Privacy Policy
Last updated: July 1, 2026
This Privacy Policy explains how Kkachi Work Clock (the “Service”) handles your information. The Service works without any sign-up, and the work records you enter are never sent to a server.
1. Information We Collect
The Service does not collect directly identifiable information such as your name, email address or phone number.
The clock-in, clock-out, break and meal timestamps you record are stored only in your browser's local storage (localStorage) and are never transmitted to or shared with the operator or any third party.
Separately, the Service uses a third-party analytics tool to collect anonymous, aggregated usage statistics, as described in Section 3.
2. Where Data Is Stored
All work records live entirely on your device. Clearing your browser data, leaving private/incognito mode, or uninstalling the app may delete your records, so please use the “Export” feature to back them up when needed.
3. Cookies and Analytics
The Service uses Google Analytics to understand aggregate usage and improve quality. Google Analytics sets cookies and collects standard, non-identifying usage data such as the pages you view, an approximate region derived from your IP address, your device and browser type, and the referring source.
This analytics data is processed by Google on the operator's behalf under Google's own privacy policy, and is never linked to the work records you enter, which never leave your device. The Service does not use cookies for advertising identifiers.
You can opt out at any time by installing the Google Analytics Opt-out Browser Add-on or by blocking cookies in your browser.
4. Third-Party Sharing
The Service does not sell or rent your information. Aside from the anonymous analytics data handled by Google as a processor (see Section 3), your information is not provided to third parties.
5. Your Rights
You can permanently delete your stored records at any time using the “Delete all data” feature in the app. Because the data exists only on your device, deletion is immediate and irreversible.
6. Children's Privacy
Because the Service collects no personal information there is no age restriction, but children under 14 are encouraged to use it under the guidance of a guardian.
7. Contact
For questions about this policy, please contact the Service operator.
