Privacy Policy

Last updated: June 2026

This Privacy Policy explains how Gong Clock ("we", "our", or "the app") handles information when you use our free online clock at this website. We respect your privacy and are committed to protecting it.

1. Information We Collect

Gong Clock does not collect, store, or transmit any personal data directly. The app runs entirely in your browser. We do not have accounts, logins, or user profiles.

The following preferences are saved in your browser's local storage so the app remembers them between visits. They never leave your device and are never sent to our servers:

• Your selected colour theme
• Timezone selection
• Gong sound preference, volume level, and whether the gong is muted
• Display preferences (12-hour or 24-hour format, and whether the date is shown)

Alarms you set are held in memory for the current session only and are not saved between visits.

This data remains on your device and is cleared when you clear your browser storage.

2. Google AdSense

We use Google AdSense to display advertisements. Google and its partners may use cookies and similar tracking technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out via aboutads.info.

For more information about how Google uses data, see Google's Privacy Policy.

3. Analytics

We may use anonymous analytics tools (such as Google Analytics) to understand aggregate usage patterns (e.g., which features are used most). This data is anonymised and not linked to individual users.

4. Cookies

Gong Clock itself does not set cookies. Third-party advertising services (Google AdSense) may set cookies for ad personalisation. You can control cookie settings through your browser preferences.

5. Service Workers & Offline Use

Gong Clock is a Progressive Web App (PWA). It uses a service worker to cache app assets for offline use. This caching is local to your device and does not involve sending data to our servers.

6. Children's Privacy

Gong Clock is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can delete it.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the app after changes constitutes acceptance of the updated policy.
