What the Extension Does

offline.translator reads text from webpages you choose to translate, processes that text locally, and updates the page with translated text. It can also optionally refine translations using Chrome's built-in on-device AI capabilities, including Gemini Nano when available in Chrome.

The extension is designed for local processing. Its translation engine uses Google's built-in Translator API in Chrome and Chrome's built-in AI capabilities on the device, rather than sending page content to an external service.

Information Processed by the Extension

The extension may process the following data locally on your device:

webpage text that appears on pages you choose to translate
page metadata such as visible placeholders, page titles, and image alt text when these are translated as part of the page
user-selected settings such as source language, target language, translation scope, UI preferences, and optional feature settings
locally cached translation records used to speed up repeat translations on your device

What We Store

offline.translator stores data locally in the browser, including:

user preferences in Chrome storage
translation cache records in local browser storage such as IndexedDB
optional UI and workflow settings needed to preserve your preferred experience across sessions

This local storage is used only to make the extension work, improve repeat translation speed, and preserve your settings.

What We Do Not Collect or Send to Our Servers

offline.translator does not run a translation server. We do not collect, receive, sell, or share your webpage text, translations, or local cache contents.

In particular, the extension does not intentionally send the following to developer-controlled servers:

webpage text
translated output
browsing content for translation
local cache contents
user language preferences for analytics or advertising purposes

Built-in Browser AI and Model Downloads

offline.translator relies on AI capabilities built into Chrome, such as the built-in Translator API and built-in on-device AI features including Gemini Nano where available. If Chrome needs to download, update, or manage language or AI models, that process is controlled by Chrome or the platform, not by this extension. Any such downloads are handled by Chrome, not by us.

Permissions and Why They Are Used

offline.translator requests only the permissions needed to provide on-device translation features:

activeTab to act on the page the user has chosen to translate

storage to save settings and local preferences

tabs to target and synchronize with the correct tab

webNavigation to stay aligned with page and frame navigation changes

sidePanel to provide the main translation interface without covering page content

offscreen to run built-in AI tasks in an offscreen extension context when needed

notifications to show user-facing status updates such as optimization progress or completion

Data Sharing

offline.translator does not sell personal information and does not share webpage text or translation content with any external services.

Data Retention and User Control

Because data is stored locally on your device, you control it through your browser and extension settings. You can remove the extension, clear browser storage, or clear local extension data to remove locally stored settings and cached translations.

Security

offline.translator is designed to keep processing on your device. The extension packages its code with the extension and does not fetch or execute remote code.

Children's Privacy

offline.translator is not designed for children. If you are responsible for a child using the browser, you should supervise extension use the same way you supervise browsing activity in general.

Changes to This Privacy Policy

This Privacy Policy may be updated occasionally to reflect changes in the extension or applicable requirements. The latest version will be published alongside the extension.
