LingoLumi Chrome Extension Privacy Policy

Effective date: June 15, 2026

Overview

LingoLumi is a language learning browser extension operated by Xiamen Xiekaimier Information Technology Co., Ltd. This policy explains how the Chrome extension handles user data.

Information We Handle

The extension may process text that you intentionally select, type, or submit for language learning features such as translation, explanation, vocabulary assistance, reading support, or AI-powered learning interactions.

Depending on the permissions you grant, the extension may also access the active tab URL or visible page content only when needed to provide a user-facing learning feature that you request.

How We Use Information

We use handled information only to provide and improve the extension's user-facing language learning features. We do not sell user data, use it for interest-based advertising, or transfer it for unrelated purposes.

Data Sharing

When a feature requires server-side processing, the extension may transmit the submitted text or necessary request data to our service providers solely to deliver that feature. Service providers are used only as necessary for language learning, translation, speech, search, or AI processing functionality.

Chrome Web Store Limited Use

The extension's use and transfer of information received from Chrome APIs complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide or improve the extension's single purpose and user-facing features.

Security

Data transmitted by the extension is sent over secure HTTPS connections. We apply reasonable technical and organizational safeguards to protect information handled by the extension.

Data Retention

We retain information only for as long as necessary to provide the requested service, maintain security, comply with legal obligations, or resolve support issues. You may contact us to request deletion of data associated with your use of the extension.

Your Choices

You can stop using the extension at any time, disable permissions in Chrome, or uninstall the extension. Some features may not work without the permissions or data needed to provide them.
