Ceklok

Ceklok is a mobile-based employee attendance application built to prevent proxy attendance and improve attendance accuracy using face detection and location validation.

Designed for daily operational use, Ceklok ensures that attendance is recorded only by legitimate users at approved locations.

Key Features

• Secure clock-in & clock-out with face detection and liveness check
• GPS-based location validation with configurable radius
• Device registration to prevent unauthorized access
• Attendance history with detailed records
• Leave request management
• Schedule change requests with approval workflow
• Web-based admin dashboard for monitoring and approvals

---

Approval & Validation Logic

Schedule change requests can be canceled before approval but are never deletable.
This preserves audit history and prevents manipulation after submission.

Each request follows a controlled status flow:
Pending → Approved / Rejected / Canceled

Invalid actions are blocked early with clear error feedback instead of silent failures.
