Privacy Policy
Last updated: 16 October 2026
Colordle (colordle.org) is a free daily color-guessing game run by an individual developer, Osmanyo, based in France. This page explains what data is involved when you play and what choices you have. For any privacy question or request, email osmyo83@gmail.com.
1. Data stored on your device
Your game progress (guesses for each day, wins), your chosen color list and your settings are saved in your browser's local storage. This stays on your device and is not sent to us. You can erase it at any time by clearing this site's data in your browser. The optional "backup code" in Saved Games is generated on your device and only goes wherever you paste it.
2. Anonymous game statistics
To show community stats (number of winners, average tries, your rank), the game sends anonymous totals to Google Firebase (Cloud Firestore) when you guess and when you win: an increase of the winner count, number of tries, solving time, and the name of the last color guessed. These totals are not linked to your identity, account or device.
3. Feedback form
If you send feedback, we store your message, the email address you enter (optional), your browser's user-agent string (browser and device type, used to reproduce bugs), the puzzle you were on, and the time. This is stored in Google Firebase and used only to read and reply to your feedback. Ask us by email and we will delete it.
4. Analytics
We use Google Analytics to understand how many people visit and which pages they use. Google Analytics uses cookies and collects information such as pages viewed, approximate location (country/city), device and browser type, and how you arrived at the site. We only see aggregated reports, not individual identities. See how Google uses data from sites that use its services.
5. Advertising
Colordle shows ads served by Google AdSense, which help support its development.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You can opt out of personalized advertising in Google's My Ad Center, or opt out of some third-party vendors' cookies at aboutads.info.
- See how Google uses cookies in advertising.
If you are in the European Economic Area, the UK or Switzerland, a consent message (Google's certified consent tool) asks for your choice before advertising cookies are used. You can change your choice at any time:
6. Other services the site loads
To work, pages load code or data from these providers, which receive your IP address as part of any normal web request:
- GitHub Pages: hosts the website.
- esm.sh: delivers the open-source 3D library used by the explorer page.
- Google (gstatic.com, googletagmanager.com, googlesyndication.com): Firebase, Analytics and AdSense code.
- Color Pizza API (api.color.pizza): only if you select an online color list.
7. Legal basis and your rights
Anonymous statistics and storing your progress are needed for the game to work. Feedback is processed because you choose to send it. Analytics and personalized advertising rely on your consent where the law requires it.
Under the GDPR you can ask to access, correct or delete personal data about you, or object to its use, by emailing osmyo83@gmail.com. You can also file a complaint with the French data protection authority, the CNIL.
8. Changes
If this policy changes, the date at the top of this page will be updated.
