Privacy Policy

Last updated: September 2026

The short version

You can play every game without an account, and we do not collect anything that identifies you. Your scores, review deck and settings are stored in your own browser's local storage and never uploaded. We use Google Analytics to count visits and see which pages are useful — it collects only anonymized, aggregate traffic data.

Data stored on your device

Local scores: your best score per game/topic combination.
Review deck: words you missed, with their definitions and review dates.
Sound preference: whether the 8-bit sound effects are on or off.

All of this lives in localStorage on the device you are using. Clearing your browser data removes it permanently. Nothing here is transmitted to our servers — there are no servers.

Google Analytics

This site uses Google Analytics 4 to understand aggregate usage (page views, approximate country, device type). Google Analytics uses cookies and may process this data per its own privacy policy. You can block analytics cookies in your browser settings; blocking them does not affect gameplay in any way. We never link analytics data to a personal identity.

If advertising is added in the future, third-party ad networks (such as Google AdSense) may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising at adssettings.google.com or via aboutads.info.

Children

The site is educational and welcomes classroom use. Because we do not collect personal data or require accounts, no special registration exists for children — and no personal information is requested from any visitor, of any age.
