Privacy

Short version: this site collects as little as technically possible, and nothing that identifies you.

What we do not collect

No accounts, no cookies for tracking, no ad pixels, no fingerprinting. The trainer and simulator store your streak, sound and hint preferences in your own browser’s localStorage — that data never leaves your device.

What is technically logged

Our web server keeps standard access logs (IP address, requested URL, user agent) for security and debugging, rotated automatically. When you click a bonus link, our redirect records the click’s country code, browser language, and which button was clicked — not your IP and nothing personal — purely to understand which placements are useful.

External links

Links marked as bonus offers are affiliate links: if you sign up at a casino through them, we may earn a commission at no cost to you. Casinos are independent businesses with their own privacy policies and terms; from the moment you leave this site, theirs apply. All such links are marked rel="sponsored".

Responsible play

This site is for adults (18+) and exists to teach the mathematics of blackjack. If gambling stops being entertainment, free confidential help exists: BeGambleAware and Gambling Therapy.
