Unlike other online signature services, **Smart CSC PDF E-Signer** processes everything directly in your browser. Your uploaded PDF, drawn signature, or files are **NEVER** sent to any external server.
Our rendering engine uses native HTML5 canvas and client-side binary compilation (`pdf-lib`), meaning the signing process remains 100% private, safe, and works entirely offline.
