What is the To-Do List Manager?

The To-Do List Manager is a private task management tool that lets you add, complete, filter, and delete tasks without any account or cloud synchronization. Standard task managers sync your to-do items to external servers, where they can be analyzed or stored permanently. This tool saves all task data exclusively in your browser's localStorage.

Tasks persist across page refreshes and browser restarts. Use the "Active," "Completed," and "All" filters to view your list by status. When you are done with completed items, "Clear Completed" removes them permanently.

How to Use the To-Do List Manager

Managing your tasks involves these steps:

  1. Type a task description in the input field at the top of the task panel (e.g., "Finish project report").
  2. Press Enter or click "Add" to add the task to your list instantly.
  3. Click the checkbox next to a task to mark it as complete. A strikethrough style confirms the status change.
  4. Use the filter buttons — "All", "Active", "Completed" — to narrow your view by task status.
  5. Click "Clear Completed" to permanently remove all completed tasks from the list.
  6. Click the × button next to any task to delete it individually.

Frequently Asked Questions

Are my tasks stored on your servers?
No. All task data is stored exclusively in your browser's localStorage. No tasks are transmitted to any server or cloud service.

Is there a limit to how many tasks I can add?
No hard limit is set. You can add hundreds of tasks. For practical productivity, we recommend focusing on your most important 3–5 items per day.

What happens if I clear my browser data?
Clearing site data for 99tool.in removes your localStorage, which will erase your task list. Copy or screenshot important tasks before a browser reset.

Can I set due dates or priorities?
The current version focuses on simplicity with a flat list and completion status. Priority tags and due date support are planned for a future update.

Privacy & Data Note
