Privacy Policy
This site is intentionally simple. It does not use accounts, a database, or third-party analytics providers.
What this site does
The checker makes a best-effort attempt to read the public-facing IP visible to the server from request headers and compare it with the router WAN IP that you enter manually in your browser.
What this site does not do
This version of the site does not include user accounts, a customer database, a contact form backend, or any third-party analytics provider. The site is designed to be informational and lightweight.
Web Analytics
The site uses Vercel Web Analytics to measure basic page usage in a privacy-friendly way. No additional analytics platforms are installed in this project.
Manual information you enter
The WAN IP field is used only to perform the comparison in your browser. There is no account storage workflow attached to it in V1.5.
