Server logs

Like every website, our hosting provider records technical access logs: IP address, date and time, the page requested, and your browser’s identification. These are used only to keep the site secure and running, on the basis of our legitimate interest (Article 6(1)(f) GDPR), and are deleted automatically by the hosting provider after a short period.

Time measurements

To measure your connection, your browser requests the time from our server several times. These requests contain no personal information beyond what appears in the server logs, and the results are calculated in your browser, not stored by us.

Stored in your browser

Your display choices (colour theme, 12 or 24-hour format, milliseconds, the countdown you set) are saved in your browser’s local storage so they are still there next time. They never leave your device. You can delete them by clearing this site’s data in your browser.

Cookies and your consent

The clock and all other features work without cookies. We only use the services below if you agree in the cookie banner. You can agree to each separately, and change or withdraw your choice at any time with “Cookie settings” at the bottom of every page. We store your choice in a cookie called consent for 180 days. The legal basis is your consent (Article 6(1)(a) GDPR).

Google Analytics

With your consent we use Google Analytics 4, a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, to count visits and see which pages are used. It records, for example, the pages you view, how long you stay, the website that referred you, your approximate location (country or city), and your type of device and browser. Google Analytics 4 does not log or store IP addresses. It sets cookies whose names start with _ga, kept for up to two years, to recognise returning visits.

We use this information only in aggregated form to improve the site. We do not combine it with other data and do not use it for advertising. Analytics data is deleted automatically after the retention period we have set, at most 14 months. Google may process data in the United States; Google is certified under the EU–US Data Privacy Framework. More information: Google’s privacy policy.

Advertising

With your consent we show ads from Google AdSense. Google, as an independent controller, uses cookies and similar technology to show and measure ads. See how Google uses information from sites that use its services.

Contact form

If you write to us, we receive your name, email address and message by email, and a copy is stored on our server in case the email does not arrive. We use them only to reply. Copies are deleted automatically after one year at the latest.

Fonts and other content

All fonts, scripts and images are served from this site. Nothing is loaded from third parties, except Google’s services described above, and only after you consent. The exact time itself comes from our own reference clock server.

Your rights

You have the right to access, correct and delete your personal data, to restrict or object to its processing, and to data portability. Write to the address above. You may also complain to a data protection authority; in Bulgaria this is the Commission for Personal Data Protection (cpdp.bg).
