Privacy Policy

Last updated: 2026-06-02

Clock-Tani (the 'Service') is a free web service operated by an indie developer, Tani. Hosting is funded by Google AdSense revenue. With your consent, ads are personalized; without consent, non-personalized ads may still be shown. This Privacy Policy explains what information we collect and how we use it.

1. Information We Collect

The Service does not require registration and does not directly collect personal identifying information such as names, emails, or phone numbers.

  • Automatically collected information: Browser type, access time, page views, device information (collected via Google Analytics in a form that does not directly identify individuals — IP partial masking, cookie IDs, and other pseudonymous identifiers)
  • Locally stored data: Clock settings, themes, language preferences are stored only in your browser's localStorage and are never transmitted to our servers

2. How We Use Information

Collected information is used only for the following purposes:

  • Analyzing usage statistics to improve the service
  • Ensuring stable service operation and addressing errors
  • Funding service operating costs through advertising

3. Third-Party Services & Advertising

The Service uses the following third-party services. Some of them collect visit information via cookies and identifiers.

  • Google Analytics: Collects visitor statistics (uses cookies). Google's Privacy Policy applies.
  • Google AdSense and advertising partners: Google and some advertising partners use cookies and advertising identifiers (including the DoubleClick DART cookie) to serve personalized ads based on your visits to this site and other sites.
  • Opt out of Google personalized ads: You can disable personalized ads at any time in Google Ad Settings (https://adssettings.google.com).
  • Third-party ad partner opt-out: Cookie policies and opt-out options for advertising partners are available at https://policies.google.com/technologies/ads, the Digital Advertising Alliance (US) http://www.aboutads.info, and the European Digital Advertising Alliance http://www.youronlinechoices.eu.

4. Cookies

The Service does not create identifying cookies on its own, but Google Analytics uses cookies for statistics collection and Google AdSense uses cookies and advertising identifiers (including the DART cookie) to serve personalized ads. You can block cookies via your browser settings or the opt-out links above. If blocked, ads may be shown as non-personalized and some features may be limited.

5. Data Retention & Deletion

Data stored in localStorage is immediately removed when you clear your browser data. Google Analytics data is subject to Google's retention policies.

6. Your Rights

You can view and delete localStorage data at any time through your browser's developer tools or settings. You have the right to block cookies and disable ad personalization.
