Privacy notice

Current site version: No advertising or third-party analytics scripts are installed. Quiz best scores are saved in your browser’s local storage; the shared leaderboard receives a pseudonymous browser identifier and quiz answers when you start and complete a daily quiz, if the leaderboard backend is enabled. It calculates a score on the server. Only if you choose to post do we display your nickname, score and quiz date publicly. If you choose to post, we store your nickname (1–5 letters), score, UTC quiz date, a random browser identifier and a server-side attempt record in Cloudflare D1. Other visitors can see the nickname, score and date. The browser identifier is not displayed. You can play without posting. Clearing browser data removes your local identifier but does not erase a posted score; contact the site operator to request removal. We use this information only to operate and limit abuse of the leaderboard. Scores may be retained until you request removal or the leaderboard is discontinued. You can remove them by clearing site data in your browser.

Cloudflare hosts the site and may process technical request data such as IP addresses to deliver and secure it. Refer to Cloudflare’s privacy policy for its practices.

We do not provide user accounts or a newsletter. If advertising or analytics are added later, this notice and any required consent choices must be updated before activation.

Site operator/contact: Add verified operator and contact details before advertising or a wider public launch. See Contact.
