Privacy & Data

Last updated: May 18, 2026.

Short version

Urordle is a small, single-page web game. We don't run a server that stores your data, we don't have user accounts, and we don't sell, share, or transmit anything about you to anyone. The only thing the app remembers is what your own browser saves locally.

What we store locally on your device

We use your browser's localStorage (not cookies) to remember:

• Whether you've completed today's puzzle and how many guesses it took
• Your current and longest streak
• A guess-distribution histogram
• A per-day history (which past puzzles you've solved) so the Archive can show your results
• A flag noting that you've seen the "How to play" modal so we don't reopen it

This data never leaves your device. It is not sent to any server we control or to any third party. You can wipe it any time from Statistics → Reset stats, or by clearing site data in your browser settings.

Cookies

Urordle sets no cookies. None. The localStorage entries above are the only data the app writes.

Analytics & tracking

Urordle includes no analytics, no pixels, no fingerprinting, and no third-party scripts that observe your activity. Your visit is not logged beyond standard server access logs maintained by our static host (Cloudflare Pages), which Cloudflare retains for security and abuse-prevention purposes per their privacy policy.

Third-party services

The site is hosted on Cloudflare Pages and served through Cloudflare's CDN. Cloudflare sees standard HTTP request metadata (IP address, user agent, requested URL) but Urordle does not pass them any data about you.

Service worker / offline use

We register a service worker so Urordle can run when you're offline. It caches the app's static files (HTML, CSS, JS, icons) on your device. The service worker does not collect or transmit data.

Children

Urordle is intended for adult medical learners. It is not directed at children under 13. We do not knowingly collect data from any user — including children — because we do not collect data from users at all.

Medical disclaimer

Urordle is for education and entertainment only. The cases, diagnoses, workups, and treatments shown are simplified for the puzzle format. Nothing in this app is medical advice or clinical decision support. Always defer to current guidelines, institutional protocols, and your supervising clinicians for patient care.

Changes

If this policy changes, the "Last updated" date above will change with it. Material changes will be noted in the site footer for a reasonable period.
