How we handle your data

The password generator, the DNS lookup, the CSR, SPF and DMARC generators, the email header analyzer, the name building in the domain name generator, the chmod calculator, the cron generator, the .htaccess generator and the robots.txt builder run in your browser: the CSR private key, the pasted headers and the .htpasswd password, which is hashed right in your browser, are never sent anywhere. The DKIM checker and the reverse DNS lookup also run in your browser and query the public DNS resolvers of Google and Cloudflare over DNS over HTTPS. The website checker and the SMTP test read DNS records the same way.

WHOIS, the domain check, the SSL checker, the IP blacklist check, the hosting checker, the redirect checker, the availability check in the domain name generator, the website checker, the speed test, the is it down check, the DNS propagation checker, the CMS detector, the SMTP test and the live robots.txt check query registries, blacklists, DNS servers, mail servers and sites from our server, with a rate limit and without storing your address. The domain age checker uses the same registry (RDAP) lookup as WHOIS, the speed test measures from our server, and the SMTP test only opens a connection and never sends mail. The domain extensions list simply shows our price table. The tools load no external scripts and show no ads.

When you need hosting

If a check shows a domain is free, you can register it on the domain registration page. For the site itself, RichHost hosting plans start at $8 per month with NVMe disks, free Let’s Encrypt SSL, mail on your own domain and servers in Europe and the USA.
