Privacy

This page describes the calculator’s current implementation. Updated September 28, 2026.

Calculator inputs

Calculations run in your browser. The calculator does not send your measurements or temperature entries to our server or merchants. Our code does not save them in cookies or browser storage.

Website requests

Loading a website sends technical information such as your IP address and browser information to the hosting provider. Hosting and security services may process request logs to deliver and protect the site. The calculator itself has no visitor analytics, advertising scripts, account system, or contact form.

This website uses Cloudflare for hosting and security. See Cloudflare’s privacy policy for its data practices.

Email you send

If you email us, your address, message, and any attachments are processed by the email services used to deliver and receive the message. We use correspondence to respond to inquiries and assess corrections. Messages sent to the contact address are handled by the email providers used by the site operator. Email forwarding is separate from the website; the calculator does not collect your email address.

To request deletion of correspondence, email [email protected]. Identify the message involved without sending additional sensitive information.

External links

Merchant sites apply their own privacy practices when you visit them. Calculator inputs are not attached to product links. Most kit links go to Amazon.com and carry our Associates tracking tag; when you click one, Amazon sets its own tracking cookie, not ours, so it can credit this site with a commission if you buy something afterward. We never see your order details. See the affiliate disclosure for which links this applies to.

Changes

If we add analytics, advertising, forms, or further affiliate programs, we will revise this notice to reflect how those features handle information.
