Disclaimer:

This plugin performs license validation online via Google Sheets, which means your end users must have an active internet connection whenever a license check is performed. Please note that this system is designed as a lightweight and convenient solution for managing licenses, not as an enterprise-grade DRM. While it offers basic protection against unauthorized use, Ciji Games cannot be held responsible for hacks, bypasses, or data breaches.
