Updated October 14, 2026. This describes the current free launch version.

What the app stores

Clock preferences — timezone, language, design, mode and configured timer duration — are saved in local storage in your browser. Stopwatch progress and countdown state are saved in session storage for this browser tab. These app values are not sent to an application database.

What is not enabled

This version has no application analytics SDK, payment form, mailing list or user account. It embeds a Coupang product advertising iframe on tool and game pages. It does not ask for GPS location; the default timezone comes from your device settings. The hosting provider may process request information to deliver and secure the site under its own policies.

Coupang affiliate links

Some pages contain clearly labelled Coupang affiliate advertisements. We may receive a commission when you purchase through these links. This site uses external affiliate links and a product advertisement iframe loaded from ads-partners.coupang.com. Loading the banner sends a request to Coupang, which may process request information and use cookies or similar technologies under its own policies. Product selection is configured as home interior category best sellers. There is no automatic page redirect. Clicking a product opens Coupang.

Google AdSense review

This site is being submitted for Google AdSense review. The account verification meta tag and ads.txt file do not themselves load Google advertisements or advertising cookies. Google ads are not enabled in this version. Before enabling Google ads, we will update this notice with advertising providers, cookie use and applicable consent controls.

Shared links

A shared link contains the theme, country, language and mode you selected. Anyone with the link can read those values. It does not contain your current stopwatch result or personal account information.

Delete local data

Clear this site's storage in your browser settings to remove saved preferences. Closing the tab ends the tab-specific storage according to your browser's session behavior.

Before ads or subscriptions launch

This page will be updated with the operator's contact details, providers, processing purposes and applicable consent options before advertising or payment systems are enabled.
