If you want to permanently delete your Squarespace account, there are a few things you can do. First, you’ll need to login to your account and go to Settings. From here, you’ll find the Delete Account option. You can choose to delete your account completely, or you can choose to deactivate it.
deactivation will keep your account active but inactive, which means you won’t be able to access it or your files. If you’d like to permanently delete your account, deactivation is the best option.
