You can play without signing in or providing an email address. We do not add advertising, analytics trackers or third-party font requests.
Your browser and your round
LocalStorage keeps your anonymous round identifier and a cached copy of your progress on this device. The server stores the round’s prompts, results, attempts and timer deadline so that answers and scores can be checked consistently. Changing devices or clearing browser storage can make a round inaccessible.
Daily round records expire after the following UTC day. Practice rounds expire after two hours. Expired records are deleted during scheduled maintenance. These identifiers are not player accounts; they do not sync between domains or devices.
Correction reports
If you submit a correction, we store the prompt, answer, public source link and explanation for up to 90 days. Reports receive an anonymous reference number. We do not ask for an email address, and submitting the form does not send an email. Avoid adding personal or sensitive information.
Sharing a result
Copying a result puts its text on your clipboard. Saving a share image downloads a PNG of your score and result squares. A share card does not contain accepted answer names. Footbillion does not publish a post or message on your behalf.
Hosting requests
The hosting service processes requests needed to deliver the site and may keep standard operational logs, such as request times and network information. We do not use those logs to build a player profile.
