What we collect

Only your email address, and only if you sign up for updates. We don't use accounts, and the site doesn't ask for anything else.

How we use it

Your email is stored with Kit (kit.com), the service that sends STEM Dad emails. We use it only to send you new projects and STEM Dad news. We never sell or share it.

Unsubscribing

Every email has an unsubscribe link. To have your address deleted completely, email hello@thestemdad.com.

Kids

This site is meant for parents and other adults. If you're under 13, please ask a grown-up to sign up for you. We don't knowingly collect information from children under 13.

Visitor counts

We count visits with Cloudflare Web Analytics, which doesn't use cookies or follow you to other sites.

The reaction game

Your best time is saved only in your own browser. It never leaves your device.
