About this Tool

Capture your thoughts and organize your day. Our To-Do List is a clean, simple, and persistent tool to help you keep track of your tasks. Add items, mark them as complete, and filter your view to stay focused. Your list is automatically saved in your browser, so it's always here when you need it.

The tool uses your browser's local storage (LocalStorage) to save your task list directly on your device. This means your data persists even if you close the tab or restart your browser, but it is never sent to any external server.

  1. Type a task in the input box and press Enter or click 'Add'.
  2. Click the checkbox to mark a task as complete.
  3. Use the filter buttons (All, Active, Completed) to change your view.
  4. Click the trash icon to delete a task.
  • Keeping a daily task list.
  • Tracking a shopping list.
  • Managing a mini-project's steps.
  • Persistent Storage: Tasks are saved automatically.
  • Filter Views: Easily see active or completed tasks.
  • Clean Design: No distractions, just your list.

LocalStorage is a web storage API that allows JavaScript sites and apps to store key/value pairs in a web browser with no expiration date.

Will I lose my tasks if I close the browser?

No, they are saved in LocalStorage and will be there when you come back.

Can I sync this with other devices?

No, the data is stored locally on this specific device and browser.

All calculations and data processing for this tool are performed locally in your browser. UtilToolkits does not send any of your data to an external server, ensuring your information remains private and secure.
