Privacy
BallPark is built to be played without an account. We collect as little as we can to run the daily game.
What we store on our server
- A random player ID kept in a cookie on your device. We store only a one-way hash of it — it isn't linked to your name, email, or any account.
- Your guesses for today's game, the results they produced, and your run total.
- Anonymous totals across all players, used to show percentiles.
We use that data to resume your game if you refresh, stop a guess from being counted twice, and compare scores.
What stays on your device
Your streaks and recent results are saved in your browser's local storage. Clearing your browser data removes them. They never leave your device unless you choose to share your results.
What we don't do
- No sign-up, no email collection, no advertising trackers, no device fingerprinting.
- We don't sell or share personal data.
Sharing
The share button creates a spoiler-free summary (your outcomes and runs). Nothing is posted anywhere unless you send it yourself.
Questions
Every answer comes from a published source, shown after you guess. If you spot an error, please let us know.
