How do I allow cookies from Khan Academy?

An HTTP cookie is a small amount of text that helps a website track information about a user across multiple pages of the website, and personalize the user's experience on the website. Khan Academy uses cookies to better display our website, to save you time, to provide better technical support, for promotional purposes, and to track website usage. For example, cookies help us to:

1. Keep track of whether you are signed in or have previously signed in so that we can display all the features that are available to you.
2. Remember your settings on the pages you visit, so that we can display your preferred content the next time you visit.
3. Customize the function and appearance of the pages you visit based on information relating to your account; for example, in order to default you to a particular study level, or to remember customized settings for a report.

Some features and services on Khan Academy (particularly those that require you to sign-in) may not function properly if cookies are disabled or blocked in your browser.

If you find that your browser is blocked from accepting cookies at a school or district level, you may need to talk to a network administrator about whitelisting domains (see this article).
