From d10d1dd52a4769541aaf19b84076df0003b7b446 Mon Sep 17 00:00:00 2001 From: Anthony Ettinger Date: Wed, 1 Jul 2026 09:10:41 +0000 Subject: [PATCH 1/4] Add site-wide JSON-LD + OpenGraph/Twitter/canonical metadata Add Organization + WebSite JSON-LD to the root layout and SoftwareApplication JSON-LD to the homepage. Add metadataBase, OpenGraph, Twitter Card, keywords and title template. Split the homepage into a server wrapper (page.jsx, exports metadata) and a client component (home-content.jsx) so it can carry a canonical URL, and add a "How it works" list + audience statement.

How QryptChat Works

+

Private by design — no email, no passwords, no message access.

+
+
    +
  1. Register with a phone number. A one-time SMS code verifies you — no email address and no password to leak.
    2. +
  2. Keys are generated on your device. Your ML-KEM-1024 key pair never leaves your device, so QryptChat cannot read your messages.
    3. +
  3. Every message is encrypted end-to-end. Text, files, and voice & video calls are protected with NIST-approved post-quantum algorithms.
    4. +
  4. Stay private, everywhere. Use QryptChat on the web or over Tor, and self-host it from the open-source (MIT) repository.
    5. +
+

+ Built for privacy-conscious individuals, journalists, activists, and security-minded teams who need + communication that stays private even against future quantum computers. +
