Site storage
Cookies, local storage and session storage support authentication, security, language and appearance preferences, navigation and signup flows. A public-stream access cookie lasts up to four hours. Local preferences may remain until changed or cleared. These functions do not subscribe you to marketing.
External video
YouTube and Vimeo lesson players load after you choose to allow them. The provider may receive your IP address, device and viewing information and use its own storage. You can stop the player with the on-page control; reloading resets permission. Declining does not prevent access to unrelated features.
Usage measurement and contests
We use cookieless analytics to measure site usage. The embedded contest service uses browser storage to keep your contest session and preferences working and receives connection information when you open it. These features are separate from email open and click tracking, which is described in the Privacy Policy.
Your controls
You can remove site storage through your browser, which may sign you out or reset preferences. Continued browsing is not treated as consent to optional tracking. The Privacy Policy explains other processing and your rights; email preferences are managed separately.
