Privacy Policy for WebLang Translator

Last Updated: March 22, 2026

Overview

WebLang Translator is a Chrome extension for translating web content, running optional AI analysis, generating optional Gemini text-to-speech output, exporting results, and storing a small local translation history. This policy explains what data the extension accesses, stores, and sends to third-party services.

WebLang Translator does not use a developer-operated backend. Extension activity runs in your browser and, when required, through third-party providers that process your requests.

Data the Extension Can Access

Depending on the features you use, the extension may access:

• Text visible on the web page you choose to translate
• Text you select manually for quick translation
• Translated output generated by the extension
• Text you send to AI analysis or Gemini TTS
• Page metadata needed for translation history, including page URL and page title
• Settings you configure, including provider preferences, UI preferences, and feature toggles
• API keys you provide for Google, Azure, or Gemini services

The extension is not intended to collect personal data for the developer. However, the text you translate or analyze may include personal or sensitive information depending on the site you use.

Data Stored in the Browser

Sync Storage

WebLang Translator stores part of its configuration in chrome.storage.sync.

This may include:

• Source and target language preferences
• Translation mode
• Quick Translate preference
• Auto Translate from History preference
• Tooltip and display preferences
• Optional home feature toggles
• Translation provider selection
• Gemini model and Gemini voice preferences
• API keys you enter for supported providers

Depending on your browser account settings, sync storage may be synchronized by the browser vendor across signed-in devices.

Local Storage

The extension stores recent translation history in chrome.storage.local.

History entries may include:

• Page URL
• Page title
• Translation mode
• Source language
• Target language
• Translation timestamp
• Approximate translated word count

History is used to show recent activity and to support automatic re-translation when a page URL exactly matches a saved history entry and the feature is enabled.

The extension also stores the latest AI output locally when needed for export actions.

Session Storage

The translation engine may cache translation results temporarily in sessionStorage inside the active tab to reduce repeated translation work during the current tab session.

How Data Is Used

The extension uses accessed and stored data only to provide the features you request, including:

• Translating selected text or page content
• Re-applying translation on pages that match saved history entries
• Running optional AI summarize, analyze, or keyword extraction
• Running optional Gemini TTS
• Exporting translation or AI results
• Showing history and status information in the extension UI

Third-Party Requests

Translation Providers

When you use translation features, the text being translated may be sent to one or more supported providers, depending on your settings and fallback behavior.

Supported providers in the current project include:

• Google Cloud Translation API
• Google Translate web endpoints
• Microsoft Azure Translator
• MyMemory
• LibreTranslate

Requests may include the text being translated, source language, target language, and your API key when required by the provider.

AI and TTS Providers

If you enable and use AI Analysis or Gemini TTS, the relevant text may be sent to Google Gemini.

This can include requests for:

• Summaries
• Analysis
• Keyword extraction
• Gemini text-to-speech generation

Requests may include technical parameters such as target language, model name, selected voice, and your Gemini API key.

No Developer Backend

WebLang Translator does not send user data to a backend controlled by the developer. Data is sent only to third-party services required to process the features you actively use.

Data Sharing and Sale

We do not sell user data.

We do not operate a separate backend that receives your translation history, settings, page content, or AI requests. Data is transmitted only to the third-party providers needed for the feature you choose to use.

Permissions Used

Permission or Access	Purpose
storage	Save extension settings, AI result metadata, and translation history
activeTab	Support user-initiated tab interactions where needed
scripting	Inject scripts or CSS used by extension features
downloads	Export translation and AI results to local files
sidePanel	Display the extension UI in Chrome’s side panel
contextMenus	Add translation actions to the browser context menu
alarms	Keep background work alive during longer translation tasks
Access to http and https pages through content scripts	Read page text and apply translations on supported websites
Host permissions for provider endpoints	Send requests to translation and AI services used by the extension

Retention

• Settings remain stored until you change them, clear extension storage, or uninstall the extension
• Local history remains stored until you clear it or remove extension storage
• Session cache remains tied to the active tab session
• Exported files remain wherever you choose to save them

Security

Stored data relies on the browser’s extension storage model and the security controls of the browser. Third-party providers process requests under their own systems and privacy terms.
