Privacy Policy
Last updated: 28 September 2026
Domain Scanner shows public registration, DNS, hosting, SSL certificate and redirect information for a website, together with the abuse contacts of its registrar and hosting provider.
In short
- The developer does not collect, receive, store, sell or share any of your data.
- No account, no analytics, no tracking.
- Lookups go directly from your browser to public information services.
What the extension accesses
- The current tab's URL, only when you click the extension icon. It is used to decide which domain to scan and is shown to you in the results.
- Domains you type in to scan.
What is sent, and to whom
To perform a scan, the extension sends the domain name (and, for hosting lookups, the domain's IP address) to the public services below. It does not send the full page URL, your identity or any browsing history.
| Purpose | Service |
|---|---|
| Domain registration (RDAP / WHOIS) | IANA data.iana.orgThe domain's registry and registrar RDAP servers rdap.org fallback |
| Registration data for domains without RDAP | NIC Uruguay public lookup dns2-edge.sva.antel.com.uywho-dat WHOIS service who-dat.as93.net |
| IP address ownership | ARIN and the regional internet registries (RIPE NCC, APNIC, LACNIC, AFRINIC) rdap.org fallback |
| DNS records | Google Public DNS dns.googleCloudflare DNS cloudflare-dns.com |
| SSL certificates | Cert Spotter api.certspotter.comcrt.sh crt.sh |
| Hosting network and location | ipwho.is ipwho.is |
| HTTP status, page title, redirects | The website being scanned |
These services receive each request directly from your browser, as with any web request, and handle it under their own privacy policies.
What is stored on your device
The extension uses Chrome's local extension storage for:
- your view preference (Normal or Detailed),
- the most recent scan result, so it reappears when you reopen the popup,
- a temporary cache of lookup results — 24 hours for registration and hosting data, 6 hours for SSL data — deleted automatically when it expires.
This data never leaves your device. Clear it at any time with the Clear button in the extension, or by removing the extension.
Network monitoring
The extension uses Chrome's webRequest permission only to observe its own request to the website being scanned, in order to record redirects and the connected IP address. It does not monitor, block or modify your browsing.
Abuse reports
When you click Report, the extension opens your email program with a pre-filled message. Nothing is sent unless you send that email yourself.
