The Task Deadline Reminder module is an Odoo app that sends automatic reminder emails to users responsible for tasks on their due date. It helps users stay organized and avoid missing critical deadlines by notifying them through scheduled reminders.

For a task to be considered for a reminder, the Reminder checkbox must be checked within the task's settings. Only tasks with this option checked will be included in the daily reminder checks.

Currently, the module sends a reminder to the primary responsible user of a task. If a task has multiple responsible users, you may need to modify the module to include all designated users in the reminder email.
