Effective date: August 14, 2026 Mouseover Translator performs translation processing on the user's device to protect personal information and webpage content.

1. Introduction

ChoiHanyoung (the "Developer") respects the privacy of users of the Mouseover Translator Chrome extension (the "Extension"). This Privacy Policy explains how the Extension handles user information and webpage content.

2. Information Handled by the Extension

The Extension does not provide user registration and does not collect or transmit names, addresses, telephone numbers, email addresses, payment information, or account authentication information to the Developer.

The following information is processed locally on the user's device to provide the Extension's features.

Category	Information handled	Purpose	Retention
Webpage text	A word, sentence, or paragraph over which the user places the mouse pointer	Translation and source-language detection	Up to 200 results may be cached temporarily in memory for the current page and are deleted when the page is refreshed or closed
Extension settings	Enabled status, source and target languages, translation scope, source highlighting, and contextual translation preferences	Remembering user preferences	Stored in Chrome extension storage and manageable by changing the settings or uninstalling the Extension

The Extension excludes text fields, password fields, editable areas, hidden elements, images, Canvas, and SVG content from translation processing.

3. How Information Is Used

Webpage text is used only to provide the translation and source-language detection requested by the user. Translation and language detection are performed on the user's device through Chrome's built-in Translator API and Language Detector API.

The Extension does not:

Transmit webpage text or translation results to the Developer's servers or to an external translation server
Collect browsing history, URLs, cookies, or search history
Use advertising, personalized advertising, or user tracking
Use analytics or telemetry tools
Sell user information or provide it to third parties
Allow the Developer or any other person to read the user's webpage text or translation results

Chrome may separately download translation or language-detection models when required. Chrome manages this process, and the Extension does not transmit text submitted for translation to a model download server.

4. Chrome Storage and Sync

The enabled status is stored in chrome.storage.local. Language preferences, translation scope, source highlighting, and contextual translation preferences are stored in chrome.storage.sync. If the user enables Chrome Sync, these settings may be synchronized through the user's Google Account to other Chrome environments used by the user.
