Anonymous by default. Not as a setting.

An anonymous messaging app, by default

Most apps call themselves private but still know exactly who you are. Blockd is anonymous by default. No phone number, no email, no KYC. Your identity is a cryptographic key you control, not a profile tied to your real name.

Private is not the same as anonymous

Encryption hides what you say. Anonymity hides who is saying it. Most private messengers protect message content but still tie the account to your phone number, email, or a profile. Blockd removes the identity link itself.

No identity to hand over

No phone number, no email, no KYC. Nothing personal is required to sign up.

A key, not a profile

You are a cryptographic identifier you generate and control, not a row in a database tied to your name.

Nothing to correlate

With no phone number or email, there is no shared identifier linking your account across services or breaches.

How anonymity works in Blockd

Anonymity is the default state, not a mode you switch on. From signup to message delivery, Blockd is built to avoid collecting the identifiers that tie communication back to a person.

1

Anonymous signup

Create a cryptographic identity on your device. No phone number, no email, no KYC.

2

Blinded routing

Blinded routing tokens keep the network from mapping who talks to whom, when, and how often.

3

Optional Tor

Turn on Tor so your network location is decoupled from your account too.

No phone number needed

Anonymity starts at signup. Blockd needs no phone number and no email to create an account.

Messaging without a phone number

Hide your network location too

Route over Tor so your IP is decoupled from your account, on top of an already anonymous identity.

Anonymity is one layer. Blockd minimizes metadata across the whole stack, not just message content.

Coming from Signal?

Signal is respected software, but it ties your account to a phone number. See an honest comparison.

Frequently asked questions

What makes a messaging app anonymous?

An anonymous messaging app does not tie your account to real-world identifiers like a phone number, email, or government ID. Blockd identifies you by a cryptographic key you control, so there is no personal identity attached to the account.

Is Blockd really anonymous?

Blockd accounts are anonymous by default. There is no phone number, no email, and no KYC. Your identity is a cryptographic key, and blinded routing keeps the network from mapping who you talk to.

What is the difference between private and anonymous messaging?

Private messaging protects what you say, usually with encryption. Anonymous messaging also protects who is saying it, by removing the identity link. Blockd does both: post-quantum encryption plus anonymous, no-phone-number accounts.

Do I need a phone number or email to use Blockd?

No. Blockd requires neither. You create a cryptographic identity on your device, with no phone number, email, or KYC.

Can my messages be traced back to me?

Blockd is designed to minimize the identifiers that tie messages to a person. There is no phone number or email on the account, messages are post-quantum end-to-end encrypted, and blinded routing limits metadata. With Tor on, your IP is decoupled from your account too.

Is Blockd free?

Yes. The Blockd app is free to download, and Blockd Pro is free for everyone through December 31, 2026, with no code required.

Speak freely. Stay private. Be invisible.
