Current build: IPv4 and IPv6 inputs, results and allocation plans remain inside the browser.
No analytics provider, advertising provider, account system, contact form or server-side tool API is configured. Static hosting may produce infrastructure logs under the hosting provider's terms; retention and access must be documented before launch.
The current plan exists only in page memory. It is not added to the URL, written to local or session storage, or included in logs, analytics or telemetry. Markdown and JSON exports are written only to the clipboard when requested. Reloading the page starts with an empty calculator.
Future optional services
Analytics events may count page views, calculations, validation categories and copied field names. They must never contain the entered address, CIDR, calculated range, allocation state or free-form text. Advertising cannot activate until account, consent, privacy and placement gates pass.
Your choices
Optional categories default off. The calculator's Privacy choices control clears any local optional preference. A certified consent platform will replace this local placeholder before advertising is enabled where required.
