I note you are using multiple tracking technologies, each of which have some Terms & Conditions you must conform to. Your embedded Google Analytics code carries the following condition, for example: "You must post a Privacy Policy and that Privacy Policy must provide notice of Your use of cookies that are used to collect data. You must disclose the use of Google Analytics, and how it collects and processes data."[0]
I see something called 'Hotjar' on the page too, and I imagine they have their own responsible disclosure and opt-out requirements, but one of my browser add-ons is blocking their site entirely and there is no way I'm disabling it to confirm my suspicions.[1]
Launching so soon after the GDPR came into effect, my only recommendation is 'begin to think about privacy' and consider adding a privacy policy page, so visitors know what is happening behind the scenes. Just be upfront about it, and consider removing any tracking that is not absolutely essential. Imagine a user uploads PDFs about a sensitive or personal topic, and visitors later discover you were silently tracking them without disclosing it. Are you OK with that?
