The CDT Portal app collects limited employee data such as name, email, mobile number, device ID, attendance timestamps, and location (only at punch-in/punch-out). It may access storage for work file uploads/downloads and use push notifications for important updates. Data is used strictly for attendance management, security, and communication. Information is never sold, only shared with employers or required services under confidentiality. Strong safeguards protect data, and employees can request access, correction, or deletion where applicable.
