Privacy by architecture, not by promise.
A truly private messaging app has to protect more than the words you type. Blockd protects your identity and your metadata too. No phone number, post-quantum encryption by default, and Tor routing so the network sees as little as possible.
Most apps equate private with encrypted. Encryption protects message content, but your identity and metadata leak around it: who you talk to, when, from what number, from what device. A private messaging app has to close those gaps too.
No phone number, no email, no KYC. You are a cryptographic key you control.
Blinded routing keeps the network from mapping your social graph: who, when, and how often.
Route over Tor so your IP stays separate from your account and messages.
Blockd applies privacy discipline at every layer, not just the message. Identity, encryption, and metadata each close a different gap.
A cryptographic key, with no phone number or email tying it to you.
Messages, voice, and video are end-to-end encrypted by default.
Blinded routing and optional Tor keep the network from profiling you.
Encryption is common. Identity and metadata protection are not. Here is the fuller picture.
| Feature | Blockd | Signal | Telegram | |
|---|---|---|---|---|
| End-to-end encrypted by default | Yes | Yes | Yes | Partial |
| Post-quantum encryption by default | Yes | Partial | No | No |
| Anonymous (no phone number) | Yes | No | No | No |
| Metadata minimization | Yes | Partial | No | No |
| Built-in Tor routing | Yes | No | No | No |
| User-controlled storage | Yes | Partial | No | No |

Privacy starts with identity. Blockd accounts are anonymous by default, with no name or number attached.
More on anonymous messagingNo phone number and no email to sign up. There is no SIM or carrier linking the account to you.
Messaging without a phone numberRoute over Tor so the network sees a Tor exit node, not your IP. Privacy at the transport layer too.

Compare Blockd and SignalA private messaging app protects more than message content. It also protects your identity and metadata: who you talk to, when, and from where. Blockd combines anonymous accounts, post-quantum encryption, and metadata minimization.
Yes. Blockd protects identity (no phone number or email), content (post-quantum end-to-end encryption by default), and metadata (blinded routing, with optional Tor routing).
No. Encryption protects what you say. Privacy also means protecting who you are and who you talk to. Many encrypted apps still tie your account to a phone number and leak metadata. Blockd closes those gaps.
No. Blockd requires neither. Your identity is a cryptographic key generated on your device, with no phone number, email, or KYC.
Metadata is the data about your messages: who you talk to, when, how often, and from what device or location. It can reveal your relationships and routines even when content is encrypted, which is why a private messenger has to minimize it.
Yes. The Blockd app is free to download, and Blockd Pro is free for everyone through December 31, 2026, with no code required.
