Privacy
How this static site, its host and reader email handle information.
What we collect
The website has no analytics, cookies, accounts or submission forms. If you email the editor, the message and your return address are received through email, outside this website.
Calculators
Calculator inputs are processed in your browser and are never sent to a server, placed in a web address, stored on your device or written to any log. Closing the page discards them. There is no “save” function; if one is added later it will be opt-in and will say plainly that another person using the same device could read what you saved.
Third parties
Every asset on this site — including fonts — is served from the site itself. Loading a page makes no request to any third party.
Hosting
The site is hosted as static files by Vercel. The host processes ordinary request information, which can include an IP address, requested URL and browser details, to deliver and secure the site. The site operator may have access to limited hosting logs. Do not put personal or calculator information in a page URL.
Owner records
Owner accounts are submitted through a separate private record on its own host, with its own privacy notice covering what is stored, who reviews it, what becomes public only with your approval of the exact version, and how to withdraw. Nothing entered there touches this site.
