Your network inputs belong to you. The calculators run locally in your browser.

Network calculations

IP addresses, subnet plans and transfer values stay in your browser and are not uploaded to a calculation server.

Storage

We use localStorage only to remember your language and theme preferences. You can clear them in your browser settings.

Analytics and cookies

There are no visitor-tracking analytics, advertising scripts or tracking cookies. Your hosting provider may keep ordinary access logs.

Third-party services

Website assets are served from this domain, without required external APIs. Loading the site does contact the hosting server.
