Privacy statement

Which personal data WhoisCheckr processes when you check a domain, and why.

WhoisCheckr is a free tool to check domain names. You do not need an account, and we process as little personal data as possible. This statement explains what we do process and why.

Who is responsible

WhoisCheckr is a product of Aivion Studios. Questions about privacy can be sent through our contact page.

What we process

  • The domain names you check. We store them without any link to you, to show search trends and the history of a domain.
  • Your IP address, briefly, to limit the number of lookups per visitor and keep the service available for everyone. It is kept in a temporary counter for at most one day.
  • The email address you enter when you send a report. We use it only to send that one email and do not keep it afterwards.
  • Technical data that every web server receives, such as browser type and the pages requested, in server logs that are kept for a short time for security.

Why we process it

To answer your lookups, to prevent abuse of the service and of the report email, and to keep the site secure. The legal basis is our legitimate interest in offering a reliable, safe service, and for the report email, your own request.

Data about domain holders

The WHOIS pages show data that the domain registries publish themselves. Registries hide the personal data of private holders; WhoisCheckr shows no more than what the registry makes public. If you think information about you is shown incorrectly, contact the registry or registrar of the domain, or contact us.

Sharing

We do not sell data and do not share your searches with registrars, domain resellers or advertisers. To answer a lookup we send the domain name, and only the domain name, to the registry of its extension. Emails are sent through our email provider.

Your rights

Under the GDPR you can ask us for access to, correction of or deletion of your personal data, and object to processing. Because we do not link searches to people, we usually hold nothing we can trace back to you. You can also file a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
