Your inputs stay
in this browser tab.

The calculator does not send entered values to an application server, add them to URLs or automatically save them in browser storage.

Local results and exports

Refreshing restores the example. Copying uses the clipboard after you choose Copy. File downloads are created locally from the current result, and printing uses the browser's print function. Your device and any service you share a plan with then handle that copy under their own settings.

Hosting

This static site is prepared for Cloudflare Pages. Ordinary web requests can contain your IP address, browser details, requested page and request time. Cloudflare may process technical information to deliver and protect the page. See Cloudflare's privacy policy.

Cloudflare Web Analytics

Cloudflare Web Analytics is enabled in this site's hosting settings. Cloudflare Pages adds its measurement beacon on deployment. When that beacon loads, it collects page-view and page-performance information for aggregate website reports. Blocked scripts or failed beacon requests can prevent measurement, so reports may be incomplete.

The calculator's own code does not attach the measurements you enter or its results to analytics events. Visits and page views are not counts of unique people or proof of organic search traffic. Hosting and security requests are separate from these reports; this notice does not claim that infrastructure providers keep no logs. Read Cloudflare's Web Analytics explanation and Cloudflare's privacy policy.

Advertising

Publisher metadata and ads.txt identify the intended Google publisher account. They do not deliver advertisements or establish approval or earnings. No advertising delivery or consent-message script is active in this release. Advertising and consent settings from another website do not automatically apply to this host; its notice must reflect any later service configuration.

Contact correspondence

The public email paperroll.cytoplast640@aleeas.com is an existing shared portfolio forwarding address, also used by Paperroll. SimpleLogin forwards messages to the owner's mailbox. Emailing shares your sender address, message metadata and contents with the forwarding and mailbox services. The owner uses correspondence to address enquiries, corrections and privacy requests. Avoid unnecessary personal details. See SimpleLogin's privacy policy.

External links

Other sites have their own privacy practices. Calculator inputs are not added to external links. Contact the shared inbox about this notice or messages you have sent.
