Last updated: April 8, 2026
This Cookie Policy explains how Clock-Tani (the 'Service') uses cookies and similar technologies on our website. This policy describes the types of cookies used, their purposes, and how you can manage them.
What Are Cookies?
Cookies are small text files stored in your browser when you visit a website. They are used to remember your preferences, improve the service, and deliver relevant content and advertisements. Clock-Tani primarily uses the browser's localStorage instead of server-side cookies to store user settings (theme, alarms, timer state, etc.).
Types of Cookies We Use
Clock-Tani uses the following types of cookies and storage technologies.
1. Essential Cookies (localStorage)
These cookies are necessary for the basic functionality of the service. Without them, the service cannot function properly.
- Theme settings (dark/light mode) storage
- Alarm and timer state storage
- Stopwatch lap time record storage
- World clock city list and order storage
- Cookie consent state storage
- User language preference storage
2. Analytics Cookies (Google Analytics)
We use Google Analytics to analyze service usage patterns and improve user experience. These are only activated after user consent.
- Page view counts and visit duration analysis
- User traffic source identification
- Popular tools and features identification
- Service error and performance monitoring
3. Advertising Cookies (Google AdSense)
We use Google AdSense to deliver relevant advertisements. These are only activated after user consent.
- Personalized ads based on user interests
- Ad effectiveness measurement and analysis
- Ad frequency control (preventing the same ad from showing repeatedly)
How to Manage Cookies
You can manage cookies in the following ways.
- Select 'Essential Only' on the cookie consent banner shown on your first visit to block analytics and advertising cookies.
- Delete or block cookies in your browser settings. Note that blocking essential cookies may limit some service features.
- Disable personalized ads in Google's ad personalization settings (adssettings.google.com).
- Clearing your browser's localStorage will reset all saved settings.
Third-Party Cookies
Clock-Tani uses Google Analytics (analytics) and Google AdSense (advertising) as third-party services. These services set cookies according to their own cookie policies. For more information, please refer to Google's Privacy Policy (policies.google.com/privacy).
