Privacy: local calculator & external services

Information entered on the site

There are no website accounts, chat prompts, payment flows, upload controls, contact forms or email subscriptions. Calculator values are processed in browser memory and are not sent to a server or saved in cookies/local storage. Reloading resets them.

“Copy code” uses your browser’s clipboard API only after you click it. The site does not read clipboard contents.

Cookies and analytics

This site uses Google Analytics 4 (measurement ID G-1009PQK2VD) to understand visits and usage. The Google tag loads from googletagmanager.com and sends analytics data to Google. This can include page URLs and titles, referrers, browser/device information and interactions collected by the property’s default settings. Google Analytics uses first-party cookies, including _ga and _ga_* identifiers, to distinguish visitors and sessions. The calculator code does not send its entered values to Analytics. No custom analytics events have been added.

This website is publicly hosted on Cloudflare Pages and requires no site sign-in. Cloudflare may process request information and apply security measures independently of the static site code. No Cloudflare Web Analytics beacon is installed by this site.

Analytics behavior, enhanced measurement and retention depend on the publisher’s GA4 property settings. A specific retention period has not been verified. See Google’s privacy policy and Google Analytics cookie documentation. Browser privacy settings or extensions may block analytics requests; essential site features work without the Google tag.

Hosting request data

When loading a page, the hosting infrastructure receives ordinary request information such as IP address, requested path, browser headers and timing. The site has no custom log database or visitor export. Hosting retention and infrastructure controls are managed by the hosting provider; an exact retention period has not been verified here.

External links

Following a Studio, documentation or other source link leaves this site. That destination may use cookies, accounts, billing or different data-processing rules. Inputs submitted there are governed by that provider, not this local calculator.

The site does not receive prompts or account details from those services.

This statement describes the static code and public Cloudflare Pages deployment as of October 8, 2026. This edition includes Google Analytics 4.
