Multi-User Access lets multiple people securely use the same tool—such as a schedule, inventory list, or task board—with individual roles and permissions. Each user can enter, view, or edit data based on assigned rights, ensuring accountability and preventing conflicts. For example, a teacher may allow students to view a calendar but only staff to update it. All actions are logged locally, and no personal information is shared beyond what is necessary. Designed for classrooms, clubs, and small teams, it promotes collaboration while maintaining privacy and safety. No passwords are stored online, and access is controlled entirely by the user. The system is intuitive, requiring no technical expertise, making it suitable for users of all ages.
