Find the last day to cancel every contract

Open or paste your contract list. CancelBy works out each notice deadline and gives you a calendar file of reminders. Your list never leaves this page.

How to check that your list stays on your computer
  • This page does not send your list anywhere. It keeps working with Wi-Fi turned off, so you can test that yourself.
  • The page's security policy blocks network requests. Anyone reviewing it can find connect-src 'none' near the top of the file.
  • Nothing is saved in your browser. When you close the page the list is gone, so download your results to keep them.

1. Add your contracts

In Excel, use Save As and pick CSV. The file opens on this page only.

You need at least three columns: a contract or vendor name, an end date or renewal date, and a notice period such as "60 days". You can copy cells straight from a spreadsheet.
