guests they join free to talk with you. Until then, you can still send them a file or ask them for one with a private link that expires.
Why another messenger?
Because messaging got crowded with statuses, channels, ads and business messages. Lagrange keeps only the part that matters: talking with your people, privately and without distraction.
How do I join?
Install the app (see below) and sign in with your mobile number. During the beta, new accounts get member features free while beta places last; after that, you can still join groups a member adds you to.
