Privacy

You can play without providing a name, email address, or password.

What the game stores

An essential, HTTP-only cookie called rngdle_session identifies your anonymous browser session for up to one year. The server stores a hash of that identifier, your creation time, Odds Run and Patterns games, actions, scores, and completion dates. It also stores six-digit Badge Rolls with their badge breakdowns, EP totals and roll dates, Daily Rolls, Odds Streak progress, One Edit submissions, collection discoveries and the actual conditional chances of new Patterns draws. These records restore your games, calculate personal summaries and enforce daily limits. Collection entries distinguish natural draws from crafted rerolls.

Your browser’s local storage remembers which revealed round you have seen and any action waiting for a network retry, including Odds Streak and One Edit. One Edit also saves an unsubmitted draft in local storage. Small preference cookies remember your sound setting and the selected prediction, peek picker, and viewed round for each mode. A Patterns preference cookie remembers your locked positions for the current saved board. They let a refreshed page render the same view immediately; they never determine scores or hidden codes. Sound is synthesized on your device after you interact. Clearing cookies or switching browsers prevents us from reconnecting you to the old identity. There is no cross-device account sync.

Installed app and offline files

The site registers a service worker and caches public files such as styles, icons, scripts, installation instructions and game rules. Game pages, API responses and personal results are not stored in this offline cache. Playing and saving moves require an internet connection. Removing the installed app may not clear browser data; your browser’s site settings can remove cached files and cookies.

Hosting and logs

The deployment is designed for Cloudflare Workers and D1. The hosting provider processes network information needed to deliver requests. The app’s error logs omit codes, cookies, action payloads, and personal identifiers. Hosting configuration may retain operational request metadata.

No advertising or analytics trackers

This version includes no third-party advertising or analytics scripts. Fonts and other interface assets are served with the site. Share images are drawn on your device. Only pressing a share control copies text, downloads an image or opens your device’s share dialog. The app does not post on your behalf. Daily Roll cards can include your personal code; shared puzzle cards leave answers out.

Friend challenge links

Creating a challenge publishes your final score to anyone with the link and lets friends play the same puzzle. The link contains a random ID, with no name or email. It shows the host’s score and the number of completed challengers; each friend sees their own result. It does not expose another player’s choices or unrevealed codes.

Keeping and deleting data

Game records are retained to restore progress and provide your history until you delete them using the control below. Deleting your data removes your collection, daily rolls, Badge Rolls and EP, saved streak runs, One Edit answers and draw records as well. It also revokes invitations you created and removes your shared score. Friends who already started keep their own runs and results; their records belong to their anonymous identities. Deleting game data does not immediately remove any operational hosting logs. You can also clear local site data in your browser.
