What We Collect
When you create an account, we collect your email address and chosen username. If you opt in during signup, we add you to our newsletter list. We also store your quiz progress (correct answers, missed questions, favorites) to power the adaptive learning features.
How We Use It
Your data is used solely to provide the service — tracking your progress, showing your leaderboard rank, and (if you opted in) sending occasional updates about new features. We do not sell your data. Ever.
Cookies & Analytics
We use Google Analytics to understand how people use the site (pages visited, session length, etc.) and Google AdSense to display ads. These services may use cookies. You can opt out via your browser settings or browser extensions.
Email List
If you signed up for our email list, you can unsubscribe at any time using the link at the bottom of any email we send.
Your Data
You can delete your account and all associated data at any time by contacting us. Guest play (no account) stores nothing on our servers.
