Privacy policy

KalviBooks is built to collect as little as possible. You never need an account to use it.

What we collect

• Analytics. We use Google Analytics 4 and Cloudflare Web Analytics to count page views and see which pages help students. These tools record things like the page visited, the device type and an approximate location (city level). We do not use them to identify you.
• Email signup (optional). If you give us your email address, we use it only to send KalviBooks updates. You can unsubscribe from any email.
• Quiz scores. Practice-quiz scores are kept only in your own browser (local storage). They are never sent to us.

Videos

Answer pages show a YouTube thumbnail. Nothing is loaded from YouTube until you press play; after that, YouTube's own privacy policy applies to the video.
