Privacy

Last updated 8 November 2026

The short version

No accounts and no sign-ups. Your course progress stays in your own browser. Course pages show Google ads, and Google uses cookies for them.

Course progress

When you mark a lesson complete, that's saved in your browser's local storage on your device. It's never sent to me. Clearing your browser data removes it.

Ads (Google AdSense)

Course pages show ads from Google AdSense. The home page doesn't. Google and its partners use cookies to show ads based on your visits to this and other websites.

• You can turn off personalised ads in Google Ad Settings.
• Learn how Google uses data: How Google uses information from sites that use its services.
• You can opt out of some third-party ad cookies at aboutads.info.

Visitors in the EEA, the UK and Switzerland are asked for consent before personalised ads are shown.

Feedback

If you send feedback, I get your message and, if you add it, your email address. I only use your email to reply to you.

Links to other sites

Lessons link to free resources on other websites. Their own privacy policies apply there.
