+## 🔐 Security Notice
+
+lazyssh does not introduce any new security risks.
+It is simply a UI/TUI wrapper around your existing `~/.ssh/config` file.
+
+- All SSH connections are executed through your system’s native ssh binary (OpenSSH).
+
+- Private keys, passwords, and credentials are never stored, transmitted, or modified by lazyssh.
+
+- Your existing IdentityFile paths and ssh-agent integrations work exactly as before.
+
+- lazyssh only reads and updates your `~/.ssh/config`. A backup of the file is created automatically before any changes.
+
+- File permissions on your SSH config are preserved to ensure security.
