ahrefs takes your personal data through their payment processor even before you have your own site login to ahrefs. Then, once the payment is processed, they make you go through hoops to verify ownership of a domain. When you skip these steps it sends you in circles, step 5 back to 1. You never reach the dashboard. I had to ask chat support for the link to the dashboard (!). In your profile you will find the data you provided to their payment processor (a separate entity) now within their own system. They claim to be GDPR compliant. I have my doubts. These people need to study basic UX to put the user in control, and get off their high horse!
