Deleting a space removes it and everything in it — problems, contests, courses, members, submissions, scoreboards, content and results. The action cannot be undone. There is no archive, no recycle bin and no support request that brings the data back afterwards.
Before you start, be sure this is what you want rather than one of the alternatives below.
Export anything you might need later. Once the space is gone, so is every submission, scoreboard and member record in it.
Tell the people who use it. The public site stops working the moment the space is deleted, and its key becomes available for someone else to take.
Check whether you actually mean the subscription. Cancelling a plan stops the billing and leaves the space intact, inactive but recoverable — see Change your plan or seats. Deleting the space destroys the data.
You need permission to delete the space (Space → Delete). Without it the Space control card is not shown at all, so if you can't see it, ask whoever manages access — see Access management.
Open Settings → General.
Scroll to the Space control card.
Click Delete space.
Read the confirmation. It names the space you are about to delete — check that the name is the one you mean, particularly if you administer several.
Confirm.
The console returns to the space picker. The space is no longer listed, for you or for anyone else who had access to it.
Deleting is rarely the right move for a space you might want again. Two lighter options:
Make it private. Members must sign in, and nothing is visible to the public. The space keeps working for whoever you let in — see Public and private spaces.
Cancel the subscription. The space stays available until the end of the billing period and then goes inactive: the data is still there, and renewing restores access.
