Frequently Asked Questions

What is a deadline board?
A deadline board lists your projects with their deadlines and visualizes how much of the available time has elapsed using progress bars, so you can see at a glance which deadlines are at risk.
Is this tool free?
Yes, it is completely free with no sign-up required.
Where is my data stored?
All projects are stored locally in your browser via localStorage. No data is sent to any server, so your information stays private.
Why don't I see the fullscreen button on my phone?
iOS Safari does not support the Fullscreen API, so the button is hidden there. All other features work normally on mobile.
How is the progress bar color decided?
Below 50% it is green, 50–75% yellow, 75–90% orange, and above 90% red. Overdue projects show a full red bar.
