What we store on our server
If you join the daily leaderboard, you choose a display name. For that feature we store:
- Your display name — chosen freely by you; please do not use your real name.
- Your XP score for the current day and the language version you played on.
- A hashed token that ties your browser to your name for the day, so nobody else can submit scores under it. The token itself is stored only on your device; our server keeps a one-way hash.
- A one-way hash of your IP address, kept solely to limit abuse (rate limiting and spam protection). We never store your raw IP address, and the hash cannot be reversed into it.
Leaderboard entries are keyed to a single UTC day and are deleted automatically within 7 days. If you never join the leaderboard, our server stores nothing about you.
What stays on your device
Your game progress — XP total, level, completed chapters, chip balance, chosen name and language — is saved in your browser's localStorage. It never leaves your device except as described above. You can erase it at any time by clearing your browser's site data for howtoplayblackjack.info.
Cookies, analytics and third parties
This site sets no cookies, runs no analytics or advertising scripts, and embeds no third-party content. Fonts, images and game code are served from this domain. We do not sell, share or transfer any data to third parties.
Server logs
Like virtually every website, our hosting infrastructure keeps short-lived technical access logs (requested URL, timestamp, browser user-agent) for security and troubleshooting. These are rotated and deleted on a regular schedule and are not used to profile visitors.
Children
This site teaches the rules and mathematics of a card game and does not offer real-money play. We do not knowingly collect personal information from children; the leaderboard stores only a self-chosen display name and a score.
Your choices
You can play the entire game without joining the leaderboard. To remove a leaderboard entry before its automatic deletion, or for any other privacy question, email [email protected] with the display name and date, and we will delete it.
Changes to this policy
If the site gains new features that change what data is processed, this page will be updated before those features go live. The date at the top reflects the latest revision.
