Privacy Policy

Last updated: June 9, 2026  ·  Effective: June 9, 2026

Short version: Clingogo extensions run entirely on your device. We do not collect, store, or transmit your browsing data, personal information, or usage history. Ever.

1. Who We Are

Clingogo is an independent Chrome extension studio operated by Do Viet Quang, based in Ho Chi Minh City, Vietnam. We build and maintain browser extensions distributed through the Chrome Web Store.

5. Permissions

Our extensions request only the permissions necessary to function. For example, a dark mode extension requires access to page content to apply CSS — this access is used solely to render the dark theme and is never logged or transmitted.

We will always explain in the Chrome Web Store listing why each permission is needed.

6. Third-Party Services

Our extensions do not embed third-party analytics, advertising SDKs, or tracking pixels. The only third-party interaction is:

7. Children's Privacy

Our extensions and services are not directed at children under 13. We do not knowingly collect any information from children. If you believe a child has provided us information, please contact us immediately at support@clingogo.com.

8. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of our extensions after any changes constitutes acceptance of the new policy.
