While the na.pvrz.ml subdomain is hooked up to a freenom domain, the domain is connected to Cloudflare's nameservers, and the website itself is hosted through Cloudflare's Pages feature, which is also attached to this GitHub repository. The nvralone website does not contain any sort of trackers (however, this could be different on resource pages [Read their privacy policies!]), and does not contain advertisements.
If you find a vulnerability in the website and it's coding or hosting, please contact pvrz or email [email protected]
