This page explains what information Domain Mechanic uses, for the website and for the browser extension. Last updated: 7 November 2026.

In short

Domain Mechanic does not ask for your name, email address or any account. It has no adverts, no tracking and no analytics. The only thing it needs is the domain you want to check.

What is sent when you check a domain

The domain name you check (for example example.com) is sent to domainmechanic.co.uk. The server looks up that domain's public DNS records and sends the results back to you.

To look up the records, the server asks Cloudflare's public DNS service and some public spam lists (SpamCop, Mailspike, PSBL and UCEPROTECT). These services receive the domain name, or the IP address of the domain's mail server. They do not receive anything about you.

Domain Mechanic does not save the domains you check or the results.

The browser extension

The extension sends a domain to domainmechanic.co.uk only when you click a button:

  • Check: sends the domain you typed.
  • Check the website you are on: sends the domain of the tab you have open (for example bbc.co.uk). It does not send the full web address, the page content or your browsing history.

The extension can only read the current tab after you click its toolbar button. It cannot see your other tabs, and it does not run in the background.

What is stored on your device

The website and the extension store one setting in your browser: whether you chose light mode or dark mode. This setting never leaves your device. No cookies are used.

Hosting

The website runs on Cloudflare. Like any web host, Cloudflare receives your IP address when your browser connects, so that it can send the page back to you. Cloudflare may keep basic technical logs to protect the service from attacks. Domain Mechanic does not use these logs to identify anyone.

Changes to this page

If what Domain Mechanic does with information changes, this page will be updated first, and the date at the top will change.
