Privacy

The short version: we collect as little as possible, never sell anything, and don't use ads or trackers.

This website

Browsing mathwithmrdj.com doesn't set cookies or load tracking scripts. Fonts and images, including video thumbnails, come from this site rather than from Google or YouTube. Links to YouTube take you to YouTube, which has its own privacy policy.

The email list

• What we keep: your email address, when you signed up, and the note that you asked for launch news.
• What we send: news about new videos, puzzle features, and free resources from Math With Mr DJ, about once a month.
• Who it's for: parents, teachers, and students 13 and older. Younger students: please ask a parent or teacher to sign up instead.
• Who sees it: only Math With Mr DJ. We never sell or share the list. If we use an email service to send messages, it handles the addresses only to deliver those emails for us.
• Leaving: every email has an unsubscribe link, or unsubscribe here. Your address is deleted right away.

Internet addresses

Like every website, our server sees the internet address (IP address) of each visit. We only use a scrambled version of it to stop bots from flooding the sign-up form, and those records are cleared out automatically, usually within an hour. The site is hosted by Cloudflare, which handles connection data to run and protect the site and keeps short-term logs.

Daily puzzles

The puzzles at puzzles.mathwithmrdj.com have their own privacy page. They need no sign-up and never ask for names, emails, or ages.
