Is there a way to change the privacy policy checkbox message?

Could someone please tell me if there is a way to change the message in the privacy policy checkbox in this plugin? I want to change the message to “By using this form you agree with the storage and handling of your data by this website in accordance with our Privacy Policy”. It is do with the GDPR.

I don’t really know how to change or add code to a plugin though. Unless someone can guide me through it.
