Leave or switch
If you have another workspace, switch to it from the workspace menu. Leaving a workspace detaches your membership; tables stay with the organization.
Delete account
Export first if you need a copy. Deleting the account removes you. Workspaces where you are the sole owner are deleted with the account. Workspaces that still have another owner remain.
Cancel a paid subscription separately in Billing if you no longer need the plan. See Exporting or deleting your data.
