Links being indexed by Google

Just wondering if there’s a ‘noindex’ setting I have missed somewhere? I use the plugin on my site at https://www.nodepositmobile.co.uk and it’s brilliaaint but I just noticed that the links are being indexed by google.

Should I just add something to my robots file or is there a built in setting?

Thanks ??
