We use Google Analytics, PostHog, and Meta Pixel to understand how this site is used and to measure the effectiveness of our advertising. That helps us see which math topics are most popular, where people are having issues, and which outreach efforts are actually bringing teachers to the site. We do not sell your personal information to data brokers or third parties, but privacy laws still require us to give you a way to opt out of this analytics and advertising tracking.
