Privacy
Last updated November 10, 2026
Certified Ball Knower is a free, fan-made sports games site. The short version: there are no accounts, no cookies and no tracking. We don't collect your name, email or anything else about you.
What's saved, and where
Your streak, scores, badges and settings (sound and light or dark theme) are saved in your own browser using local storage. This information stays on your device and is never sent to us. Clearing your browser's site data for this site erases it, and so does using a private window.
Cookies
This site doesn't set any cookies.
Things we don't do
- No accounts or sign-ups.
- No analytics, tracking pixels or ad trackers.
- No selling or sharing of personal information. We don't have any to share.
Hosting
Like every website, our hosting provider (Vercel) receives standard technical information when your browser loads a page, such as your IP address and browser type. It uses this to deliver the site and protect it from abuse, and keeps it only briefly. Fonts, photos and logos are bundled with this site, so loading a page doesn't contact any other company.
Links to other sites
Photo credits link to Wikimedia Commons, and the Share button uses your device's own share sheet or clipboard. Other sites you visit from here have their own privacy policies.
Kids
Anyone can play. Because we don't collect personal information, we don't knowingly collect any from children under 13.
Changes and questions
If this policy changes, the new version will be posted here with a new date. Questions? Email privacy@certifiedballknower.com.
