What we collect

Nothing that identifies you. There are no accounts and no forms, and Chalkline Math doesn't set cookies. Every calculation runs in your browser, and the numbers you type are never sent to us.

Third parties

• Hosting. The site is served by Cloudflare, which processes standard request data (such as your IP address and browser type) to deliver pages and protect against abuse.
• Fonts. Fonts load from Google Fonts, so your browser connects to Google's servers. See Google's privacy policy.

Changes

If we add analytics or advertising in the future, we'll update this page before doing so and explain what is collected and how to opt out.
