Privacy statement

No server-side storage at DNS Radar.

Recent domains stay local in your browser. DNS queries go straight from your browser to public resolvers (Cloudflare, Google), and registration lookups to the public RDAP registries. If your browser can't reach those directly, for example because of a firewall or ad-blocker, the lookup runs through DNS Radar's own Cloudflare Worker. That only forwards the domain and stores nothing. To keep that route from being abused, Cloudflare Turnstile checks in the background whether you are a real visitor. It does so invisibly, without cookies and without anything to click; Turnstile looks at properties of your browser, not at who you are or what you look up. Visitor numbers come from Cloudflare Web Analytics: cookieless and aggregated, so no personal profiles.

The Mailheaders tool parses pasted headers entirely in your browser. They are never sent anywhere. Only the explicit, opt-in blacklist check sends the sending IP addresses (not the headers) to the public DNSBL resolvers.
