Most tools run entirely in your browser — the data you paste never leaves your device.
Live checks
For live checks we send the domain or URL you enter to our server, which fetches it. We keep an anonymous log (tool, target, time, hashed IP) for 30 days to prevent abuse.
Contact forms
If you write to us, we keep your name, email and message to reply. Ask us to delete them at any time: [email protected].
Cookies and analytics
We don't set cookies and don't use third-party analytics or ad pixels.
Website data
Statistics are based on public homepages, DNS and robots.txt files of popular websites. We publish aggregates and technology lists, not personal data.
