We use as few cookies as we can get away with. Here’s the full list and how to control them.
Cookies are small text files a website stores on your device. They help sites remember your preferences and understand how the site is used. Some are essential; others are optional.
We keep our cookie use minimal. We use cookies to make the site work, remember basic preferences, and measure traffic in aggregate so we can improve our courses. We do not use cookies to build advertising profiles or track you across other websites.
| Type | Purpose | Optional? |
|---|---|---|
| Essential | Core site functionality and security. | No |
| Preferences | Remember small choices, like dismissing a notice. | Yes |
| Analytics | Aggregate traffic measurement via Google Analytics. | Yes |
Some cookies are set by services we use, such as Google Analytics (for traffic measurement) and embedded video players (when you play a lesson video). These providers have their own privacy and cookie policies, which we encourage you to review.
If our cookie use changes, we'll update this page and the "Last updated" date above.
