Privacy Policy
A static reference site, so the list of what we collect is short.
The short version
There is nothing to sign up for here. No account system, newsletter form or comment box exists on this site, so we do not hold a database of visitors. The reading sorter, deadline calculator, capsule arithmetic and inspection checklist do their work inside the page in your own browser; the numbers you type are not transmitted to us or stored. The one exception is email: if you write to us, your address and message sit in our inbox and are used to answer you.
Like any web host, ours records routine technical logs such as IP address, browser type and the pages requested, which are used to keep the site running and secure.
Asking about your data
If you live in California, or anywhere privacy law gives you access and deletion rights, you can ask what we hold about you and have it removed. In practice that means any email you sent us. Write to [email protected]. We never sell personal information and do not share it with advertisers.
Updates to this policy
Any change in how we handle information will be posted on this page with a new date. Current version: October 19, 2026.
