Privacy Policy

Measurement data

The count and timing of your clicks and key presses are calculated only by JavaScript in your browser. They are never sent to a server, and we don't collect which keys you pressed.

Browser storage

Only your theme, last selected duration and input method, best score per mode and last 20 runs are saved in this device's localStorage. You can delete them at any time with the “Clear records” button or in your browser settings.

Shared links

A URL created with “Copy link” contains only the duration, input method and average CPS. When someone opens the link, those values are simply displayed on the page and are not stored anywhere.

Ads and cookies

Kakao AdFit ads may be shown to help keep the site running. The ad provider may use its own cookies or similar technologies to serve and measure ads, which are governed by that provider's privacy policy.

Offline cache

For faster repeat visits, a service worker caches only static files such as stylesheets and scripts. Measurement data is never cached.
