Calculations stay
in your browser.

The calculator does not submit input values to an application server, append them to URLs or automatically save them in browser storage.

Your results and exports

Inputs remain in this tab until changed or refreshed. Copying uses the device clipboard only when you choose Copy. Downloads create a file locally from the current result. Printing uses the browser's print function. Your device and any service you later share a file with have their own data handling.

Hosting requests

The site is prepared for Cloudflare Pages. Ordinary web requests can contain an IP address, browser details, requested page and time. Cloudflare may process that information to deliver and protect the website. 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 email

The public email cutplan.spinner443@aleeas.com is an existing shared portfolio forwarding address, also used by Cutplan. SimpleLogin forwards correspondence to the owner's mailbox. Sending email shares your address, ordinary message metadata and content with the forwarding and mailbox services. The owner uses messages to handle enquiries, corrections and privacy requests. Avoid unnecessary personal information. See SimpleLogin's privacy policy.

External websites

External links have their own privacy practices. Calculator values are not added to those links. For questions about this notice or correspondence you sent, use the contact page.
