This is the way it used to be and how we handle it here: private words between two people, remembered by hearts, not servers.
What Is CryptoNotes™?
CryptoNotes™ is our trademarked, end-to-end encrypted messaging system built exclusively for Love Yellow Pages members. It's not just another chat app — it's a fundamentally different approach to digital communication:
- Zero message storage: No databases, no data centers, no cloud backups of your conversations.
- 24-hour auto-deletion: Messages cryptographically shred themselves after 24 hours.
- Instant manual deletion: One tap — "Shred" button — and the message is gone forever.
- Friend-gated: You only receive messages from people you've accepted as friends.
- Your keys, your device: Private keys never leave your phone (iOS Keychain / Android Keystore).
How It Works
🔐
E2E Encryption
X25519 + ChaCha20-Poly1305 via libsodium. Only you and your friend can read.
⏱️
24-Hour Lifecycle
Auto-shred timer starts on delivery. Manual shred anytime.
🤝
Friend Requests
Mutual acceptance required. Un-friend anytime = instant block.
📱
Phone ID
Your phone number = your CryptoNotes™ ID. Linked to your LYP account.
Technical Architecture
Zero-Knowledge Architecture:
• Client generates Ed25519 key pair on first launch
• Private key stored in Secure Enclave (iOS) / StrongBox (Android)
• Public key uploaded to directory server
• Web platform NEVER has access to either key
Friend-Filter Gateway:
• Server checks Friendships table (mutual ACCEPTED status)
• No friendship = message dropped at gateway
• Un-friend = immediate routing revocation
Offline Queue (24-hr TTL):
• Encrypted payload queued if recipient offline
• SQL Agent job purges every 15 minutes
• On recipient login: download + immediate server DELETE
Local Secure Shredding:
• SQLCipher local database on device
• Manual/Auto delete → secure overwrite (random bytes)
• Forensic recovery impossible
Seamless Integration with Love Yellow Pages
CryptoNotes™ shares your Love Yellow Pages identity:
- Same username and password (single sign-on)
