Privacy policy
Last updated:
Blurdle is a free daily puzzle made by Adam Young. This page explains what information is collected when you play, who it’s shared with, and the choices you have. In short: there are no accounts, your game data stays on your device, and the site uses a few third-party services for analytics, advertising and error reporting.
Your game data
Your guesses, results, streaks, statistics and achievements are stored only in your browser’s local storage. They’re never sent to an account, because there are no accounts. When you make a guess, it’s sent to the Blurdle server to be checked, but it isn’t stored there or linked to you.
You can delete your game data at any time by clearing this site’s data in your browser settings. That will also reset your streak, and it can’t be recovered.
Google Analytics
Blurdle uses Google Analytics to understand how many people play, which pages they visit and roughly where they are in the world. Google Analytics uses cookies and collects information such as your browser, device, approximate location and the pages you view. Blurdle also records game events, such as finishing a puzzle, without any personal details. This information is processed by Google under Google’s privacy policy. You can opt out using the Google Analytics opt-out browser add-on.
Google AdSense
Blurdle is kept free by showing ads through Google AdSense. Google and its advertising partners use cookies and similar technologies to serve ads, to measure how they perform, and, where you allow it, to show ads based on your previous visits to this and other websites (personalised ads).
You can read how Google uses information from sites or apps that use its services. You can turn off personalised ads from Google at any time in Google’s Ads Settings, and opt out of some third-party vendors’ use of cookies for personalised advertising at aboutads.info. If you turn personalised ads off, you’ll still see ads, but they’ll be less relevant.
Consent in the UK, EEA and Switzerland
If you visit from the UK, the European Economic Area or Switzerland, Google’s consent message asks for your choices before any advertising or analytics cookies are set. Until you choose, Google Analytics and AdSense run in a restricted mode that doesn’t use cookies for analytics or ad personalisation. You can change your choices at any time through the privacy and cookie settings link that Google’s message adds to the page.
Vercel
Blurdle is hosted on Vercel, which processes server logs (including IP addresses) to run and protect the service. It also uses Vercel Web Analytics to count page views. Vercel Web Analytics doesn’t use cookies and doesn’t track you across sites; visitors are counted using a hash that changes daily. See Vercel’s privacy policy.
Sentry
If something breaks, an error report is sent to Sentry so the bug can be found and fixed. Reports include technical details such as the error message, the page, and your browser and operating system. They don’t include your game history. See Sentry’s privacy policy.
Children
Blurdle is suitable for all ages but isn’t directed at children under 13, and it doesn’t knowingly collect personal information from them.
Your rights
Depending on where you live, including under UK and EU data protection law, you may have the right to access, correct or delete personal data held about you, or to object to how it’s used. Blurdle itself holds no personal data about you beyond short-lived server logs; for data held by Google, Vercel or Sentry, the links above explain how to exercise your rights with them.
