how can i leave jira sites?

I started using jira as a student and now I have several abandoned project sites, is there any way I can get out of those sites?

Hello @mon.andres02 

Welcome to the Atlassian community.

Are those sites that you created, or were they created by somebody else and you were invited to join them?

If you created the sites then @Vikrant Yadav 's answer applies. You can cancel the subscriptions to the products on the sites and delete the sites if you are the person who set them up.

If these are sites you were invited to join, you cannot remove yourself from them. You would need to contact the owners/administrators of the sites and ask them to remove your access.
