Why no phone number -
Murmur can’t read your messages.
They’re sealed on your device, and Murmur never holds the keys.
How encryption works -
No ads. No trackers.
We’ll never show you ads, sell your data or put trackers in the app.

Everything you’d expect.
It works like the chat apps you know, with privacy built in.

Questions, answered.
Is it free?
Yes. Messaging is free, and security, privacy and group size never cost extra. Optional extras are there for people who want more. No ads, ever.
Can I make calls?
No. Murmur is made for messages, whether text, voice messages, photos or files. There are no voice or video calls. To send a voice message, hold the microphone beside the message field. The recording is sealed end-to-end, like everything else.
How do my friends find me?
Share your link or QR code with them, or your username. Murmur adds two digits to the name you pick, like alibaba.46, and anyone who types the whole username can find you and send a request. You can turn that off in Settings › Privacy › Find Me by Username. You can also invite them from Contacts › Invite a Friend. The invitation goes from your own phone, and Murmur never sees their number. A stranger’s request waits in Message Requests, and they won’t know you’ve seen it until you accept.
Can people see when I’m online?
The people you chat with see “online” under your name, or when you were last seen. In Settings › Privacy › Last Seen & Online, you choose who sees it, whether that’s everyone you chat with, only your contacts, or nobody. With Nobody, your contacts see only “last seen recently” or “last seen a long time ago”. Strangers never see it, even after they send you a request, and Murmur’s servers don’t keep it.
What is Vault?
Your own chat, for the notes, photos and files you want to keep, and for copies of messages you save from other chats. Only you can read it, not even Murmur. It lives on your own devices, not in a cloud, and a copy you saved stays even if the sender deletes the original.
What if I lose my phone?
Save your Recovery Key from Settings › Security Center as soon as you can, and keep it somewhere safe. With your Recovery Key plus your password, you’re back in right away on a new phone. If you lose every device without your Recovery Key, your messages are gone, because Murmur never keeps a copy it could read.
What can Murmur see?
Not your messages, photos or files, and not who you talk to, because our servers don’t know who sent a message, or who is in a chat or a group. To deliver them, Murmur still sees a few things, like when a sealed message arrives. We publish the full list. Our Privacy Policy says what we keep, and why.
Is Murmur more private than Signal or Telegram?
Yes. Unlike Signal and Telegram, Murmur never asks for your phone number. Like Signal, it keeps its own servers from knowing who sent a message or who is in a group. Telegram’s regular chats and groups aren’t end-to-end encrypted.
Who checks Murmur’s security?
Independent security firms. They reviewed Murmur’s design, audited its code and tried to break in, and every report is published. The code that seals your messages is public too, so anyone can check it.
