how it works waitlist

How it works.

What whispr protects, from whom, and what it can see.

Your messages

Only the people in the conversation can read them.

DMs, group chats, and private servers are end-to-end encrypted: locked on your device, unlocked only on theirs. We can't read them, and neither can the servers in between.

What a relay sees

Enough to deliver a message, never what it says.

Relays are the servers that pass messages along. A private message reaches them without the sender's name, the conversation's name, or its exact length.

They can tell which messages belong together, and the relay hosting a server knows who is in it.

They also see your internet address, and when you connect.

Two kinds of server

Private for your people, community for a crowd.

The creator picks. Private servers are end-to-end encrypted. Community servers trade that for size.

private For the people you trust.
  • Friends, family, or a team, up to 1,000 people.
  • Only members can read it. Not us, not whoever hosts it.
  • Remove someone and they can't read future messages.
  • A stolen key can't open previous conversations.
community For a crowd.
  • Scales to over a million people.
  • Share one link and anyone can join and read along.
  • Newcomers can scroll back through previous history.

Quantum computers

Locked twice.

Someone could record messages today and wait for a quantum computer to open them. DMs, group chats, and private servers use today's standard encryption plus newer encryption built to resist quantum computers, so they stay locked.

Your account

Your account is a key, not a server.

On Mastodon or Matrix, a server makes your account and puts its name in your address. In whispr, your account comes from a key your device makes. No phone number, no email, and no server's name.

@you

your account

your devices

  • your key
  • your messages, readable

The key is made here and never leaves unencrypted. Lose a device and you can cut it off.

outside it

a relay

  • your messages, locked

Keeps them while you're away. Anyone can run one.

the directory

  • @you
  • your public key
  • your avatar

Lets friends find you. It never handles your messages.

Nobody's network

No company in the middle.

Anyone can run relays, and they pass messages between each other. Break into someone's relays and you reach their users, not everyone. Run your own and a breach reaches only you.

Higher stakes

Built for people a government might be watching.

Designed with journalists and activists in mind. Nothing hides you from someone watching the whole internet at once, but these help. Off by default:

Tor Hides your internet address from relays.
Traffic shaping Blurs the rhythm of your traffic.
Decoy lookups Hides which usernames you look up.
