Built to be private
Your chats are end-to-end encrypted, by default, with no setting to find. No ads, no data mining. Your conversations stay between you and the people you choose.
Chats are end-to-end encrypted
Every message, photo and voice note is locked on your device and unlocked only on the devices you sent it to. The keys never leave your phone, so the sealed copy we carry is one we cannot open.
Calls stay between phones
Voice and video flow directly device-to-device. The Nsibi backend relays the signaling that connects a call. It never sees, records or stores your audio or video.
You’re in control
You choose who can reach you, what you share, and how long it lasts. Block, mute and disappearing messages are built in, with no add-ons and no upsell.
Privacy you can actually feel
Small, practical controls that put you in charge of every conversation.
Disappearing messages
Set messages to vanish after they’re seen or after a timer, so a chat doesn’t stick around longer than it needs to.
Block & mute, instantly
One tap to block a contact or mute a noisy chat. You decide who’s part of your day and who isn’t.
Status only for your circle
Your status is visible only to people who share a channel with you, and every update disappears after 24 hours.
No ads, ever
You’ll never see an ad in Nsibi. We don’t read your messages to sell you things. Your inbox isn’t for sale.
Your data isn’t the product
We collect the minimum needed to deliver your messages and calls. Nothing to profile, score or resell you.
Quiet by default
Mute groups, leave conversations and clear your history whenever you want. Nsibi waits for you, not the other way round.
The least we can get away with
We only keep what’s needed to run Nsibi reliably, and we’re upfront about it.
To set up your account
A phone number and a display name, so people can find and recognise you. That’s the starting point, nothing more.
To deliver your messages
We hold the encrypted form of a message only long enough to reach your devices. We cannot read it, and disappearing messages are removed on schedule.
To keep calls connecting
We handle the signaling that sets up a call and mint short-lived relay credentials for tricky networks. The call itself runs between your devices.
What we never do
We don’t sell your data, we don’t build advertising profiles, and we don’t mine your conversations. There’s no third-party ad network inside Nsibi.
Privacy you don’t have to think about
Download Nsibi and start talking, privately and by default.
