A Contact Directory is a centralized list of names, phone numbers, email addresses, and roles for individuals within a group, such as a school, club, or workplace team. It enables quick communication and coordination without storing sensitive personal data beyond what is voluntarily shared. Entries are organized alphabetically or by department, and users can search or filter contacts easily. Privacy settings allow control over which details are visible to whom, ensuring respect for personal boundaries. Ideal for parent-teacher associations, volunteer groups, or small businesses, it replaces scattered paper lists with a secure, digital solution. No external sharing or data mining occurs, and all information is managed locally with user consent.
