Privacy, plainly.
What to know when you read, learn and watch with EurekaOh.
Your preferences and progress
Your light or dark theme preference is saved in this browser. Where lesson progress and quiz attempts are available, they are also saved in your browser. They are not synced to another device or a learner account.
You can remove this information by clearing this site’s browser data. Private browsing, browser settings or clearing data may prevent preferences and progress from being kept.
Videos and external websites
Video links take you to YouTube, which has its own privacy practices. If a lesson offers an embedded player, its notice explains when loading that player connects your browser to YouTube. Reading a lesson does not require watching a video.
External websites control the information they collect when you visit them. See Google’s privacy policy for information about YouTube.
Delivering these pages
Our hosting provider processes information needed to deliver web pages, such as network requests and IP addresses. Those requests are separate from the learning progress saved in your browser.
