Privacy

Last updated October 24, 2026

The short version: you don’t need an account, we don’t use cookies to track you, we don’t run ads or analytics, and we don’t sell or share personal information.

What we collect

When you download a worksheet, we record which worksheet it was, the paper size, and the time. We use this only to count downloads, for example to show the most popular worksheets. It isn’t linked to you: we don’t record your name, email address, or an ID for your browser.

Cookies and browser storage

DeltaWorksheets doesn’t set cookies for visitors and doesn’t store anything in your browser. (The only cookie on the site is a sign-in cookie for the site’s administrators.)

Services we use

Like any website, ours runs on other companies’ infrastructure. They process technical information, such as your IP address and browser type, in order to deliver pages and files and to protect against abuse, and they may keep standard server logs:

  • Vercel hosts the website.
  • Cloudflare stores and delivers the worksheet files and preview images.
  • Supabase hosts the database of worksheets and download counts.

Children

DeltaWorksheets is meant for parents, teachers, and other adults choosing worksheets. We don’t knowingly collect personal information from anyone, including children.

Changes

If we add features that collect more information, such as accounts or a newsletter, we’ll update this page before they go live and change the date above.
