A standalone (not-cloud based) task management and timing app

Question

I'm wanting a task and time management app for use at work.

Ideally the app should not be cloud-based - as:

1. I don't need to be taking work home with me.

2. I don't want to have to worry about sensitive material being leaked through it.

The app should have the following features:

• Can create a task backlog.
• Tasks can be organised in to projects/labels.
• Supports Pomodoro or similar timing, with a clear label of what task I'm working on.
  • i.e. it would be nice nice if the app can show a breakdown of the day, with what tasks I've worked on, and how long it has taken.
• When a Pomodoro or break is finished - very prominant flashing screen.
• Doesn't talk to the internet / Doesn't need to talk to the internet.

Try my Portable Kanban. Disclosure: I'm developer of PK.

• it works offline
• it's free, can be used commercially.
• it works on Windows only.
• It has a Pomodoro timer that is configurable (work/short pause/long pause intervals, sound)
• It has a lot of options for configuring UI and board.
• May be used for teams too (requires Redis server).

Here's a screenshot of the task backlog:
