FAQ

Frequently Asked Questions

How does it work if it's just an HTML file?

Deadline Deck is a fully self-contained web application. All the code — HTML, CSS, and JavaScript — lives in a single file. Open it in any modern browser and it runs instantly. Your data is stored in your browser's localStorage, which persists between sessions without any server.

Is my data really private?

Yes. Your data never leaves your browser. There is no server, no database, no cloud storage, and no analytics. The file doesn't make network requests (except loading the Inter font on first use). If you need team sharing, the optional SharePoint integration keeps data within your firm's own infrastructure.

What happens if I clear my browser data?

Your deadlines are stored in localStorage, which can be cleared by browser cleanup. We recommend using the built-in weekly backup reminder (JSON export) and keeping regular backups. You can restore from a JSON backup at any time using the import feature.

Does it work on mobile?

Yes. Deadline Deck is fully responsive and works on phones and tablets. Open the HTML file from any file manager or save it as a bookmark for quick access.

Can my whole firm use it?

For team use, host the file on your firm's SharePoint site. It automatically detects SharePoint and creates a shared list for team sync. Everyone sees the same deadlines, updated every 30 seconds. The code is IT-department friendly and, if needed, can live on a shared drive or local server as well.

What browsers are supported?

Any modern browser — Chrome, Firefox, Safari, and Edge. Works on Windows, macOS, and Linux. No plugins or extensions required.

Is there a subscription?

No. Deadline Deck is a one-time purchase. You pay once and own it forever. All future updates are included at no additional cost.
