PRIVACY INFORMATION
Your inputs stay in your browser.
Boxmetric performs its calculations on your device. No account, contact form or server-side calculation service is used.
Calculator data
The site does not send the values you enter to its operator. This release does not save inputs in cookies or local storage. Reloading the page restores its illustrative defaults. Copying places a result on your clipboard only after you select Copy. Downloading a CSV creates a file on your device; your browser handles that download.
Hosting and technical requests
Cloudflare Pages delivers these static pages. Like other web hosting, delivery involves technical request information such as an IP address, requested URL, time and browser details. Cloudflare handles that processing under its own policies. Read Cloudflare’s privacy policy for more information.
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.
Email enquiries
The public contact address yardfill.helpful594@aleeas.com is an existing shared portfolio alias. It forwards through SimpleLogin to the operator’s mailbox. Emailing shares your sender address, message and any attachments with the forwarding service and the receiving mailbox. Include only what is needed for your enquiry. Read SimpleLogin’s privacy policy.
Your choices
You can use the calculator without contacting anyone or downloading a file. To ask about an email you have sent or request deletion from the operator’s mailbox, use the same contact address. The operator can address records it controls; hosting and email providers handle their own processing.
Notice updated 18 October 2026. Contact the operator.
