Total Communication Privacy.
A private desktop messenger built for high-stakes privacy. No phone numbers, no tracking, just pure, quantum-ready security and total anonymity.
Privacy Shouldn't Require a Phone Number.
Most private messaging apps still link your identity to a phone number. Entropy breaks this link entirely. Your identity is a secure, random key generated right on your device.
Anonymity
No phone numbers. No emails. No metadata tracking. Entropy breaks the link between your digital identity and your physical self.
Post-Quantum Security
Built on the latest Signal standards, our encryption is Quantum-Ready, protecting your conversations against the threats of tomorrow.
Total Control
Your messages live on your device. Your keys are yours alone. No cloud, no central authority. If you're offline, our relay holds your encrypted messages for up to 7 days before they are permanently purged.
How to Use Entropy
Four steps to get started.
Generate Identity
When you first launch Entropy, it creates a secure local vault. This creates your private ID—a unique key that represents you without revealing a single piece of personal data.
Nicknames & UX
For a better experience, you can set a human-readable nickname. This maps to your Identity Hash, making it easier to share and recognize friends instantly.
Add & Chat
Share your nickname or ID to establish a direct, post-quantum encrypted session. All messages are padded into 1400-byte blocks to stay invisible.
Total Control
At any time, you can wipe your entire vault. Because we don't store your data on our servers, once you delete it locally, it is gone.
