GDPR sites that dont collect data

With all the GDPR information doing the rounds, i have been reading a lot in to it and have found nothing that deals in simple terminology for me.

I have 2 websites, 1 HTML, 1 word press. Neither of these websites gather or keep anyone's email address's or have a sign up for newsletter feature. Its has no T&C checkbox or anything that remotely gets kept by server or user.

Do i still need a disclaimer for any of this? Or, as my understanding, as long as the data isn't kept or used the sites are fine?

TIA
