LagrangeJust messaging.
Private, calm and safe — paid for by people, not ads. A messenger for your family and close friends in India.
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
What you get
Everything you need to keep in touch, and nothing that pulls at your attention.
Chats and groups
One-to-one and group chats with replies, read ticks you can turn off, and delete for everyone.
Photos, videos, files and voice
Share what matters, end-to-end encrypted like every message.
On your computer too
Link a browser by scanning a code with your phone. Your phone stays in charge and can unlink it any time.
Your number stays yours
People who don’t already have your number don’t see it.
Calm by design
No feeds to scroll and no counters to chase. Notifications are for messages from people.
Scam warnings Coming
Risky links and apps flagged before you tap, and Family Protection for elderly parents.
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.
Plans
Paid for by the people who use it, so it never needs your attention or your data. Free stays free; prices for Plus and Family will be announced before they start.
