What we collect

If you subscribe to email updates, we store your email address, the page you subscribed from, and the time you subscribed. That is the only personal data this site collects.

What we do with it

We use your email address to send you new lessons and updates about the curriculum. We do not sell, share, or transfer your email address to anyone.

What we do not collect

Reading progress is stored only in your own browser (localStorage) and never leaves your device. We do not use advertising trackers.

Unsubscribing and data removal

Every email we send includes an unsubscribe link. You can also request removal of your data at any time by emailing [email protected] and we will delete it promptly.

Hosting

This site is served through Cloudflare, which processes standard request logs (IP address, user agent) to deliver and protect the site.
