We CAN'T See Your Data

This isn't a privacy promise. It's a technical impossibility.

Your messages are encrypted in your browser before they ever leave your device. We never see plaintext. We can't decrypt your data. We don't have the keys. Even if we wanted to spy on you—we physically cannot.

Traditional Services

  • Data stored on serversFiles sit on their infrastructure permanently
  • Provider has decryption keysThey can read everything you send
  • Vulnerable to breachesHackers get full access to plaintext data
  • Subject to subpoenasGovernment can force data handover
  • AI scans your contentAlgorithms read your private messages

HexBurn

  • Zero server storageData lives in URL fragments, never transmitted
  • You control the keysDerived from your password, never sent to us
  • Breach-proof by designNothing to steal—we don't have your data
  • Subpoena-resistantSelf-destruct means data is already gone
  • AI can't read encrypted dataWe see only indecipherable ciphertext

How It Actually Works

1. Client-Side Encryption

Your browser encrypts data using AES-256-GCM and Web Crypto API before transmission

2. URL Fragment Storage

Encrypted data is stored in the URL #fragment—which never reaches servers

3. Password Key Derivation

Keys are derived from your password using PBKDF2-SHA256—never sent to us

Zero Knowledge. Zero Data Collection. Zero Compromise.

Complete Feature Arsenal

Military-grade encryption meets cutting-edge privacy technology. Every feature designed for maximum security.

Military-Grade Encryption

AES-256-GCM encryption ensures your messages are protected with the same standards used by governments and military organizations worldwide.

Zero Server Storage

Your messages never touch our servers. Everything is encrypted and decoded directly in your browser using cutting-edge Web Crypto API.

Burn After Reading

Messages self-destruct immediately after being read. Once burned, they're gone forever with zero recovery options.

Zero Data Collection

No cookies, no tracking, no analytics, no user accounts. We literally cannot see your data even if we wanted to.

Time Capsule Messages

Schedule messages to unlock on a specific future date. Perfect for birthday surprises, time-delayed announcements, or future reminders.

Burn After Reading

Once opened, the message self-destructs immediately and can never be recovered. Complete privacy guaranteed.

Tools That Don't Exist Anywhere Else

HexBurn isn't just another privacy tool. We've built something genuinely unique: a complete ecosystem of zero-knowledge tools that combine features nobody else has put together before.

Time Capsule Encryption

Nobody else offers client-side encrypted time capsules. Set a future unlock date and the message is cryptographically locked until that moment arrives. Perfect for birthday surprises, scheduled announcements, or delayed secrets.

  • Browser-enforced time locks using Web Crypto API
  • No server-side date checking - pure client-side verification
  • Combines perfectly with burn-after-read functionality

Self-Destructing PDFs

Upload confidential PDF documents that are encrypted client-side and burn after a single view. No other platform offers true burn-after-read for PDF files with zero server storage.

  • PDFs never touch the server - encrypted in your browser
  • Renders directly from encrypted data using PDF.js
  • Perfect for NDAs, contracts, sensitive documents

P2P Encrypted Chat
