Privacy
Short version: Mathness! Math Worksheets doesn't collect personal information. There are no accounts, sign-ups, ads or cookies, and nothing follows you from visit to visit or across other sites. We count page visits, without cookies, to see which sheets help people.
What stays in your browser
The site remembers a few things in your browser's local storage, on your own device: sheets you save, your print settings (colour, paper size, "why" lines), your standards choice and light or dark mode. They are never sent to us or anyone else. Remove a saved sheet with its Remove button, or clear everything by clearing this site's data in your browser.
Visit counts
To learn which pages are useful, the site uses Cloudflare Web Analytics. It counts page views and notes the page that sent you here (a search engine or Pinterest, say) and broad details like your country, the kind of device and how fast the page loaded. It sets no cookies, stores nothing on your device, and doesn't recognise you on your next visit or follow you to other sites. A small script from Cloudflare (cloudflareinsights.com) does the counting.
Hosting
The site is served by Cloudflare Pages. Like any web host, Cloudflare handles technical details such as your IP address and browser type to deliver the pages and protect the site, as described in Cloudflare's privacy policy. We don't use that information to identify anyone. Fonts and pictures come from the site itself; the only other request is Cloudflare's visit counter above.
Children
The site is made for teachers and parents. It collects no personal information from anyone, children included. Names go on the printed paper, not into the site.
If you write to support@zubin.dev, your message and address are used only to reply and to fix what you report. "Report a problem" opens your own email app with a message already filled in: the page's link, the sheet's code, your browser's name and your screen size, so we can see the same sheet. You can read and change all of it before you send, and nothing is sent unless you do. The share buttons (Pinterest, Facebook, X) are plain links: those sites hear nothing from this one unless you click them.
Changes

This page is about the worksheets site. The Mathness! app for iPhone and iPad has its own privacy policy.
