Pomodoro Timer Chrome extension

This Pomodoro Timer runs entirely in your browser, tracking focus sessions and to-do lists without an account or internet connection. It's best for anyone who wants a simple, private timer that keeps working when the popup is closed. The catch: it's storage-limited to the browser, so there's no cloud sync if you switch computers.

What this Pomodoro Timer does

It's a local-first Pomodoro timer with a built-in to-do list that runs entirely offline. The timer engine schedules countdowns from absolute timestamps, so a session keeps running even after you close the popup or the browser suspends the extension, and it surfaces a desktop notification and alarm when the session ends.

Free vs paid

The extension is free with no paid tier, account, or subscription. All features, including the timer, to-do lists, and daily history, are available without payment, and all data stays in the browser's local storage rather than a paid cloud service.

Is this Pomodoro Timer safe?

It's built to be local-first: it doesn't send your tasks or timer data anywhere. Since it doesn't sync to a server, there's no cross-device backup, so clearing browser data or switching machines means losing your task history unless you export it first.

Pomodoro Timer: FAQs

Is the Pomodoro Timer extension free?

Yes, it's completely free with no paid tier, account, or subscription required.

Is the Pomodoro Timer extension safe to use?

Yes, it's local-first and works offline, meaning it doesn't send your tasks or timer data to any server.

How do I use the Pomodoro Timer extension?

Install it, add tasks to the built-in list, then start a focus session. The timer keeps running in the background even if you close the popup.

Does the timer keep running if I close the popup?

Yes, the countdown is scheduled from absolute timestamps and continues in the background, even if the browser suspends the extension.

What are Pomodoro Timer alternatives?

Forest, Marinara, and Focus To-Do are other Pomodoro-style extensions with different feature sets and account requirements.

Does this extension sync across devices?

No, all data is stored locally in the browser, so it doesn't sync between different computers or browser profiles.

What are the default timer lengths?

The current version uses the standard 25-minute focus session, 5-minute short break, and 15-minute long break as defaults.

Can I edit or delete tasks after completing them?

Yes, completed tasks can be edited or deleted, and destructive actions like deleting a task now ask for confirmation with an undo option.

What happens if I fill up the storage quota?

The extension guards every storage write and surfaces an error instead of silently losing data, and Settings shows a live storage meter.

Does the extension track daily history?

Yes, it records completed sessions by day, keyed to each list's identity so lists with the same name don't merge into one another.
