Privacy Policy

The short version

Subneter is a calculator that runs entirely in your browser. We don't have a server-side database, and we don't ask you to create an account. We don't collect the IP addresses or subnet data you type into the calculator — that math happens locally on your device and is never sent anywhere.

What data is collected

Like most websites, we use a small number of third-party services that may collect limited technical data automatically:

• Google Analytics — collects anonymized usage data (pages visited, approximate location by country/city, device type, referring site) to help us understand how the site is used.
• Google AdSense — may use cookies to show relevant ads. Google may use this data in line with its own privacy policy. You can control ad personalization at adssettings.google.com.

What we don't do

• We don't store the IP addresses, subnets, or hostnames you enter into the calculator.
• We don't require sign-up, login, or any personal information to use the tool.
• We don't sell any data to third parties.

Cookies

This site may set cookies through Google Analytics and Google AdSense, used for the purposes described above. You can disable cookies through your browser settings at any time; the calculator itself will continue to work normally without them.
