What I'm adding

Added Privsen to two sections:

1. Cloud Storage - Zero-knowledge encrypted file sharing (up to 15GB)
2. Pastebin and Secret Sharing - Encrypted pastebin with self-destructing messages

Why it fits

• ✅ Zero-knowledge architecture (server never sees decryption keys)
• ✅ Client-side AES-256-GCM encryption
• ✅ No account/signup required
• ✅ Auto-expiring files
• ✅ Free to use
• ✅ Privacy-focused alternative to WeTransfer, Pastebin, etc.
