When you use the Subnet Calculator, the IP addresses and prefixes you enter are processed by our server to generate your results. We do not log, store, or archive the addresses you calculate. Once the calculation is complete and the page is sent to your browser, that data is cleared from the server's temporary memory.
This website uses basic session cookies to remember your current mode (IPv4, IPv6, VLSM, etc.) and to protect against CSRF attacks. We do not use tracking cookies or third-party advertising trackers that follow you across the web.
When you generate a CSV or JSON export, the file is created and streamed directly to your browser via PHP. No copy of your network plan is kept on our server disks after the download is initiated.
If we provide links to external resources (like network documentation), we are not responsible for the privacy practices of those third-party sites.
We may update this policy occasionally. Any changes will be posted on this page with an updated timestamp.
