Privacy
The short version: the site has no accounts, sets no cookies of its own and runs no analytics script.
Last updated 14 November 2026.
What the site collects
Nothing that identifies you. There is no sign-up, no contact form and no comment box. The worksheet generator and the fillable chart run in your browser; what you type or choose is not sent anywhere and is not stored.
Hosting
The site is served by Cloudflare. Like any web host, Cloudflare processes the technical details of each request, such as IP address, browser type and the page requested, to deliver the page and to protect against abuse. See Cloudflare's privacy policy.
Search engines
The site uses Google Search Console and Bing Webmaster Tools, which report how pages appear in search results in aggregate. They do not place anything on your device.
Advertising
The site does not show ads at present. If it later does, this page will be updated first to name the advertising network and explain what it collects and how to opt out.
Children
The site is written for teachers and parents and does not knowingly collect personal information from anyone, including children.
Changes
If this policy changes, the date at the top of the page changes with it.
